These early fuels were termed "straight-run" gasolines and were byproducts from the distillation of a single crude oil to produce kerosene, which was the principal product sought for burning in kerosene lamps. Because captured supplies and oil fields would be necessary to fuel the campaign, the German high command created a special squad of oil-field experts drawn from the ranks of domestic oil industries. Commercial aviation was slower to adapt to jet propulsion and until 1958 when the Boeing 707 first entered commercial service, piston powered airliners still relied on aviation gasoline. High-resolution gas chromatogram showing the components of petroleum refinery gasoline. Later in the war the C-3 grade was improved to where it was equivalent to the U.S. 150 grade (rich mixture rating).[47]. [94][95] Ethanol has been found in at least one study to damage catalytic converters. [30] Also the volatility was decreasing to the point that fuel did not vaporize and was sticking to spark plugs and fouling them, creating hard starting and rough running in winter and sticking to cylinder walls, bypassing the pistons and rings and going into the crankcase oil. Gasoline is a product of petroleum refining that varies in composition and often includes additives such as antiknock agents, antioxidants, lubricants, and detergents. Users have been advised to keep gasoline containers more than half full and properly capped to reduce air exposure, to avoid storage at high temperatures, to run an engine for ten minutes to circulate the stabilizer through all components prior to storage, and to run the engine at intervals to purge stale fuel from the carburetor.[63]. National Bureau of Economic Research. Previously, catalytically or thermally cracked gasolines were most susceptible to oxidation. Gasoline stability requirements are set by the standard ASTM D4814. This reality set a practical limit to how high compression ratios could increase relative to how expensive the gasoline would become. When gasoline is not stored correctly, gums and solids may result, which can corrode system components and accumulate on wetted surfaces, resulting in a condition called "stale fuel". Algeria replaced leaded with unleaded automotive fuel only in 2015. During the early period of gasoline engine development, aircraft were forced to use motor vehicle gasoline since aviation gasoline did not yet exist. Super Unleaded, with 97/98 RON and branded high-performance fuels (e.g. Increasingly important is FCC – fluid catalytic cracked – gasoline. General Motors, DuPont, and Standard Oil, who were partners in Ethyl Corporation, the company created to produce TEL, began to argue that there were no alternatives to leaded gasoline that would maintain fuel efficiency and still prevent engine knocking. The most popular additives include aromatic hydrocarbons, ethers and alcohol (usually ethanol or methanol). The presence of these degradation products in the fuel tank or fuel lines plus a carburetor or fuel injection components makes it harder to start the engine or causes reduced engine performance. ⟶ If the CO2 emissions from ethanol combustion are considered, then about 2.271 kilograms per liter (18.95 lb/US gal) of CO2 are produced when E10 is combusted. There were two grades of aviation gasoline produced in volume in Germany, the B-4 or blue grade and the C-3 or green grade, which accounted for about two-thirds of all production. Tetraethyl lead was one of these additives, and use of leaded gasoline as fuel was responsible for much of the human body burden of this metal for a number of years. Although some sources argue that sniffing was introduced by United States servicemen stationed in the nation's Top End during World War II[120] or through experimentation by 1940s-era Cobourg Peninsula sawmill workers,[121] other sources claim that inhalant abuse (such as glue inhalation) emerged in Australia in the late 1960s. The performance specification also varies with season, with more volatile blends (due to added butane) during winter, in order to be able to start a cold engine. An Atkinson cycle engine uses the timing of the valve events to produce the benefits of a high expansion ratio without the disadvantages, chiefly detonation, of a high compression ratio. As octane numbers increased so did the cost of gasoline but the incremental increase in efficiency becomes less as compression ratio goes up. Ethanol and, to a lesser extent, the ethanol-derived ETBE are common substitutes. [29], The automobile industry reacted to the increase in thermally cracked gasoline with alarm. [58] Last produced in 1955, the Pratt & Whitney R-4360 Wasp Major was using 115/145 Aviation gasoline and producing 1 horsepower per cubic inch at 6.7 compression ratio (turbo-supercharging would increase this) and 1 pound of engine weight to produce 1.1 horsepower. Gasoline, when used in high-compression internal combustion engines, tends to autoignite or "detonate" causing damaging engine knocking (also called "pinging" or "pinking"). The US CDC's Agency for Toxic Substances and Disease Registry says not to induce vomiting, lavage, or