ABSTRACT:
A control system is provided with a mass airflow sensor for sensing mass of intake air and for producing a mass airflow signal, an engine speed sensor for an engine speed signal proportional to the speed of the engine, and a throttle angle position sensor for producing a throttle angle signal representing the angle of the throttle valve. A first table is provided for storing first coefficients for characteristics of the injector, and a second table is provided for storing second coefficients for characteristics of the mass airflow sensor. Injection pulse width is calculated based on the mass airflow signal, engine speed signal, a read-out first coefficient and a read-out second coefficient which are dependent on the mass airflow-signal, the engine speed signal and the throttle angle signal.
