摘要： A control system controls an intake air quantity to an engine by controlling an intake valve closing timing, instead of, or in cooperation with, a throttle valve. A controller estimates a quantity of internal EGR gases remaining in a cylinder, and controls the intake valve closing timing to a desired target timing determined in due consideration of the estimated internal EGR quantity. The estimated internal EGR quantity is a sum of a base quantity and an increase correction quantity determined in accordance with a valve overlap period, its middle angular position in crankshaft rotation and intake pressure. The target intake valve closing timing is determined in accordance with a target intake air quantity and the estimated internal EGR quantity.

摘要： A control unit controls both a motor actuated throttle valve and a magnetically actuated variable valve in accordance with an operation condition of an internal combustion engine. The control unit is configured to provide both a first control mode wherein an intake air control is carried out by controlling the open/close timing of the variable valve while keeping the throttle valve at a full-open or near full-open position and a second control mode wherein the intake air control is carried out by controlling the position of the throttle valve while reducing a controllable range of the open/close timing of the variable valve. The first and second control modes are selectively switched in accordance with the operation condition of the engine. The first and second control modes allow the engine to output the same engine torque under the same operation condition of the engine. The first and second control modes are respectively provided by calculating target intake air amounts for the first and second control modes and feeding the engine with the calculated target intake air amounts respectively.

摘要： In a vehicle engine, when an accelerator pedal is released and a vehicle speed has decreased after fuel injection by a fuel injector has stopped, a controller restarts fuel injection. An engine rotation speed decrease rate immediately prior to restarting fuel injection is calculated, and a restart fuel injection amount is set which is larger the larger the decrease rate. In this way, the torque generated by the engine quickly recovers even during rapid deceleration, while during gradual deceleration, the generated torque increases gradually so that a torque shock does not occur.
