    摘要： An air-fuel ratio control method controls the air-fuel ratio of an air-fuel mixture supplied to an internal combustion engine having spark plugs, and heaters for heating the air-fuel mixture in the vicinity of respective ones of the heaters, the air-fuel mixture containing a fuel which is poor in atomizing characteristic at a low temperature. The method comprises the steps of (1) determining whether or not a temperature of the engine is lower than a predetermined value, (2) determining whether or not the engine is being cranked, (3) detecting an amount of electric current flowing through each of the heaters, and (4) controlling an amount of fuel supplied to the engine based on the detected amount of electric current when it is determined that the temperature of the engine is lower than the predetermined value and at the same time the engine is being cranked.

    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： 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.

    摘要翻译： 一种用于控制安装在火花塞上的加热器的系统，该火花塞点燃内燃室的燃烧室中的空气燃料混合物。 加热器开启时间被确定为随着发动机温度的升高和酒精浓度的增加而减小。 供应给加热器的电流也被确定为随着酒精浓度的增加而增加，并随着发动机温度的升高而降低。 因此，可以除去高酒精浓度燃料引起的火花塞处的液滴，同时消除碳污染。 因此可以改善发动机的起动性，而不会使火花塞的使用寿命短暂。 此外，燃料喷射量减少，从而不会将另外的燃料沉积在仍然存在的液滴燃料上。 此外，当起动电动机转动以向电动机提供足够的动力时，加热器进一步保持关闭。

    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： A light source device including a short arc discharge lamp having a pair of opposed electrodes within a light emitting bulb of a discharge container, and a concave reflector having an optical axis arranged to coincide with a direction of an arc produced by the electrodes when the discharge lamp is activated. The electrodes are spaced from each other at a distance of 4.0 mm or less and the light emitting bulb has an inner surface and an outer surface which, at least in a specific portion, have substantially spherical surfaces with a center of curvature which is at a center of the arc. The specific portion is located in front of a critical line that passes through the light emitting bulb, the specific portion being an angle having an apex at the center of the arc. The concave reflector has an optical axis that is at least 3 sr in front of a plane which passes through the center of the arc and perpendicular to the optical axis of the concave reflector.
