one cycle of a four-stroke diesel engine
A. intake stroke
B. compression stroke
C. power stroke
D. exhaust stroke

in·ter·nal-com·bus·tion engine

(ĭn-tûr′nəl-kəm-bŭs′chən)
n.
An engine, such as an automotive gasoline piston engine or a diesel, in which fuel is burned within the engine proper rather than in an external furnace, as in a steam engine.

internal-combustion engine

n
(Automotive Engineering) a heat engine in which heat is supplied by burning the fuel in the working fluid (usually air)

inter′nal-combus′tion en`gine


n.
an engine of one or more working cylinders in which the process of combustion takes place within the cylinders.

internal-combustion engine
cycles of a four-stroke diesel engine
A. intake stroke: the piston moves down, drawing air and fuel into the cylinder
B. compression stroke: the piston moves up, compressing and heating the air and fuel mixture
C. power stroke: the hot air and fuel mixture ignites, forcing the piston down
D. exhaust stroke: the piston moves up, forcing the exhaust gases out of the cylinder

in·ter·nal-com·bus·tion engine

(ĭn-tûr′nəl-kəm-bŭs′chən)
An engine whose fuel is burned inside the engine itself rather than in an outside furnace or burner. Gasoline and diesel engines are internal-combustion engines; a steam engine is not.

The vans use both a traditional gasoline-powered internal-combustion engine and a battery-powered electric motor.
Scuderi says its design is able to achieve compression cylinder pressures equal to that of a conventional internal-combustion engine during the combustion cycle, thus creating large amounts of turbulence for improved atomization of the fuel/air mix.
The fuel cell, which chemically converts hydrogen to electricity (with water as a byproduct), has the potential to eventually replace the internal-combustion engine, because its far more than just the best environmental choice.
Gasoline automobiles (and the internal-combustion engine which burns gasoline) took over the auto industry for three primary reasons: (1) in 1901, vast oil reserves were discovered in Texas; (2) in 1912, a viable electric starter for gasoline engines was introduced; and (3) Henry Ford decided to mass-produce gasoline-burning cars.
The internal-combustion engine operates during highway and cruise driving, when the engine is most efficient.
