INTERNAL COMBUSTION ENGINE Russian patent published in 2004 - IPC

FIELD: mechanical engineering; internal combustion engines.

SUBSTANCE: proposed engine has main combustion chamber, vortex antechamber in form of solid of revolution and connected with main chamber by channel, fuel nozzle installed in antechamber, and piston with shaped displacer on piston crown made of material with memorized shape effect. Iron and nicker-based allow can be used as such material. When engine is not warmed at partial loads said shaped displacer turns through some angle, thus providing swirling of air in antechamber.
