摘要： PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine suppressing more effectively occurrence of knocking by changing the closing timing of an intake valve in the control device for the internal combustion engine changing the closing timing of the intake valve for suppressing occurrence of knocking.
SOLUTION: This control device for the internal combustion engine changes the closing timing of the intake valve when occurrence of knocking must be suppressed, and the closing timing of the intake valve after changing is determined by taking pulsation of cylinder pressure into consideration. The closing timing of the intake valve is determined by taking pulsation of cylinder pressure into consideration as the present invention (step 109), thereby, for example, the closing timing of the intake valve after changing can avoid becoming timing increasing cylinder pressure by the influence of pulsation of cylinder pressure in comparison with the closing timing of the intake valve before changing. Thereby, occurrence of knocking is more effectively suppressed by changing the closing timing of the intake valve.

摘要： PROBLEM TO BE SOLVED: To inhibit generation of torque shock and also inhibit generation of knocking when engine operation is switched from full cylinder operation to cylinder cut-off operation in a variable cylinder internal combustion engine selectively performing the full cylinder operation and the cylinder cut-off operation.
SOLUTION: An ignition timing control device performs ignition timing control for delaying ignition timing when an air volume GA sucked into cylinders 2A, 2B increases. Until a predetermined period α elapses from when the engine operation is switched from the full cylinder operation to the cylinder cut-off operation, the ignition timing is advanced before the ignition timing set by the ignition timing control device.

摘要： PROBLEM TO BE SOLVED: To provide a new means capable of controlling the ignition timing of an internal combustion engine while allowing for the influence of heat losses.
SOLUTION: The amount of heat loss of an internal combustion engine is calculated and the ignition timing is controlled based on the amount of heat loss. When a heat loss rate RQ
W is 0%, a 50% combustion point during MBT is generally TDC (top dead center), and the heat loss rate RQ
W and the crank angle of the 50% combustion point during MBT are generally proportional to each other. Thus, to perform correction or setting of the ignition timing while allowing for the heat loss rate, at least one preliminary experiment is conducted for calculating the heat loss rate RQ
W and the 50% combustion point during MBT. Use of the amount of heat loss as a parameter facilitates correction or setting of the ignition timing.

摘要： PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine capable of accurately estimating possibility of an engine stall, and capable of surely preventing the engine stall without raising an engine speed than required.
SOLUTION: An average value and a standard deviation of a model parameter of Wiebe function model is estimated on the basis of operation conditions (step 110). A model parameter for each of cycles is extracted at random from a normal distribution regulated by the average value and the standard deviation, and thereby, indicated torque ITQ for 100 cycles is estimated based on Wiebe function model (step 120). When a minimum indicated torque ITQmin is smaller than a decision value ITQt, it is determined that there is the possibility of the engine stall (step 128), and the optimum throttle opening THAm whereby the engine stall is prevented, is retrieved.

摘要： PROBLEM TO BE SOLVED: To properly control ignition timing even when there is aged deterioration, and individual difference coming from a manufacturing error or the like. SOLUTION: An ignition timing correction amount is determined in response to a correlation value between a 50% burning point BP50[°ATDC] and torque ITQ. Since a correlation coefficient cor being lower than a reference value thrl which is a negative value means that the 50% burning point BP50 and the torque ITQ are distributed in a "descending" state as indicated by a sign (a), it can be estimated that the present ignition time is in a retardation side with respect to an MBT. Thus, in such a case, the ignition timing is corrected to a timing advance side. COPYRIGHT: (C)2007,JPO&INPIT
