    摘要: Disclosed is an internal combustion engine control device capable of accurately achieving a target torque. At time t11, which precedes an exhaust stroke, a target throttle angle is calculated in accordance with the target torque. During a period between time t12 and time t13, the actual throttle angle is changed to match the target throttle angle calculated at time t11. At time t14 during a subsequent intake stroke, the target torque decreases. At time t18 during a subsequent compression stroke, a target ignition timing is calculated in accordance with the latest (decreased) target torque.

    摘要: A fuel injection timing control device for an internal combustion engine. The device comprises a fuel injector for injecting fuel into the intake port of an engine cylinder and an fuel injection end-timing control system for controlling the fuel injection end-timing of the fuel injector so as to advance gradually, from a first crank angle in the intake stroke to a second crank angle before the intake stroke, according to the engine operating condition. Accordingly, when the fuel injection timing is changed, the amount of fuel which sticks or adheres in the intake port is gradually increased by a small amount, at each fuel injection, so that the air-fuel ratio of the mixture does not become so lean the drivability of the vehicle is deteriorated.
