The composition of gasolines varies widely, depending on the crude oils used, the refinery processes available, the overall balance of product demand, and the product specifications. 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. Viscosity, surface tension, and ignition tendency of fuel are important fuel property parameters in diesel fuels. Robert E. Allen, Director of Information, American Petroleum Institute. With the increased use of thermally cracked gasolines came an increased concern regarding its effects on abnormal combustion, and this led to research for antiknock additives. . The chief risks of such leaks come not from vehicles, but from gasoline delivery truck accidents and leaks from storage tanks. "The Impact of Childhood Lead Exposure on Crime". [39], The development of 100-octane aviation gasoline on an economic scale was due in part to Jimmy Doolittle who had become Aviation Manager of Shell Oil Company. [citation needed] In parts of the United States, ethanol is sometimes added to gasoline without an indication that it is a component. [104] Unburnt gasoline and evaporation from the tank, when in the atmosphere, reacts in sunlight to produce photochemical smog. When this particular hydrocarbon range is distilled, it is sometimes used in the denaturing of alcohol that is meant to be used as a fuel source. The National Institute for Occupational Safety and Health (NIOSH) has also designated gasoline as a carcinogen. National Bureau of Economic Research. These tests showed that in certain aircraft, motor vehicle gasolines performed as well as "High-Test" but in other types resulted in hot-running engines. [36], During this period, research showed that hydrocarbon structure was extremely important to the antiknocking properties of fuel. At the refinery, the composition varies according to the crude oils from which it is produced, the type of processing units present at the refinery, how those units are operated and which hydrocarbon streams (blendstocks) the refinery opts to use when blending the final product.[64]. [118] In 2012, the issue once again made the news media in Canada.[119]. 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. The remainder are products ranging from tar to naphtha.[70]. If left undiluted, improper operation will occur and this may include engine damage from misfiring or the lack of proper action of the fuel within a fuel injection system and from an onboard computer attempting to compensate (if applicable to the vehicle). [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. By 30 October, the death toll had reached five. [103] This total was equivalent to 83% of total U.S. transportation-sector CO2 emissions and equivalent to 29% of total U.S. energy-related CO2 emissions in 2015. gallon. 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. 8 The debate inside the Japanese government as to its oil and gasoline situation was leading to invasion of the Dutch East Indies but this would mean war with the U.S. whose Pacific fleet was a threat to their flank. By 1937, the Army established 100-octane as the standard fuel for combat aircraft and to add to the confusion, the government now recognized 14 different grades, in addition to 11 others in foreign countries. The evolution of gasoline followed the evolution of oil as the dominant source of energy in the industrializing world. High levels of detergent can be found in Top Tier Detergent Gasolines. Compounds in Gasoline. [52] World War II marked the first time in U.S. history that gasoline was rationed and the government imposed price controls to prevent inflation. The use of TEL also necessitated other additives, such as dibromoethane. [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. [96], Though gasoline is a naturally colorless liquid, many gasolines are dyed in various colors to indicate their composition and acceptable uses. 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. [100], MTBE was phased out in the U.S. due to groundwater contamination and the resulting regulations and lawsuits. Karl Griesbaum et al. Is it C8H18?
