Title:
筒内燃料噴射式エンジンの制御装置
Document Type and Number:
Japanese Patent JP3979506
Kind Code:
B2
Abstract:
A feed back control system and method for direct injected engines, particularly useful in marine applications to avoid excessive hunting due to the close proximity of the sensor to the fuel injector. Both injection initiation and duration are controlled under most operating conditions. However, under certain conditions such as when only small corrections in the air fuel ratio are required the control is initially maintained by adjusting the injection timing.
