摘要： A system for detecting air-fuel ratio of an internal combustion engine by sampling outputs of an air-fuel ratio sensor installed at an exhaust system confluence point of said engine. A timing map is prepared to be retrieved by the engine speed and manifold absolute pressure to determine one among sampled data which are successively stored in buffers. It is selected such that as the engine speed decreases or the manifold absolute pressure increases, a datum sampled at earlier crank angular position is selected. At an engine equipped with a variable valve timing mechanism, a datum sampled at earlier crank angular position is selected in the valve timing is controlled for high engine speed provided that the engine speed and manifold absolute pressure is constant. The sampled data stored in the buffers may be transferred to another buffers at a predetermined crank angular position. The sampled data is corrected by an environmental conditions including atmospheric pressure, a mixture or sensor degradation. Each buffer may have a plurality of sampled data.

摘要： A method for detecting and controlling the air-fuel ratio of a multicylinder internal combustion engine through an output of a single air-fuel ratio sensor installed at a confluence point of the exhaust system of the engine. The detection response delay is assumed to be a first-order lag and a state variable model is established. Further, the air-fuel ratio at the confluence point is assumed to be a sum of the products of the past firing histories of the each cylinder of the engine and a second state variable model is established. An observer is then designed to observe the internal state of the second model and the air-fuel ratio at the individual cylinders are estimated from the output of the observer. The deadbeat control is carried out by calculating a ratio between the estimated air-fuel ratio and a target air-fuel ratio. The calculated ratio is multiplied to a correction value at a preceding control cycle earlier by a number corresponding to the number of the engine cylinders.

摘要： A control system is provided in an internal combustion engine in which a valve timing such as an opening time point and lift amount of an intake valve can be switched to a low-speed or high-speed valve timing within a lean-burn control range established in accordance with the operational state, such as an intake pipe internal absolute pressure and an engine revolution number of the engine, wherein an air-fuel ratio of an air-fuel mixture supplied to the internal combustion engine is enriched for a predetermined time when the valve timing is switched from the low-speed valve timing to the high-speed valve timing while carrying out a lean-burn control. Thus, even when the valve timing is switched over to the high-speed valve timing, the lean-burn control is carried out to prevent a misfiring or an unstable combustion state caused when the valve timing is switched during the lean-burn control, thereby providing a reduction in emission and an enhancement in drivability, while enhancing the specific fuel consumption.

摘要： A fuel injection type internal combustion engine has a pair of intake ports provided in a cylinder head to connect a pair of intake valve bores facing a combustion chamber with a single intake inlet end. A fuel injection valve is disposed in an orientation frm the intake inlet end toward both the intake valve bores and includes an assist-air supply means for finely atomizing the fuel. A valve operating mechanism is provided for selectively stopping the intake through one of the intake ports in accordance with the operational condition of the engine. A control means is connected to the assist-air supply means for controlling the assist-air supply means to stop the supply of assist air from the assist-air supply means in at least a portion of an operational region in which the intake through one of the intake ports is substantially stopped. This ensures that the impediment of the production of the swirl by the assist air can be avoided by stopping the supply of assist air in a condition in which the intake through one of the intake ports is substantially stopped to produce a swirl in the combustion chamber.

摘要： An air-fuel ratio control system for an internal combustion engine having a fuel injection valve for each cylinder and an electronic air control valve (EACV) for controlling intake air bypassing the engine throttle valve. When the target air-fuel ratio is switched over from a rich value to a lean value, the amounts of fuel injected into the cylinders, for example, #1, #2, #3 and #4 cylinders are controlled so that they are sequentially decreased at predetermined intervals, and the EACV is controlled to be opened stepwise. This causes a decrease in engine torque generated by the switching-over of the target air-fuel ratio to be offset by an increase in engine torque generated by an increase in amount of air drawn, thereby preventing the generation of a torque shock. At this time, the target opening degree of the EACV is corrected based on the magnitude of the interval and the magnitude of a loading of the internal combustion engine, thereby further effectively preventing the generation of the torque shock.

摘要： A system for controlling motive force of a vehicle having an engine and a continuously variable automatic transmission connected to the engine to transmit engine torque to a drive shaft of the vehicle. In the system, a desired motive force is calculated or determined from the detected accelerator (pedal) position and vehicle speed, and based on the determined motive force a desired engine speed, more specifically a drive shaft speed of the transmission, is calculated or determined. Then inertia torque acting on the vehicle is calculated or determined based on at least the determined speed and detected speed, and a desired throttle opening is corrected by the determined inertia torque when the vehicle accelerates or decelerates. With the arrangement, the vehicle response delay due to the inertia torque is adjusted and hence, drivability and fuel economy performance are enhanced.
