New Fuel Injection Method for Better Driveability 880420
In our new fuel injection method, the injector for each cylinder is triggered twice per combustion cycle. The first injection is triggered as early as possible to obtain a good fuel mixture quality. The second injection is triggered as late as possible and as close to the intake valve opening so as to obtain a constant air-fuel ratio even during rapid acceleration.
Furthermore, in order to prevent, misfire, timing is calculated based on the fuel amount when the fuel injection occurs.
Driveability is improved over a wider range of driving conditions while maintaining good fuel economy and omission control.
