    • 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.

    • A fuel supplying apparatus and method for supplying a cylinder of an internal combustion engine with fuel. An intake passage is connected to the cylinder for introducing air to the cylinder. An intake valve and an injector are provided in the intake passage. A throttle valve is positioned in the intake passage for adjusting the amount of air flow into the cylinder. An electronic control unit (ECU) controls the position of the throttle valve. The ECU controls the throttle valve to decrease the pressure in the intake passage when cranking is started. The ECU estimates the pressure adjacent to the intake port based on the engine speed and a time period measured from the start of cranking. The ECU also estimates what the intake port pressure will be when the intake valve is subsequently closed. The ECU computes an amount of fuel to be injected based on the pressure that was estimated based on a closed intake valve, and controls the injector to inject the computed amount of fuel.
