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： An evaporative emission control system for an internal combustion engine controls purging of evaporative fuel into the intake pipe of the engine. A first control valve is arranged in a communication passage communicating between a charcoal canister and the intake pipe, for supplying the evaporative fuel to the engine at a flow rate dependent on load on the engine. A second control valve is arranged in a bypass passage bypassing the first control valve for supplying the evaporative fuel to the engine at a predetermined flow rate. When a temperature of the engine is below a predetermined value, the first control valve is closed and at the same time the second control valve is made open, to thereby supply the evaporative fuel to the engine at the predetermined i.e. small flow rate. For a predetermined time period after the engine has been warmed up, the first and second control valves are controlled in the same manner. When the engine is idling as well, the same control of the two valves is carried out.

摘要： A air-fuel control system for internal combustion engines using a blended fuel composed of gasoline and alcohol for determining or presuming a correction factor due to alcohol concentration in the fuel when an alcohol sensor for detecting the same has failed. An average value of the O.sub.2 feedback correction factor reflecting a deviation between a target air fuel ratio and an actual air-fuel ratio is obtained and based on it, a target value is determined. The average value is compared with upper and lower limits and when it reaches either one, the factor obtained when the sensor operated properly is adjusted by an amount to follow up the target value.

摘要： In an evaporative fuel control system in an internal combustion engine, a purge gas concentration is estimated by a purge gas concentration estimating device based on an air-fuel ratio correcting factor provided when a purge control valve is in its opened state and an air-fuel ratio correcting factor provided when the purge control valve is in its closed state. A lower limit value of an air-fuel ratio correcting factor, set by an air-fuel ratio correcting factor setting device, is determined by an air-fuel ratio correcting factor limit value setting device in accordance with the purge gas concentration estimated by the purge gas concentration estimating device. Thus, the lower limit value of the air-fuel ratio correcting factor can be varied depending upon the concentration of the purge gas, thereby setting an air-fuel ratio control range corresponding to the concentration of the purge gas.

摘要： A system for controlling an air/fuel ratio of an internal combustion engine supplied with a blended fuel of gasoline and alcohol and equipped with a blowby gas ventilator. An oxygen sensor is provided and an amount of fuel supply is corrected in response to the detected air/fuel ratio within a range having a lower limit set in the lean direction and an upper limit set in the rich direction. At engine starting, injected alcohol may not vaporize but leak into the crankcase and will then vaporize to pass into the air intake passage along with the blowby gas when the engine temperature rises, causing the air/fuel ratio to be become rich beyond the correction lower limit. For that reason, in this system, engine coolant temperature and alcohol content in the fuel are detected. And if the temperature is within a range defined from the alcohol boiling point when the alcohol content is above a reference value, the lower limit of the range is shifted in the leaner direction. The air/fuel ratio can therefore be corrected in the lean direction.
摘要翻译：一种用于控制供给汽油和酒精的混合燃料并装备有窜气通气机的内燃机的空燃比的系统。提供氧传感器，并且响应于在倾斜方向上设定的下限和在富方向上设定的上限的范围内的检测到的空气/燃料比来校正燃料供应量。在发动机启动时，注入的醇可能不会蒸发，但会泄漏到曲轴箱中，然后随着发动机温度升高时的排气气体会蒸发进入进气通道，导致空气/燃油比变得超过校正值限制。因此，在该系统中，检测到燃料中的发动机冷却剂温度和酒精含量。而当酒精含量高于参考值时，如果温度在从醇沸点定义的范围内，则该范围的下限在较冷的方向上移动。因此，可以在倾斜方向上校正空气/燃料比。
