摘要： A control device of a lean-burn engine has an electronic control unit. Upon start of switching from stoichiometric driving to lean driving, the control unit (10) derives, from a map, a target pressure (P0) and a basic opening degree (D0) of an idling speed control valve, serving as an air bypass valve, based on the throttle opening degree (TPS) and the engine rotation speed (Ne) at the start of the switching. The control unit supplies driving pulses (N) of a number corresponding to the basic opening degree (D0) to a stepper motor (32) of the idling speed control valve. Then, the control unit supplies the stepper motor with driving pulses of a number corresponding to an opening degree correction amount (D1) which in turn corresponds to a deviation between the target intake pressure (P0) and an actual intake pressure (PB), to thereby suppress a change in the torque at the time of switching between the rich driving, including the stoichiometric driving, and the lean driving of the lean-burn engine.

摘要： A control device for an internal combustion engine detects the air fuel ratio of the internal combustion engine at a condition with high accuracy and responsibility. Accordingly, improvement of the fuel consumption of the engine, improvement of the power of the engine, and improvement of the exhaust gas are achieved. The control device for an internal combustion engine calculates, in turn, a first air fuel ratio based on the fuel injection suction, a second air fuel ratio at the time when the gas is reached to the large area air fuel ratio sensor, and a third air fuel ratio at the time when the large area air fuel ratio sensor detects the air fuel ratio, according to the fuel amount calculated with respect to the difference between the sensed air fuel ratio and the objective air fuel ratio, to judge a jam of the large area air fuel ratio sensor by comparing the third air fuel ratio with the sensed air fuel ratio. Thus, the jam judgment is carried out in consideration with the fuel transportation lag, the transportation lag of the gas, and the response delay inherent to the large area air fuel ratio sensor. Accordingly, a highly accurate control for the air fuel ratio can be achieved.

摘要： This invention relates to an engine fuel injection timing control apparatus for controlling a fuel injection timing by adjusting the position of a timer piston via a solenoid valve. In this apparatus, a frequency signal switching means (44) selectively outputs a first frequency signal (W1) and a second frequency signal (W2) having a frequency lower than the first frequency signal (W1) according to an engine speed (Ne) detected by an engine rotational speed detecting means (49) with reference to preset signal switching engine rotational speeds (N.sub.1, N.sub.2, N.sub.3, N.sub.4, N.sub.5). With a driving frequency based on thus outputted frequency signal, a control means (46) duty-controls a timer controlling solenoid valve (39) according to an engine operation state. Here, the signal switching engine rotational speeds (N.sub.1, N.sub.2, N.sub.3, N.sub.4, N.sub.5) are set to levels which yield first predetermined rotational speed differences (U.sub.1, U.sub.2, U.sub.3, U.sub.4, U.sub.5) from engine rotational speeds where the resonance is generated with respect to a first frequency (f.sub.1) and second predetermined rotational speed differences (L.sub.1, L.sub.2, L.sub.3, L.sub.4, L.sub.5) from engine rotational speeds where the resonance is generated with respect to a second frequency (f.sub.2). Consequently, the fluctuation phenomenon of the timer piston can securely be suppressed in the vicinity of resonance points.

摘要： A control apparatus of an internal combustion engine includes an electronic control unit which determines whether a throttle valve opening sensor is normal or faulty in accordance with an output from the sensor. If the throttle valve opening sensor operates normally, a target air-fuel ratio is set in accordance with the output of the sensor. On the other hand, if the throttle valve opening sensor is in trouble, the control unit sets the target air-fuel ratio to a ratio equal to or close to the stoichiometric air-fuel ratio in accordance with the output of an intake air amount sensor, whereby a stable operation of the internal combustion engine is ensured.
