Title:
INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JP2014206174
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To solve a problem in a conventional reciprocation engine.SOLUTION: An internal combustion engine is provided. Facing pistons eliminate a cylinder head, thereby reducing heat losses through a cylinder head. As facing pistons also halve the stroke that would be required for one piston to provide the same compression ratio, the engine can be run at higher revolutions per minute and produce more power. An internal sleeve valve is provided for space and other considerations. A combustion chamber size-varying mechanism allows adjustment of the minimum size of an internal volume to increase efficiency at partial-power operation. A variable intake valve operation is used to control engine power.
