ABSTRACT:
A two-cycle engine has a fuel injector provided for injecting fuel directly in a cylinder of the engine. An amount of air actually induced into the cylinder is calculated based on the amount of escape air and the amount of intake air detected by an air-flow meter. The quantity of fuel injected by the fuel injector is calculated based on the engine speed and the amount of air induced in the cylinder. The timing of the fuel injection is advanced as engine load increases and the duration of fuel injection increases as the engine load and engine speed increase.
