摘要： PURPOSE:To maintain a stable condition of idling even when a load applied to an internal combustion engine has rapidly changed, by providing a control valve opening timing determination means and the like and thereby ensuring a specified valve opening time length for each cylinder in consideration of the number of engine revolutions and the load applied to the engine. CONSTITUTION:The apparatus has a control valve opening timing determination means I. In this means I, when the valve opening time length calculated by a control valve opening time length calculator G is smaller than a specified valve opening time length determined from the number of revolutions of an internal combustion engine, a valve opening timing for a control valve C is determined from a valve opening time length calculated on the basis of a control valve closing timing set beforehand and fixed at a time prior to an intake valve opening timing. On the other hand, when the former is larger than the latter, the valve opening timing for the control valve C is determined from said latter, i.e., the number of engine revolutions. And a specified valve opening time length is ensured for each cylinder in consideration of the number of engine revolutions and the load applied to the engine. This can maintain a stable condition of idling even when the load has rapidly changed.

摘要： PURPOSE:To eliminate scattering in torques generated on respective cylinders by correcting an opening time of a control valve by each cylinder in such a manner as to make the pressure of the intake valve constant, thereby making the flow rate of an intake air of each cylinder constant. CONSTITUTION:A control valve 55 operates to control a bypass intake passage for communicating the upper and lower portions of a cut-off valve of each cylinder to each other. The opening time of the control valve 55 is set by valve opening time setting means 54 according to the engine operating state. In such an air supply, the pressure on the upstream side of the cut-off valve is detected by intake pipe pressure detecting means 51. The average value of the detected intake pipe pressures is calculated by average pressure arithmetic means 52. Furthermore, at least before the engine idling, the correcting means 53 operates to correct, by each control valve, the above opening time according to the difference between the above average pressure and each intake pipe pressure.

摘要： PURPOSE:To discriminate a specific cylinder in defective operation automatically and immediately by judging the operation of a control valve to this specific cylinder to be defective at the time of the difference value between the rotating speed of the specific cylinder at its explosion stroke and the average rotating speed of all the cylinders exceeding the specified value. CONSTITUTION:In the idling state, a cutoff valve 4 closes the intermediate part of a main intake passage 2 in such a way as to leave the sufficient volume to hold the specified air quantity necessary for an intake port 7 to maintain idling. A control valve 5 switches an auxiliary intake passage 3 by-passing the cutoff valve 4. Hereupon, an ECU 13 detects the rotating speed of a crankshaft every explosion stroke of each cylinder 1, determines each detected rotating speed as the rotating speed of the specific cylinder 1 at its explosion stroke at that time and compares each rotating speed with the average rotating speed of all the cylinders. When the difference value between both rotating speed exceeds the specified value, the ECU judges the operation of the control valve 5 to the specific cylinder to be defective. The specific cylinder 1, to which the defective operation of the control valve 5 is generated, can be thereby discriminated automatically and immediately.

摘要： PURPOSE:To permit the control to each different air-fuel ratio for each group by installing a correcting means for obtaining the fuel injection quantity by feedback-correcting the fundamental fuel injection quantity on the basis of the detection signal of an air-fuel ratio sensor. CONSTITUTION:In a correcting means, the fuel injection quantity is obtained by feedback-correcting the fundamental injection quantity on the basis of the detection signal of an air-fuel sensor. In one injection means, injection is carried- out by one group of fuel injection valves 12g. In a lean-state generating means, the fuel injection quantity to the combustion chambers of the other group of cylinders 12b and 12c is set to a precribed rate of the obtained fuel injection quantity. Thus, the air-fuel ratio can be controlled to a different value for each group with the simple constitution.

CONSTITUTION: In a drive in which a fuel injection valve 12 is installed in an intake air branch 11 communicated with an intake air port 5 of each cylinder for 4-cylinder engine, ignition is set in the order of #1, #3, #4, and #2, the #1 and #4 cylinders are set as a lean cylinder which provides a lean air-fuel ratio, and the #3 and #2 cylinders as a stoiki cylinder which provides a value near to a theorectical air-fuel ratio. In this internal-combustion engine, control is effected such that fuel is injected through a fuel injection valve 12 on the lean cylinder side between the second stage of an exhaust stroke and a suction stroke, and the fuel is injected through the fuel injection valve 12 on the stoiki cylinder side during a compression stork and the first stage of the exhaust stroke. This increases a learn combustion limit, and decrease production of NOx.
