Title: Environmentally friendly IC engine - has total expansion filling of fuel and oxygen ignited shortly before TDC
Inventor: DRZISGA HILARIUS DIPL ING
IPC: F02B1/04
Filed: 1991-07-31
Abstract: The engine has no inlet valve; only an exhaust valve (8) for each cylinder, and three inlet nozzles (9, 10, 11).
