摘要： PROBLEM TO BE SOLVED: To operate an internal combustion engine so that a combustion state without output fluctuation and with stability is maintained in a cold condition, in a control system for an internal combustion engine comprising a variable valve system capable of varying operation timing of an intake valve.
SOLUTION: The variable valve system is provided to vary valve closing timing of the intake valve. In a cold operation of the internal combustion engine (Step 100), if a misfire is detected (Step 110), a target compression ratio tε is increased (Step 112), or if knocking is detected, the target compression ratio tε is decreased (Step 114). Target valve closing timing tIVC of the intake valve for realizing the target compression ratio tε is computed (Step 116). A maximum lift IVLMax and valve opening timing IVO of the intake valve are decided so as to bring an intake air quantity GN at a desired value while realizing the target valve closing timing tIVC (Step 120).

摘要： PROBLEM TO BE SOLVED: To suppress knocking. SOLUTION: A valve-lift changer 9 is provided for changing an opening area of an intake valve 2. When knocking occurs, the valve-lift changer 9 is used to reduce the operating angle of the intake valve 2 and increase the opening area of the intake valve 2. Otherwise, when the knocking occurs, the valve- lift changer 9 is used to reduce the opening area of the intake valve 2. Otherwise, when the knocking occurs, the valve-lift changer 9 is used to reduce the operating angle of the intake valve 2 and increase the opening of a throttle valve or an idling speed control valve.

摘要： PURPOSE:To reduce HC, CO in exhaust gas while obtaining good responsiveness even at engine cold time and even except at the cold time. CONSTITUTION:Fuel is injected from a fuel injection valve 12 in a period of opening an intake valve 5 at engine cold time. In this way, most of injection fuels flow into a combustion chamber 4. Here, an air pump 18 is turned on to supply secondary air into an exhaust pipe 15. In this way, HC, CO are purified in a catalyst 16. At except the engine cold time, fuel is injected from the fuel injection valve 12 before opening the intake valve 5. Since a wall surface or the like of an air intake port 6 is fully at a high temperature, injection fuel is almost atomized to flow into the combustion chamber when the intake valve 5 is opened. Here since there is almost no HC, CO, the air pump 18 is stopped.

摘要： PROBLEM TO BE SOLVED: To enhance the effect of an engine brake. SOLUTION: The valve opening property of an intake valve 2 is controlled so that the valve lifting amount of the intake valve 2 becomes a peak when a crank angle reaches a predetermined value. Preferably, the intake valve opening property is controlled so that the intake valve lifting amount becomes the peak at a certain point during the period from the point prior to a piston fastest point by that corresponding to 30 degrees of a crank angle to the point after the piston fastest point by the above corresponding point, most preferably at the piston fastest point.

摘要： PROBLEM TO BE SOLVED: To reliably prevent a torque shock in an operation controller having a control mechanism for changing the valve opening and closing timing of an intake valve or an exhaust valve and the valve opening amount. SOLUTION: This operation controller for an internal combustion engine is provided with a transmission 60 for controlling the gear ratio, and an intake valve control mechanism for controlling the valve opening and closing timing and the valve opening amount of an intake valve 3. When the gear ratio is changed by the transmission, at least one target value of the valve opening and closing timing or the valve opening amount of the intake valve is changed by the intake valve control mechanism. The change amount of the valve opening and closing timing or the valve opening amount of the intake valve, to be changed by the intake valve control mechanism when the gear ratio is changed by the transmission is corrected according to the state related to the intake valve control mechanism.

摘要： PROBLEM TO BE SOLVED: To control drop in engine speed, accompanying the change-over of an automatic transmission from a non-driving range to a driving range. SOLUTION: Variable valve systems 9, 11 for changing the valve opening characteristic of at least one valve of an inlet valve 2 and an exhaust valve 3 and the an automatic transmission 22 are installed. When the automatic transmission 22 is changed over from the non-driving range to the driving range, the valve-opening characteristic of at least either valve of the inlet valve 2 or the exhaust valve 3 is changed, so as to increase engine output torque by the variable valve systems 9, 11. For example, the valve lift amount and the working angle of the inlet valve 2 are increased.

摘要： PROBLEM TO BE SOLVED: To keep an idling speed of an engine stable, even when the load of accessories increases. SOLUTION: The idling speed control device for an internal combustion engine keeps the idling speed of the internal combustion engine at a target speed. The internal combustion engine drives the accessories. The idling speed control device comprises a load detecting means for detecting the load of the accessories; and a correction amount setting means (steps S2 to S7) in which a correction amount for controlled variables to keep the idling speed at the target speed is set based on a degree of the load detected by the load detecting means and a degree of delay in response depending on the degree of the load.

SOLUTION: In the internal combustion engine with an intake throttle valve in an engine intake pathway, it is judged whether the vaporization of fuel injected from a fuel injection valve should be promoted or not. When it is judged that the vaporization of fuel should be promoted, the opening reducing process is executed to reduce the opening of the intake throttle valve 15.
