Abstract: A lean burn internal combustion engine has a basic fuel injection amount calculated and multiplied by a lean correction factor, the resulting amount controls the air fuel ratio of the engine. The lean correction multiplied by factor is calculated from a first map based on intake pressure and engine speed. However, when the degree of opening of the throttle valve is larger than a predetermined value, a second correction map based on the degree of opening of the throttle valve and engine speed is used to obtain the lean correction factor. When the second correction map is employed, an ignition timing map based on the degree of opening of the throttle valve and engine speed is used to obtain an ignition timing; instead of the usual ignition timing, based on intake pressure and engine speed.

Abstract: An air-fuel ratio control device for an engine, by which the air-fuel ratio of the air-fuel mixture supplied to the engine is changed. The device set the air-fuel ratio to a lean mixture when the engine load is lower than a set load value and predetermined set speed, and when the engine load become higher than the set load value, or the engine speed exceeds the set speed, the device switches the air-fuel ratio from a lean mixture to a rich mixture to obtain higher engine output. The set load value is varied in accordance with the engine speed such that it is reduced as the engine speed is increased.

Abstract: In an internal combustion engine, a vibration period and a vibration amplitude are measured and the detected vibration period is compared with a natural vibration period prestored in accordance with a driving condition of the vehicle. If the detected vibration period is equal to the natural vibration period under the driving condition at which the vibration period is detected, it is determined that surging due to a torque variation of the engine is occurring. In this condition, the torque variation is controlled to be a predetermined value by increasing an air-fuel ratio or decreasing an amount of EGR when the detected vibration amplitude is smaller than a predetermined value, and the torque variation is controlled to a predetermined value by decreasing an air-fuel ratio or increasing an amount of EGR when the detected vibration amplitude is larger than a predetermined value, and accordingly, the driveability and emission rate are improved.

A determination of the activated condition of the oxygen sensor is obtained when the output level from the oxygen once exceeds the higher first level, or when the output level from the oxygen sensor consecutively exceeds the higher first level twice, whereby a positive and quick determination of the activated condition of the oxygen sensor can be obtained.
