ALTERNATIVE ENGINES

ALTERNATIVE ENGINES

The most common type of alternative engine is the diesel engine, which instead of igniting the compressed fuel/air mixture with a spark, uses compression alone, heating the mixture to the point where it explodes.

A diesel engine's fuel consumption is low in comparison with similarly sized piston engines, despite its heavier, reinforced moving parts and cylinder block.

Another type of engine is the rotary combustion, first successfully developed bu Felix Wankel in the 1950s. Its two trilobate(three sided) rotors revolve in housings shaped.

The four sequences of the four -stroke cycle, which occur consecutively in a piston engine, occur simultaneously in a rotary engine, producing power in a continuous stream.