administer activated charcoal. Subsequently, low-sulfur gasoline was introduced, in part to preserve the catalysts in modern exhaust systems. The general was so upset at the arrival of a truckload of rations instead of gasoline he was reported to have shouted: "Hell, they send us food, when they know we can fight without food but not without oil. Gasoline with 102 RON may rarely be available for racing purposes. [113] The practice is thought to cause severe organ damage, including mental retardation and cancer. However, the unburned mixture may autoignite by pressure and heat alone, rather than igniting from the spark plug at exactly the right time, causing a rapid pressure rise which can damage the engine. In many areas throughout the U.S., oxygenate blending is mandated by EPA regulations to reduce smog and other airborne pollutants. 3.1 CHEMICAL IDENTITY Gasoline is a refined product of petroleum consisting of a mixture of hydrocarbons, additives, and blending agents. The combustion of octane, a representative species, performs the chemical reaction: 2 The dangers of compounds containing lead were well-established by then and Kettering was directly warned by Robert Wilson of MIT, Reid Hunt of Harvard, Yandell Henderson of Yale, and Erik Krause of the University of Potsdam in Germany about its use. "[130] The Associated Press said premium gas—which has a higher octane rating and costs more per gallon than regular unleaded—should be used only if the manufacturer says it is "required". In the late 1910s, researchers such as A.H. Gibson, Harry Ricardo, Thomas Midgley Jr. and Thomas Boyd began to investigate abnormal combustion. This situation led to the decision to attack the U.S. fleet at Pearl Harbor before proceeding with the Dutch East Indies invasion. [4] Gasoline contains benzene and other known carcinogens. Gasoline. [61] At 535 pounds (243 kg) (1959 with aluminum intake), it took 1.9 pounds (0.86 kg) of engine weight to make 1 horsepower (0.75 kW). [99], Oxygenate blending adds oxygen-bearing compounds such as MTBE, ETBE, TAME, TAEE, ethanol and biobutanol. To further complicate the situation, as engine performance increased, the altitude that aircraft could reach also increased, which resulted in concerns about the fuel freezing. The record of gasoline consumption by the Army prior to June, 1943, was uncoordinated as each supply service of the Army purchased its own petroleum products and no centralized system of control nor records existed. Most fuel pumps display a sticker that states that the fuel may contain up to 10% ethanol, an intentional disparity that reflects the varying actual percentage. ��.�M9yaLA��E�{�2-í/�U��?��~���ny���#��"L_�He�� What is the difference Between Ethanol and Gasoline – Comparison of Key Differences Key Terms: C 2 H Throughout the duration of the war, aviation gasoline supply was always behind requirements and this impacted training and operations. This lower density is a property of the lower molecular weight of propane (LPG's chief component) compared to gasoline's blend of various hydrocarbon compounds with heavier molecular weights than propane. Gasoline has a lower explosive limit of 1.4% by volume and an upper explosive limit of 7.6%. Molecular weights of the representative octane combustion are C8H18 114, O2 32, CO2 44, H2O 18; therefore 1 kg of fuel reacts with 3.51 kg of oxygen to produce 3.09 kg of carbon dioxide and 1.42 kg of water. Lead replacement petrol (LRP) was developed for vehicles designed to run on leaded fuels and incompatible with unleaded fuels. Hence, the exact chemical composition of gasoline is undefined. [69] On average, about 74 L (19.5 US gal; 16.3 imp gal) of gasoline are available from a barrel of crude oil (about 46% by volume), varying with the quality of the crude and the grade of the gasoline. The earliest straight-run gasolines were the result of distilling eastern crude oils and there was no mixing of distillates from different crudes. [129], About 9 percent of all gasoline sold in the U.S. in May 2009 was premium grade, according to the Energy Information Administration. In the EU, 5% ethanol can be added within the common gasoline spec (EN 228). In Finland, Sweden and Norway, 95 RON is the standard for regular unleaded gasoline and 98 RON is also available as a more expensive option. The reason for this shortage developed before the war even began. The possible reasons for variations in physical and chemical properties have been discussed. [71] [72] [73]. It was also found that gasolines from aromatic and naphthenic base crude oils from California, South Texas and Venezuela resulted in smooth-running engines. Had the Japanese destroyed the oil," he added, "it would have prolonged the war another two years. [41], In 1937, Eugene Houdry developed the Houdry process of catalytic cracking, which produced a high-octane base stock of gasoline which was superior to the thermally cracked product since it did not contain the high concentration of olefins. Gasoline is produced to meet a host of engine performance specifications and many different compositions are possible. 