ABSTRACT:
A apparatus and method for adjusting the amount of air introduced into a cylinder of an internal combustion engine. An intake passage is connected to the cylinder for introducing air. An intake valve is provided in the intake passage for cyclically opening and closing the cylinder. An injector is provided in the intake passage for injecting fuel. A throttle valve is positioned in the intake passage for adjusting an amount of air flow into the cylinder. An electronic control unit (ECU) controls the position of the throttle valve. The ECU closes the intake passage to decrease the pressure in the intake passage when cranking is started. The ECU moves the throttle valve to a first open position .theta.2 to increase the amount of air introduced into the cylinder after a predetermined time period elapses from the start of engine cranking. The ECU moves the throttle valve to an open position .theta.1 when the engine starts.
