摘要： A torque variation in an internal combustion engine due to the combustion variations is detected at each predetermined period. An average torque variation to be compared with the detected torque variation is predetermined experimentally based on the engine speed and the intake manifold pressure and is stored in a memory. The number of the detected torque variations which exceed the average torque variation multiplied by a predetermined constant is counted, and if the ratio of the counted number to the total number of the detected torque variations is larger than a predetermined reference value, then the presence of a torque variation is determined.

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： In a method for measuring variations in the output of an internal combustion engine, at least one of signals respectively representing an engine speed, torque, and internal cylinder pressure of the internal combustion engine during the firing strokes of the engine is obtained. A periodical and pulsating change in the obtained signal is detected. A differential value at a portion of the change of the signal having a maximum gradient is then detected. Another method provides measuring variations in the output of the internal combustion engine by calculating the difference between the maximum and minimum values of the change of the obtained signal. Still another method provides measuring variations in the output of the internal combustion engine by correcting the obtained value in accordance with the engine speed. Still another method provides measuring variations in the output of the internal combustion engine by calculating the difference between consecutive changes.

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.