145-45 MANUFACTURE OF AVIATION GASOLINE IN GERMANY", "MotorCities - One Horsepower per Cubic Inch: 1957 Chevy Corvette | 2018 | Story of the Week",,, "Lead-Free gasoline Material Safety Data Sheet", "Oil Industry Statistics from Gibson Consulting", "Quality of petrol and diesel fuel used for road transport in the European Union (Reporting year 2013)", "85-octane warning labels not posted at many gas stations", "95/93 – What is the Difference, Really? The oxidation of ethanol can form ethanol such as acetaldehyde, an organic chemical compound present in coffee, fresh bread, and fruits. The federal requirement that RFG contain oxygen was dropped on 6 May 2006 because the industry had developed VOC-controlled RFG that did not need additional oxygen. [63] Hydrocarbons with a bromine number of 10 or above can be protected with the combination of unhindered or partially hindered phenols and oil-soluble strong amine bases, such as hindered phenols. The exact chemical composition of gasoline varies depending on its grade or octane rating, but generally speaking it is a mixture of combustible hydrocarbons. European countries began replacing lead-containing additives by the end of the 1980s, and by the end of the 1990s, leaded gasoline was banned within the entire European Union. If the concentration is below 1.4%, the air-gasoline mixture is too lean and does not ignite. The chemical properties (namely RON and Reid vapor pressure) of the straight-run gasoline can be improved through reforming and isomerisation. These would often be used in aircraft engines. On 7 December, 1941, Japan attacked Pearl Harbor and the next day the Netherlands declared war on Japan which initiated the Dutch East Indies campaign. The engine effects produced by abnormal combustion (engine knocking and pre-ignition) due to inferior fuels had not yet been identified, and as a result there was no rating of gasoline in terms of its resistance to abnormal combustion. This octane rating describes the quality of the fuel, and the value is based off the ratios of two compounds in the gasoline - specifically iso-octane, a compound with the same chemical formula as octane but with a slightly different structure and properties, and normal hept… Conversely, LPG's energy content by weight is higher than gasoline's due to a higher hydrogen-to-carbon ratio. As Japanese aggression grew in China (USS Panay incident) and news reached the American public of Japanese bombing of civilian centers, especially the bombing of Chungking, public opinion began to support a U.S. embargo. Prior to the American entry into World War I, the European Allies used fuels derived from crude oils from Borneo, Java and Sumatra, which gave satisfactory performance in their military aircraft. The last of these differs from standard ethanol–gasoline blends in that it consists of 15% hydrous ethanol (i.e., the ethanol–water azeotrope) instead of the anhydrous ethanol traditionally used for blending with gasoline. The first internal combustion engines suitable for use in transportation applications, so-called Otto engines, were developed in Germany during the last quarter of the 19th century. This more detailed methodology has been used by the petrochemical industry to characterize feedstock impacts on product properties derived through chemical processing [8-12]. A gasoline obtained by recovering the butane, pentane and hexane hydrocarbons present in small proportion in certain natural gases. [111][112], Inhaled (huffed) gasoline vapor is a common intoxicant. When the United States entered the war in April 1917, the U.S. became the principal supplier of aviation gasoline to the Allies and a decrease in engine performance was noted. By 1995, leaded fuel accounted for only 0.6 percent of total gasoline sales and under 2,000 short tons (1,800 metric tons) of lead per year. Army Air Forces Historical Studies: No. Typically, gasoline contains more than 150 chemicals including small amounts of benzene, toluene, xylene, and sometimes lead. After the U.S. banned all exports of steel and iron scrap, the next day Japan signed the Tripartite Pact and this led Washington to fear that a complete U.S. oil embargo would prompt the Japanese to invade the Dutch East Indies. Through the German-Soviet Commercial Agreement (1940), Stalin agreed in vague terms to supply Germany with additional oil equal to that produced by now Soviet-occupied Polish oil fields at Drohobych and Boryslav in exchange for hard coal and steel tubing. There are trace amounts of other hydrocarbons present such as benzene. Gasoline inhalation has become epidemic in some poorer communities and indigenous groups in Australia, Canada, New Zealand, and some Pacific Islands. It appeared engine knocking was dependent on a wide variety of parameters including compression, ignition timing, cylinder temperature, air-cooled or water-cooled engines, chamber shapes, intake temperatures, lean or rich mixtures and others. Hence, floats on water. As of 2009, the federal tax is 18.4¢ per gallon for gasoline and 24.4¢ per gallon for diesel (excluding red diesel). [110], Contrary to common misconception, swallowing gasoline does not generally require special emergency treatment, and inducing vomiting does not help, and can make it worse. Vapor pressure initially rises with some addition of ethanol to gasoline, but the increase is greatest at 10% by volume. [96], Though gasoline is a naturally colorless liquid, many gasolines are dyed in various colors to indicate their composition and acceptable uses. �i,Zd�!