摘要： Fuel is injected in synchronism with the crank angle. In addition, an engine acceleration state is detected from the second-order differential value of the intake-pipe pressure, and the quantity of the asynchronous fuel injection in which fuel is injected in asynchronism with the crank angle is increased in an early stage of acceleration but is decreased after the early stage of acceleration. Moreover, no asynchronous injection is carried out in a low engine speed region. It is thereby possible to obtain an optimum air-fuel ratio in accordance with the engine acceleration state.
