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： 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.

摘要： A system and method for unthrottled intake air control for an internal combustion engine. The engine has at least one combustion chamber provided with electromagnetic intake means. The opening and closing times of the intake means are adjustable entirely independently from the crankshaft position to control intake air supplied to the combustion chamber. A control unit is used to implement instructions for determining a first portion of requested intake airflow, which first portion requests a first engine response performance, and instructions for determining a second portion of requested intake airflow, which second portion requests a second engine response performance. The control unit implements instructions for processing the first and second airflow portions to make contributions to the first and second engine response performances, respectively, instructions for determining an intake means activation command, and instructions for providing the intake means activation command to the intake means to provide an engine response performance combining the first engine response performance with the second engine response performance.

摘要： An engine with a charger, in which an intake passage is provided with a throttle valve which is electronically controlled to a target opening degree and the charger on the upstream side of the throttle valve, wherein a target supercharged pressure is corrected in a direction of eliminating a delay in the intake air amount based upon a difference between the target supercharged pressure of the charger and the supercharged pressure detected on the upstream side of the throttle valve, to thereby set a target supercharged pressure of the throttle valve based on the corrected target supercharged pressure. This suppresses a delay in the intake air amount caused by a delay in the change of the supercharged pressure during the transient period, makes it possible to accomplish acceleration/deceleration performance of good response, and suppresses a torque difference that occurs when the combustion system is changed over to the stratified charge combustion or to the homogeneous combustion.
