摘要： If it is determined that an engine has been started, an engine coolant temperature is detected. If the engine coolant temperature is equal to or lower than a threshold value, the catalyst quick warm-up control is started to retard ignition timing, and a signal indicating a command to increase an operate angle is transmitted to a VVLA controller. When a VVT hydraulic pressure is increased to a predetermined value, a signal indicating a command to decrease the operate angle is transmitted to the VVLA controller, and a signal indicating a command to advance open timing of an intake valve is transmitted to a VVT controller so that the open timing of the intake valve is not changed. If the engine coolant temperature is equal to or higher than a threshold value, the catalyst quick warm-up control ends, and the ignition timing is returned to normal timing.

摘要： A fuel injection mode is flexibly controlled according to the actual extent of adverse effects on an internal combustion engine from both deterioration of exhaust gas emissions and fuel dilution caused by fuel adhering to the piston top face and the cylinder inner peripheral face. A dilution degree counter value C is counted up when a coolant temperature at engine startup THWST and an intake air quantity sum value after engine startup GASUM are each equal to, or less than, respective predetermined values. A fuel dilution flag is set to “ON” when the dilution degree counter value C is equal to, or greater than, a predetermined value CH. A fuel injection timing of an intake stroke injection is changed to a timing on the advance side when this fuel dilution flag is “ON.”

摘要： After an elapse of a predetermined time period or after a run of a predetermined distance, a power output system of the present invention heats a catalytic converter with a catalyst heater while enabling an engine to be driven under a driving condition suitable for checking a catalyst packed in the catalytic converter for deterioration of the catalytic function. The power output system then measures a variation in temperature of the catalyst in this state and determines whether or not the variation is within a normal range, thereby detecting the deteriorating catalytic function of the catalyst, that is, abnormality of the catalytic converter. This structure enables the power output system to realize accurate detection of abnormality of the catalytic converter at a sufficient frequency. During the measurement of the temperature change of the catalyst, an assist motor is driven and controlled to output a torque Td* corresponding to a step-on amount of an accelerator pedal to a drive shaft. This enables a desired power to be output to the drive shaft even during the course of the abnormality detection. Detection of abnormalities in an engine supercharger and exhaust gas recirculation system is also provided.

摘要： In an internal combustion engine of a hybrid vehicle, a transient driving state occurs at a high frequency. It is rather difficult to control the quantity of fuel due to an adhesion of the fuel on the wall surface in the transient driving state. This results in insufficient reduction of the emission in the transient driving state. The object is thus to provide a vehicle control apparatus that can realize the effective reduction of emission. The vehicle control apparatus receives vehicle information (S200) and determines, based on the input vehicle information, whether or not the state of the vehicle should be shifted from either a combination mode or an internal combustion engine mode to a motor mode, that is, whether or not operation of an internal combustion engine EG is going to stop (S202). When such a mode shift is required, it is determined whether or not a specific warm-up condition is satisfied (S204). The specific warm-up condition is used as a criterion for determining whether or not a fuel-air intake system of the internal combustion engine EG shows a sufficient increase in temperature based on the data of a cooling water temperature sensor and reaches a stationary state, wherein the amount of fuel injected and supplied into the fuel-air intake system and adhering to the wall surface can be estimated readily. When it is determined that the specific warm-up condition is satisfied, the program exits from the routine. When it is determined that the specific warm-up condition is not fulfilled, on the other hand, a table correction process is carried out (S206) to modify the contents of a mode selection table and change the motor mode to the combination mode.

摘要： An engine has a variable valve actuation mechanism that varies lift characteristics of an intake valve. An idle speed control apparatus has a control section for controlling an intake air amount of the engine in an idle state for adjusting an actual engine speed to a target engine speed. The control section sets a control amount related to control of the intake air amount in correspondence with the lift characteristics, which are varied by the variable valve actuation mechanism. Accordingly, the engine speed in the idle state is effectively controlled in correspondence with changes of the lift characteristics.
