Beare Head
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 head piston is smaller and moves at half cycling of the bottom piston. Functionally, the cylinder-head piston replaces part of the valve mechanism of a conventional four-stroke engine, and protects the remainder from the higher pressures. This configuration has been described as a six-stroke engine The term six-stroke engine has been applied to a number of alternative internal combustion engine designs that attempt to improve on traditional two-stroke and four-stroke engines. Claimed advantages may include increased fuel efficiency, reduced m ... 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.

Internal Combustion Engine
An internal combustion engine (ICE or IC engine) is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high-temperature and high-pressure gases produced by combustion applies direct force to some component of the engine. The force is typically applied to pistons ( piston engine), turbine blades (gas turbine), a rotor (Wankel engine), or a nozzle ( jet engine). This force moves the component over a distance, transforming chemical energy into kinetic energy which is used to propel, move or power whatever the engine is attached to. This replaced the external combustion engine for applications where the weight or size of an engine was more important. The first commercially successful internal combustion engine was created by Étienne Lenoir around 1860, and the first modern internal combustion engine, known ...
