Car longevity is of interest to many car owners [1] and includes several things: maximum service life in either mileage or time (duration), relationship of components to this lifespan, identification of factors that might afford control in extending the lifespan. Barring an accidental end to the lifespan, a car would have a life constrained by ...
The following is a list of countries by combustion engine exports. Data is from 2018, in billions of United States dollars, as reported by The Observatory of Economic Complexity. Currently, the top ten countries are listed: #
This is especially true for Healthy life expectancy, the definition of which criteria may change over time, even within a country. For example, Canada is a country with a fairly high overall life expectancy at 81.63 years; however, this number decreases to 75.5 years for Indigenous people in the country. [4]
This is a list of countries showing past life expectancy, ranging from 1950 to 2015 in five-year periods, as estimated by the 2017 revision of the World Population Prospects database by the United Nations Population Division. Life expectancy equals the average number of years a person born in a given country is expected to live if mortality ...
1952 Shell Oil film showing the development of the diesel engine from 1877. The diesel engine, named after the German engineer Rudolf Diesel, is an internal combustion engine in which ignition of diesel fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is called a compression-ignition engine (CI engine).
Most petrol (gasoline, Otto cycle) and diesel (Diesel cycle) engines have an expansion ratio equal to the compression ratio. Some engines, which use the Atkinson cycle or the Miller cycle achieve increased efficiency by having an expansion ratio larger than the compression ratio. Diesel engines have a compression/expansion ratio between 14:1 ...
World War II delayed dieselisation in the US until the late 1940s; in 1949, the Gulf, Mobile and Ohio Railroad became the first large mainline railroad to convert completely to diesel locomotives, and Life Magazine ran an article on 5 December 1949 titled "The GM&O puts all its steam engines to torch, becomes first major US railroad to ...
The actual amount of mechanical work obtained from fuel (the inverse of the specific fuel consumption) depends on the engine. A figure of 17.6 MJ/kg is possible with a gasoline engine, and 19.1 MJ/kg for a diesel engine. See Brake-specific fuel consumption for more information. [clarification needed]
