The term internal combustion engine usually refers to an engine in which combustion is intermittent, such as the more familiar four-stroke and two-stroke piston engines, along with variants, such as the six-stroke piston engine and the Wankel rotary engine.
Four-stroke engine
Four-stroke engines are the most common internal combustion engine design for motorized land transport, being used in automobiles, trucks, diesel trains, light aircraft and motorcycles.

In 2007 the museum acquired a rare Griffin six-stroke gas engine, that had been in storage in Yeovil, Somerset, after having been moved from London in 2001.
Beare-head engine
The Beare-head engine internal combustion engine technology combines a four-stroke engine bottom end and piston, with a ported cylinder head closely resembling that of a two-stroke engine.
The Beare-head engine internal combustion engine technology combines a four-stroke engine bottom end and piston, with a ported cylinder head closely resembling that of a two-stroke engine.
This configuration has been described as a six-stroke engine based on adding together the four strokes per cycle of the bottom piston and the two strokes of the cylinder head piston, but there are essentially only 4 strokes, just with an alternative form of valving.

These operations are repeated cyclically and an engine is said to be 2-stroke, 4-stroke or 6-stroke depending on the number of strokes it takes to complete a cycle.

Stroke (engine)
A phase of the engine's cycle (e.g. compression stroke, exhaust stroke), during which the piston travels from top to bottom or vice versa.
