摘要： A control mode of an intake valve lift controller is changed between a low-speed mode and a high-speed mode. Based on the control mode, an ignition timing is adjusted. When a knocking is detected by a knock sensor after the control mode is changed from the low-speed mode to the high-speed mode, it is determined that the intake valve lift controller has a malfunction in which the intake valve lift controller is stuck in the low-speed mode. When a combustion stability is lowered to a predetermined level after the control mode is changed from the high-speed mode to the low-speed mode, it is determined that the intake valve lift controller has a malfunction in which the intake valve lift controller is stuck in the high-speed mode.

摘要： An intake apparatus for an internal combustion engine that has a first intake passage communicating with a combustion chamber of the internal combustion engine; a second intake passage which communicates with the combustion chamber of the internal combustion engine and whose length is greater than a length of the first intake passage; a valve for selectively changing over the communication/shutting off of the combustion chamber of the internal combustion engine with/from between the first or/and second intake passages; and a drive circuit for driving the valve to effect the changing over operation. A controller controls the drive circuit, and an air cleaner device introduces clean air into the combustion chamber of the internal combustion engine. The first and second intake passages are disposed inside a case of the air cleaner device, and the valve is disposed at a position which is prevented from interfering the outlet side of the second intake passage when the first intake passage is closed by the valve and the second intake passage is opened by the valve.

摘要： In an internal combustion engine, a plurality of engine rotational speeds are detected at predetermined timings for every firing stroke in one cylinder of the engine, and an engine speed variation is calculated as a variation between the square of one of the engine rotational speed and the square of another of the engine rotational speed. A process is performed upon the sequence of the engine speed variations, thus determining an engine combustion state by the processed result.

摘要： A torque detector for detecting a torque applied to a torque transmission shaft which is connected to a load such as a wheel of an automobile. A first rotating body is connected to one end of a driving shaft of an engine coaxially, and an annular second rotating body is disposed around a boss which projects from the center of the first rotating body so as to be coaxial and parallel with the first rotating body. An elastic member connects the inner peripheral portion of the second rotating body to the boss in the radial direction. The angular phase difference between the first and the second rotating bodies which occurs due to the deformation of the elastic member is detected, and torque is calculated from the obtained angular phase difference.

摘要： In an internal combustion engine, a standard deviation of combustion variations generated for every firing stroke of at least one cylinder is calculated. The misfire limit of the engine is detected by determining whether or not the calculated standard deviation is greater than a reference value. When the calculated standard deviation is greater than the reference value, the controlled air-fuel ratio is decreased, while when the calculated standard deviation is not greater than the reference value, the controlled air-fuel ratio is increased, thereby attaining a lean burn system without a lean mixture sensor.

摘要： In an air-fuel ratio control device, a torque detector for detecting torque variations which indicate combustion variations in an engine is mounted at the supporting portions of the internal combustion engine. A detecting signal from the torque detector is introduced into an electronic control unit which controls the amount of injecting fuel, namely the air-fuel ratio. The electronic control unit controls the air-fuel ratio toward the lean side by the signal from the torque detector so that the combustion variations (torque variations) in the engine does not become large.

摘要： A gas flow measuring device has a measuring circuit for measuring the flow of gas based on the output signals of an electric heater and a first and a second temperature dependent resistor. In the measuring circuit, the first and the second temperature dependent resistors, together with first and second reference resistors, form a bridge and a constant voltage is applied to a voltage at one diametrical point of the bridge. The difference between the other voltage of the diametrical point of the bridge and the output of the constant voltage adding circuit is amplified, and the output voltage of the amplifier circuit is further amplified so that the voltage applied to the electric heater and the bridge is feed-back controlled.
