摘要： In a combustion control device for an internal combustion engine provided with a plurality of fuel injection modes having different target air-fuel ratios, threshold values for detecting deterioration of combustion in the internal combustion engine are determined separately for each fuel injection mode depending on features of variation of combustion in the internal combustion engine in each fuel injection mode. Quantity of variation of combustion in the internal combustion engine is, for example, detected in the form of revolution angular acceleration or revolution angular acceleration deviation of the engine. The detected quantity of revolution fluctuation is compared with a threshold value in the currently chosen fuel injection mode. Thus, deterioration of combustion is surely judged according to each fuel injection mode. In particular, threshold values in a compression stroke injection mode are determined to be larger than threshold values in an intake stroke injection mode. A threshold value in the compression stroke injection mode is so determined as to substantively correspond to a complete misfire state of the engine, and threshold values in the intake stroke injection mode consist of a first threshold value substantively corresponding to a complete misfire state of the engine and a second threshold value substantively corresponding to an unstable combustion state of the engine.
摘要翻译：在具有不同目标空燃比的多个燃料喷射模式的内燃机的燃烧控制装置中，根据燃料喷射模式的特征，分别确定用于检测内燃机的燃烧劣化的阈值在每种燃料喷射模式中内燃机的燃烧变化。例如，以内燃机的转角角加速度或回转角加速度偏差的形式检测内燃机的燃烧变化量。将检测到的转速波动与当前选择的燃料喷射模式中的阈值进行比较。因此，根据各燃料喷射模式可靠地判断燃烧的劣化。特别地，压缩冲程喷射模式中的阈值被确定为大于进气冲程喷射模式中的阈值。压缩冲程喷射模式中的阈值被确定为实质上对应于发动机的完全失火状态，并且进气冲程喷射模式中的阈值由实质上对应于发动机的完全失火状态的第一阈值组成以及实质上对应于发动机的不稳定燃烧状态的第二阈值。

摘要： An engine control unit of a control apparatus for an in-cylinder injection internal combustion engine sets a fuel injection timing for a compression-stroke injection mode in accordance with a fuel injection quantity, and corrects the fuel injection timing according to an engine cooling water temperature. When the cooling water temperature is lower than a temperature observed when a warm-up operation is completed, the fuel injection timing for the compression-stroke injection mode is corrected for advance or retard on the basis of the engine characteristic proper, and fuel is injected at an appropriate time such that the fuel evaporation rate and the fuel stratification degree which permit the stabilized combustion of the fuel injected into the combustion chamber are attained, whereby the fuel is evaporated satisfactorily. Thus, the occurrence of misfire and the emission of harmful gas components can be restrained effectively during the warm-up operation in the compression-stroke injection mode.

摘要： A valve moving control apparatus for an internal combustion engine comprising a control device for switching at least one valve by controlling a driving condition of an intake/exhaust valve, a load detecting device, a switch control device for outputting a switch signal to the control device, and a gear shift detecting device. The gear shift detecting device detects whether a gear is shifted to a relatively low gear in a gearbox. If the gear is shifted to a relatively low gear, a switching point for switching an actuation of the valve is shifted to a low load side in order to reduce torque shock caused by switching.

摘要： Disclosed is an automobile engine which has different ranges for the partial cylinder operation mode depending upon whether or not the engine is idling. The partial cylinder operation mode is selectable in different operation ranges in response to operating status of an air-conditioner, a power steering switch or a throttle opening sensor. Thus, the engine can reliably assume the partial cylinder operation mode in a wide operation range without stall, thereby accomplishing fuel saving.

摘要： In a fuel blending ratio detecting method, a first blending ratio of the methanol in the fuel supplied to an internal combustion engine is detected by a blending ratio sensor; an air/fuel ratio feedback compensation coefficient computed on the basis of an output of an O.sub.2 sensor is used to compute a feedback learned value, and the current blending ratio compensation coefficient is multiplied by this value to compute the next blending ratio compensation coefficient so as to obtain a second blending ratio; the current blending ratio compensation coefficient is multiplied by a peak mean value of the computed feedback compensation coefficient to compute the next blending ratio compensation coefficient so as to obtain a third blending ratio; and the first, second or third blending ratio is selected according to the operating conditions of the internal combustion engine. Thus, the selected blending ratio is always used as the control blending ratio very close to the true ratio, so that the internal combustion engine can be accurately controlled.
