Substantial carburetor and ignition system developments were required, and occurred, before high-speed gasoline engines suitable for automobiles became available in the late s. Stationary engine progress also continued. By the late s, large single-cylinder engines of 1. In Britain, legal restrictions on volatile fuels turned their engine builders toward kerosene. Low compression ratio "oil" engines with heated external fuel vaporizers and. His concept of initiating combustion by injecting a liquid fuel into air heated solely by compression permitted a doubling of efficiency over other internal combustion engines.
Much greater expansion ratios, without detonation or knock, were now possible. However, even with the efforts of Diesel and the resources of M. Although a wide variety of experimental rotary engines have been proposed over the years,' the first practical rotary internal combustion engine, the Wankel, was not successfully tested until The earliest engines used for generating mechanical power burned gas.
Gasoline, and lighter fractions of crude oil, became available in the late s and various types of carburetors were developed to vaporize the fuel and mix it with air. Before there were few problems with gasoline; though compression ratios were low 4 or less to avoid knock, the highly volatile fuel made starting easy and gave good cold weather performance. However, a serious crude oil shortage developed, and to meet the fivefold increase in gasoline demand between and , the yield from crude had to be raised.
Through the work of William Burton and his associates of Standard Oil of Indiana, a thermal cracking process was developed whereby heavier oils were heated under pressure and decomposed into less complex more volatile compounds. These thermally cracked gasolines satisfied demand, but their higher boiling point range created cold weather starting problems.
Fortunately, electrically driven starters, introduced in , came along just in time. On the farm, kerosene was the logical fuel for internal combustion engines since it was used for heat and light. Many early farm engines had heated carburetors or vaporizers to enable them to operate with such a fuel.
The period following World War I saw a tremendous advance in our understanding of how fuels affect combustion, and especially the problem of knock. These advances, and others, permitted fuels with better and better antiknock properties to be produced in large quantities; thus engine compression ratios steadily increased, improving power and efficiency.
These factors are, first, the need to control the automotive contribution to urban air pollution and, second, the need to achieve significant improvements in automotive fuel consumption. In , it was demonstrated by Prof. Haagen-Smit that the smog problem there resulted from reactions between oxides of nitrogen and hydrocarbon compounds in the presence of sunlight.
Diesel engines are a significant source of small soot or smoke particles, as well as hydrocarbons and oxides of nitrogen.
As a result of these developments, emission standards for automobiles were introduced first in California, then nationwide in the United States, starting in the early s.
Emission standards in Japan and Europe, and for other engine applications, have followed. Substantial reductions in emissions from spark-ignition and diesel engines have been achieved. Both the use of catalysts in spark-ignition engine exhaust systems for emissions control and concern over the toxicity of lead antiknock additives have resulted in the reappearance of unleaded gasoline as a major part of the automotive fuels market. Also, the maximum lead content in leaded gasoline has been substantially reduced.
The emission-control requirements and these fuel developments have produced significant changes in the way internal combustion engines are designed and operated.
Internal combustion engines are also an important source of noise. There are several sources of engine noise: the exhaust system, the intake system, the fan used for cooling, and the engine block surface. The noise may be generated by aerodynamic effects, may be due to forces that result from the combustion process, or may result from mechanical excitation by rotating or reciprocating engine components. Vehicle noise legislation to reduce emissions to the environment was first introduced in the early s.
During the s the price of crude petroleum rose rapidly to several times its cost in real terms in , and concern built up regarding the longer-term availability of petroleum.
Pressures for substantial improvements in internal combustion engine efficiency in all its many applications have become very substantial indeed. Yet emission-control requirements have made improving engine fuel consumption more difficult, and the removal and reduction of lead in gasoline has forced spark-ignition engine compression ratios to be reduced. Much work is being done on the use of alternative fuels to gasoline and diesel. Of the non-petroleum-based fuels, natural gas, and methanol and ethanol methyl and ethyl alcohols are receiving the greatest attention, while synthetic gasoline and diesel made from shale oil or coal, and hydrogen could be longer-term possibilities.Ii There is a tendency to swing to the left but this can easily be checked with.