�}ƫ^M�R�9��_{L%�3 [35], In the five-year period prior to 1929, a great amount of experimentation was conducted on different testing methods for determining fuel resistance to abnormal combustion. Therefore, only (desulphurized) heavy virgin naphtha (HVN) is feed to the reformer unit [64]. "[32], Being very unhappy with the consequent reduction in overall gasoline quality, automobile manufacturers suggested imposing a quality standard on the oil suppliers. The Brazilian National Agency of Petroleum, Natural Gas and Biofuels (ANP) requires gasoline for automobile use to have 27.5% of ethanol added to its composition. Like other hydrocarbons, gasoline burns in a limited range of its vapor phase and, coupled with its volatility, this makes leaks highly dangerous when sources of ignition are present. [10], In most Commonwealth countries, the product is called "petrol", rather than "gasoline". These harmful deposits arise from the oxidation of alkenes and other minor components in gasoline (see drying oils). However, gasoline vapor rapidly mixes and spreads with air, making unconstrained gasoline quickly flammable. GASOLINE may be incompatible with strong oxidizing agents such as nitric acid, peroxides, and perchlorates. All significant properties of fuels ETBE is obtained by catalytic reaction of bioethanol with isobutene (45%/55% in weight): CH 3CH 2OH+(CH The gasoline was 169 0 obj <> endobj 197 0 obj <>/Encrypt 170 0 R/Filter/FlateDecode/ID[<4F6A947C2ED04977BC85E3DF4BB100DA>]/Index[169 59]/Info 168 0 R/Length 128/Prev 833761/Root 171 0 R/Size 228/Type/XRef/W[1 3 1]>>stream Further improvements in engine efficiency were attempted at higher compression ratios, but early attempts were blocked by the premature explosion of fuel, known as knocking. Currently, many countries set limits on gasoline aromatics in general, benzene in particular, and olefin (alkene) content. This situation persisted until 1929. A high expansion ratio is also one of the two key reasons for the efficiency of diesel engines, along with the elimination of pumping losses due to throttling of the intake air flow. even predicted that a nation with a good supply of high-octane gasoline would have the advantage in air power. [5][6][7], "Gasoline" is an English word that denotes fuel for automobiles. The most extensive use of ethanol takes place in Brazil, where the ethanol is derived from sugarcane. "We had about 4 1⁄2 million barrels [720,000 m3] of oil out there and all of it was vulnerable to .50 caliber bullets. O The presence of these oxygenates reduces the amount of carbon monoxide and unburned fuel in the exhaust. Since ingesting large amounts of gasoline can cause permanent damage to major organs, a call to a local poison control center or emergency room visit is indicated. Later flight tests conducted in 1937, showed that an octane reduction of 13 points (from 100 down to 87 octane) decreased engine performance by 20 percent and increased take-off distance by 45 percent. This rise in vapor pressure could be mitigated by increasing or decreasing the percentage of ethanol in the gasoline mixture. Gasoline containing ethanol is especially subject to absorbing atmospheric moisture, then forming gums, solids or two phases (a hydrocarbon phase floating on top of a water-alcohol phase). [35] In November, the New Jersey Labor Commission closed the Bayway refinery and a grand jury investigation was started which had resulted in no charges by February 1925. [22] It is estimated that the rating equivalent of these straight-run gasolines varied from 40 to 60 octane and that the "High-Test", sometimes referred to as "fighting grade", probably averaged 50 to 65 octane.[23]. VWA – Volume weighted average Contact Us to ask a question, provide feedback, or report a … In 1929, the octane rating scale was adopted, and in 1930, the first octane specification for aviation fuels was established. [45] By the spring of 1941 and the depletion of German gasoline reserves, Adolf Hitler saw the invasion of Russia to seize the Polish oil fields and the Russian oil in the Caucasus as the solution to the German gasoline shortage. The US automobile industry after WWII could not take advantage of the high octane fuels then available. By 1944, the U.S. was producing over 1.5 billion barrels a year (67 percent of world production) and the petroleum industry had built 122 new plants for the production of 100-octane aviation gasoline and capacity was over 400,000 barrels a day – an increase of more than ten-fold. On resumption of regular engine use, the buildup may or may not be eventually cleaned out by the flow of fresh gasoline. In the United States, octane ratings in unleaded fuels vary between 85[74] and 