    摘要： The invention relates to a method for the determination of a rough road in a vehicle with a multi-cylinder internal combustion engine (1) mounted thereon. With a view to economically performing determination of a rough road with high accuracy, a revolution variance (IAC,VAC) is detected with respect to each cylinder in the internal combustion engine (1). Based on detection of revolution variance states, each of which indicates a deterioration in combustion, in plural cylinders, the vehicle with the internal combustion engine (1) mounted thereon is determined or estimated to be running on a rough road.

    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 combustion control system for a lean-burn engine, to be mounted on an automotive vehicle, uses probabilistic and statistical nature of combustion variance upon lean-burn operation to obtain reliable combustion control. The system detects a variance value in angular acceleration of a rotating member driven by the engine, normalizes the variance value in accordance with an operating state of the engine to determine a normalized variance value. The system also compares the normalized variance value with a predetermined threshold value to obtain a deteriorated combustion determining value. The system compares the deteriorated combustion determining value with a predetermined reference value and controls a combustion variance adjustment element so that the deteriorated combustion determining value matches the reference value.

    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： A controlling system for a vehicle-carried internal combustion engine which prevents the rotational speed of the engine from rising excessively high even when an accelerator pedal is operated in a condition of a power transmitting system wherein it does not transmit the driving force of the engine from a transmission to a wheel of the vehicle whether the vehicle is in a stopping condition or in a driving condition. Such condition of the power transmitting system is detected by a driving force transmitting condition detector, and when such condition is detected, a controller controls a throttle valve of the engine so that the opening of the throttle valve may not exceed a predetermined throttle opening greater than an idling throttle opening irrespective of an operation amount of the accelerator pedal.

    摘要： Throttle valves are individually disposed in a plurality of intake passages of an engine. In normal operation condition of the throttle valves, a first control device controls the throttle valves according to the detection result of an operation condition detecting device to control the amounts of intake air of the individual intake passages, thereby obtaining good engine performance from low-speed to high-speed ranges. When an abnormality detecting device detects an abnormality in a throttle valve, a determination device determines a normal throttle valve, and a second control device controls only the normal throttle valve in preference to the first control device to control the intake air amount, thereby ensuring continued operation even if a malfunction occurs in one of the throttle valves. Also, intake passages of the engine are divided into two systems and are individually connected with surge tanks, a communication passage communicating with the surge tanks and a communication control valve ae provided, throttle valves and intake control valves are disposed in the individual passages, and the throttle valves, the communication control valve and the intake control valves are open/closed controlled by the operation condition detecting device and control device, thereby obtaining good engine performance and ensuring continued operation of the engine even if a malfunction occurs in the throttle valve control system, to maintain the stability of the vehicle.

    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.
