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 certain conditions such as lean burn, steady state and transition from rich to lean the control is initially of only one of these two factors. If the air fuel ratio is then still out of range, the other control is effected.
