摘要： An abnormal combustion-detecting device and a combustion control device for internal combustion engines. Ignition timing for the cylinders is set in accordance with engine operating conditions. The set ignition timing for at least one of the cylinders is retarded when the engine is in a predetermined operating condition. Abnormal combustion caused by postignition within the at least one cylinder is detected when the set ignition timing is retarded. When abnormal combustion is detected within the at least one cylinder, temperature within the cylinders is lowered, thereby positively preventing possible occurrence of preignition.

摘要： A system according to the invention controls the vaporized amount of a blended fuel composed of gasoline and an alcohol such as methanol and contained in a fuel tank mounted at a vehicular internal combustion engine. The methanol concentration in the fuel is sensed and from the sensed value, reid vapor pressure of the fuel is presumed. The pressure in the fuel tank is then regulated at a target pressure by adjusting the amount of vaporized fuel to be removed from the fuel tank and fed to a canister in response to the presumed reid vapor pressure.

摘要： An air-fuel ratio control system for an internal combustion engine using an alcohol blended fuel, in which an alcohol concentration-dependent correction coefficient for use in calculating an amount of fuel supplied to the engine is calcuated in response to concentration of alcohol in the fuel defected by an alcohol concentration sensor. An average value of the correction coefficient is calcuated depending on operating conditions of the engine. The amount of fuel supplied to the engine is calculated by the use of the average value of the correction coefficient to thereby control the air-fuel ratio of an air-fuel mixture supplied to the engine.

摘要： A system for controlling heater mounted on a spark plug which ignites the air-fuel mixture in the combustion chamber of an internal combustion chamber. The heater-on time is determined such that it decreases with increasing engine temperature and increasing alcohol concentration. Current supplied to the heater is also determined such that it increases with increasing alcohol concentration and decreases with increasing engine temperature. Therefore, droplets at the spark plug caused by high alcohol concentration fuel can be removed while eliminating carbon fouling. The engine startablity can thus been improved without shorting the service life of the spark plug. Moreover, fuel injection amount is reduced so as not another fuel be deposited on a droplet fuel which is still being present. The heater is furthermore kept off when a starter motor is turning to supply sufficient power to the motor.

摘要： A hybrid vehicle control apparatus is provided, wherein an unpleasant sensation is not imparted to a driver depressing an accelerator pedal at the time of departure. In a hybrid vehicle control apparatus with an engine and a motor as the drive sources, and a battery for storing electrical energy from the engine or the kinetic energy of the vehicle converted by the motor, the vehicle is provided with an automatic transmission. Moreover, there is provided a discharge suppression mode which suppresses discharge from the remaining battery charge detected by a battery ECU, and a charge/discharge permit mode which permits charge/discharge of the battery. At a time of vehicle departure, departure assistance is performed only when a degree of throttle opening showing an acceleration intention of the driver exceeds a determination threshold which is larger than a determination threshold for at the time of the discharge/charge permit mode.
