Title:
内燃機関の燃焼過程を制御する方法と、エンジン弁を制御する手段を有する内燃機関
Document Type and Number:
Japanese Patent JP4478334
Kind Code:
B2
Abstract:
Four-stroke internal combustion engine with electrically operated inlet and exhaust valves (9,11) and means for supplying a homogeneous fuel/air mixture to the engine cylinders (1). The valves are controlled by a control unit (15), which, within a lower rpm range, closes the exhaust valve (11) before the piston (4) has reached its upper dead center point. Under the effect of trapped residual gas, a temperature increase is achieved, which results in compression ignition of the fuel/air mixture. The control unit (15) controls the exhaust valve (11), so that the amount of residual gases in the cylinders at the closing of the exhaust valves is greater at low loads and high rpm than at high loads and low rpm, in order to control the ignition delay in this manner.
