    • In step 400, microcomputer 12 calculates a temperature change amount ΔT1 of ignition coil FC caused by the heat generating from the ignition coil FC, based on a previous calculated temperature T(n−1) of ignition coil FC and an engine rotational speed. In step 410, the microcomputer 12 calculates a temperature change amount ΔT2 of ignition coil FC caused by the heat received from the engine, based on the previous calculated temperature T(n−1) of ignition coil FC and a cooling water temperature of the engine. In step 420, the microcomputer 12 calculates a temperature change amount ΔT3 of ignition coil FC caused by the heat released to the outside, based on the previous calculated temperature T(n−1) of ignition coil FC and an intake air temperature of the engine. Then, in step 430, the microcomputer 12 calculates a present ignition coil temperature T(n) based on these change amounts ΔT1, ΔT2, and ΔT3.

    • In a fuel injection control system for an internal combustion engine, a fuel atomization device is provided to atomize fuel injected at the time of engine starting. The fuel atomization device may be a type which increases fuel pressure to a higher value at the time of engine starting than after the engine starting. Alternatively, the fuel atomization device may be a type which supplies assist air to the injected fuel. An intake valve is opened for a longer period at the time of engine starting than after the engine starting, so that more fuel may be supplied to an engine cylinder. A fuel leakage which may occur during engine stop is estimated, and the amount of fuel to be injected at the time of next engine starting after the engine stop is corrected by the estimated amount of fuel leakage. Fuel injection timing at the time of engine starting is retarded relative to that of post-engine starting. The amount of injected fuel adhered to an intake port and not supplied into an engine cylinder after the closing of the intake valve is estimated, and the amount of fuel to be injected next is corrected thereby.

    • An oxygen concentration detecting apparatus precisely and easily performs diagnosis of a limit current type oxygen sensor. The limit current type oxygen sensor has an oxygen concentration detecting element for outputting limit current proportional to the oxygen concentration and a heater for heating the detecting element. A CPU of a microcomputer controls energization of the heater to activate the oxygen sensor. The CPU calculates element resistance based on the voltage applied to the oxygen sensor and the current detected in the sensor. In a sensor diagnosis routine, the CPU determines whether preconditions for the diagnosis have been met. If all the preconditions have been met, the CPU executes the diagnosis. That is, the CPU determines whether the element resistance is within a predetermined range. If it is below the range, the CPU determines that the sensor has high element temperature abnormality. If the element resistance is above the range, the CPU determines that the sensor has low element temperature abnormality.

    • A control unit uses upper and lower limit guard values to limit a power generation quantity of a power generator and thereby to maintain the current combustion mode during power generation of the power generator. The control unit computes a remaining electric charge of a battery. When the remaining electric charge drops to a predetermined value or below, the control unit cancels a combustion mode maintaining operation, which maintains the current combustion mode, is cancelled, so that priority is given to the power generation of the power generator to recover the remaining electric charge of the battery. Also, when an electric power consumption in a vehicle is equal to or greater than a predetermined value, the combustion mode maintaining operation is cancelled, and the power generation quantity of the power generator is controlled in a manner that does not cause overdischarge of the battery.
    • 控制单元使用上限和下限值来限制发电机的发电量,从而在发电机发电期间保持当前的燃烧模式。 控制单元计算电池的剩余电荷。 当剩余电量下降到预定值以下时,控制单元取消维持当前燃烧模式的燃烧模式保持操作被取消,从而优先考虑发电机的发电以恢复剩余电量 电池的电荷。 此外,当车辆的电力消耗等于或大于预定值时,消除燃烧模式保持操作,并且以不会导致电池过度放电的方式控制发电机的发电量 。
