摘要： An engine controller performs low opening degree control during a first intake stroke period since an engine start is commenced until first intake strokes of respective cylinders end. Thus, an opening degree of an intake throttle valve is controlled to a fully closed position or proximity of the fully closed position such that intake pressure downstream of the intake throttle valve becomes equal to or lower than critical pressure with respect to intake pressure upstream of the intake throttle valve during an intake stroke of each cylinder. The controller calculates a leak air quantity at the time when the intake throttle valve is fully closed based on an intake air quantity sensed during the low opening degree control. The controller corrects a feedback gain of idle speed control in accordance with the leak air quantity of the intake throttle valve.

摘要： A secondary air pipe is connected on the upstream side from catalyst in an exhaust pipe, and a secondary air pump is provided at an upstream portion of the secondary air pipe. An opening/closing valve for opening/closing the secondary air pipe is provided on the downstream side from the secondary air pump. A pressure sensor for detecting pressure within pipe is provided between the secondary air pump and the opening/closing valve. An ECU calculates a secondary airflow rate based upon difference pressure between both secondary air supply pressure which is detected by the pressure sensor when the opening/closing valve is opened under such a condition that the secondary air pump is operated, and also, shutoff pressure which is detected by the pressure sensor when the opening/closing valve is closed.

摘要： The present invention is directed to provide a controller for an internal combustion engine, capable of suppressing deterioration in drivability of an engine. A controller for an internal combustion engine has lean control means for calculating a torque margin from a reference engine speed and an actual engine speed and setting a combustion air-fuel ratio of an internal combustion engine to the lean side on the basis of the torque margin. In addition to correction of a fuel injection amount by the lean control means, the fuel injection amount is further corrected on the basis of a final correction value for reducing deterioration in drivability. The final correction value is set by selecting either a correction value which is set on the basis of an engine speed fluctuation amount or a final correction value of last time, which suppresses deterioration in drivability more. Thus, the operation of setting the air-fuel ratio to the lean side while considering deterioration in drivability can be performed.

摘要： A fuel injection control device for an engine executes a split injection constructed by a fixed injection and a variable injection. A required injection amount of the fixed injection is set in a low range. A required injection amount of the variable injection is set in a high range. An injection amount in the high range is larger than that of the low range. The required injection amount of the variable injection is changed within the high range while the required injection amount of the fixed injection is fixed when a load of the engine is varied while the split injection is performed. An injection control characteristic is corrected based on an actual air-fuel ratio detected before the load is varied and an actual air-fuel ratio detected after the load is varied.