87 AKI (91–92 RON) for regular, 89–90 AKI (94–95 RON) for mid-grade (equivalent to European regular), up to 90–94 AKI (95–99 RON) for premium (European premium). Automobile compression ratios increased from an average of 5.3-to-1 in 1931 to just 6.7-to-1 in 1946. B-4 was equivalent to 89-octane and the C-3 was roughly equal to the U.S. 100-octane, though lean mixture was rated around 95-octane and was poorer than the U.S. The data are reported to EPA for every batch of gasoline produced at the refinery, blended at terminals or imported into to the U.S., and sold in the U.S. In 1938, the area that would become Nazi-occupied would produce 575,000 barrels per day. In 1940, total production under German control amounted to only 234,550 barrels (37,290 m3)—a shortfall of 59 percent. : Premium Gasoline Delivers Premium Benefits to Your Car", "Why is summer fuel more expensive than winter fuel? Gasoline, as delivered at the pump, also contains additives to reduce internal engine carbon buildups, improve combustion and allow easier starting in cold climates. By 1941, principally through the efforts of the Cooperative Fuel Research Committee, the number of grades for aviation fuels was reduced to three: 73, 91 and 100 octane. The 1970s witnessed greater attention to the environmental consequences of burning gasoline. Some important streams include: The terms above are the jargon used in the oil industry and terminology varies. [124] Opal is a non-sniffable fuel (which is much less likely to cause a high) and has made a difference in some indigenous communities. Properties of Fuels (a) Propert y Gaso Dies No.2 el Fuel MethanolEthanol MTBE Propane Compresse Natural Gas d Biodiesel Chemical Formula C4 C 8 to C25 CH3OH (CH3)3COC C3H8 CH4 (83-9 … Beginning in 1916, Charles F. Kettering began investigating additives based on two paths, the "high percentage" solution (where large quantities of ethanol were added) and the "low percentage" solution (where only 2–4 grams per gallon were needed). Gasoline is a complex mixture of hydrocarbons primarily pentane, hexane, and octane. Gasoline or petrol is a fuel, derived from petroleum crude oil, for use in spark-ignited internal combustion engines. CHAPTER 5 presents experimental data for physico- chemical properties (density, viscosity, refractive index) of gasoline – alcohol blends: gasoline +etanol, gasoline +i-propanol and gasoline +n-butanol over a wide range of composition and temperature for which data are not �X� �E�� ����+��=�p��_ Maximum output achieved in 1943 reached 52,200 barrels a day before the Allies decided to target the synthetic fuel plants. However, the declining number of such cars on British roads saw many gasoline stations withdrawing LRP from sale by 2003. Countries in Europe impose substantially higher taxes on fuels such as gasoline when compared to the United States. [114][115][116][117], In Canada, Native children in the isolated Northern Labrador community of Davis Inlet were the focus of national concern in 1993, when many were found to be sniffing gasoline. The octane rating of typical commercially available gasoline varies by country. This area had never been self-sufficient in oil before the war. The type needs more references which specific on compositions of each fuel, plus cites, to avoid vagueness in numbers, Army Air Forces Historical Studies: No. (*) Diesel fuel is not used in a gasoline engine, so its low octane rating is not an issue; the relevant metric for diesel engines is the cetane number. When they were engaged in combat across open country, gasoline consumption almost doubled. When the Allied breakout after D-Day found their armies stretching their supply lines to a dangerous point, the makeshift solution was the Red Ball Express. … ; This page was last edited on 22 January 2021, at 22:43. [34][35] On 27 October 1924, newspaper articles around the nation told of the workers at the Standard Oil refinery near Elizabeth, New Jersey who were producing TEL and were suffering from lead poisoning. The solution appeared in 1911, when the development of the Burton process allowed thermal cracking of crude oils, which increased the percent yield of gasoline from the heavier hydrocarbons. "The Impact of Childhood Lead Exposure on Crime". Roughly 19 U.S. gallons (72 L) of gasoline is derived from a 42-U.S.-gallon (160 L) barrel of crude oil. They are more characterized by their physical properties such as flammability and solvency. The trucks in the convoys had to drive longer distances as the armies advanced and they were consuming a greater percentage of the same gasoline they were trying to deliver. [59] It would not be until 1957 that the first US automobile manufacturer could mass-produce an engine that would produce one horsepower per cubic inch, the Chevrolet 283 hp/283 cubic inch V-8 engine option in the Corvette. Almost all countries in the world have phased out automotive leaded fuel. Three different ethanol blends are sold in the Netherlands—E5, E10 and hE15. [100], MTBE was phased out in the U.S. due to groundwater contamination and the resulting regulations and lawsuits.
