摘要： An engine body includes a plurality of cylinders, and the intake valve lift-amount of each cylinder is changed based on the engine operating state. A pressure sensor continuously detects the intake pressure, which is the pressure in an intake pipe, to detect the intake pressure decrease amount, which is the amount of decrease in the intake pressure caused due to execution of the intake stroke, of each cylinder. The air quantity variation correction coefficient, which is used to compensate for the variation in the in-cylinder supplied-air quality with each cylinder, is calculated based on the detected intake pressure decrease amount, and the fuel injection amount is corrected using the air quantity variation correction coefficient.

摘要： An intake pressure is successively detected by a pressure sensor, and an intake pressure derivative is calculated. Next, a peak pressure detecting range for each cylinder is set based on the intake pressure derivative. Next, an upward peak pressure and a downward peak pressure of the intake pressure, included in the peak pressure detecting range, are detected for each cylinder. Next, an intake pressure drop for each cylinder is calculated from the upward peak pressure and the downward peak pressure. The in-cylinder charged air amount is calculated based on the intake pressure drop.

摘要： An inter-bank variation detection device of an internal combustion engine provided with a valve opening characteristic setting means (57) for changing the valve opening characteristic of an intake valve (9) for each of the cylinders (#1 to #4) or each of the bank (BL, BR); an indicator detecting means for detecting indicators of the state of combustion for each bank at the time of a first valve opening characteristic set by the valve opening characteristic setting means and the time of a second valve opening characteristic smaller than the first valve opening characteristic; a fuel injection amount variation detecting means (27) for detecting variation of the fuel injection amount for each bank by using the indicator (Xfn) detected by the indicator detecting means at the time of the first valve opening characteristic; and a valve opening characteristic variation detecting means (27) for detecting variation of the valve opening characteristic for each bank by using the indicator (Xsn) detected by the indicator detecting means at the time of the second valve opening characteristic and the variation of the fuel injection amount detected by the fuel injection amount variation detecting means is provided. It is also possible to change the valve opening characteristic of the intake valve by the valve opening characteristic setting means so that the variation of valve opening characteristic for each cylinder or each bank is eliminated.
