Air intake method and controller for engines performing stratified charge combustion |
摘要 |
An engine having an air intake passage for drawing air into a combustion chamber and an injecting device for injecting fuel into the combustion chamber. A mixture of air and fuel undergoes stratified charge combustion. Sensors detect the operating conditions of the engine, and a swirl control valve opens and closes the air intake passage to swirl the air-fuel mixture. An actuator drives the swirl control valve. A computer computes a target opening angle of the swirl control valve in response to the detected operating conditions. A controller controls the force of the swirl by controlling the actuator in accordance with the computed target opening angle. A detector detects fluctuation of engine rotation. A corrector corrects the target opening angle in response to the detected fluctuation of the engine rotation to improve the performance of the engine.
