摘要： A system for controlling an air/fuel ratio of a four-cylinder internal combustion engine. In the system, an actual air/fuel ratio, at least at upstream or downstream of a catalytic converter installed at an exhaust system of the engine, is intentionally oscillated at least either in its amplitude or cycle. A characteristic of a desired air/fuel ratio as a periodic function is established with respect to time such that the desired air/fuel ratio varies at least either at a predetermined amplitude or cycle within a predetermined period. The characteristic is sampled by a time interval determined on the basis of a time interval between TDC crank angle positions of the engine. Each cylinder's desired air/fuel ratio is then determined from the sampled data, and a fuel injection amount for each cylinder is determined from the respective cylinder's desired air/fuel ratios. Fuel is then supplied to each cylinder in response to the determined fuel injection amount. The actual air/fuel ratio at each cylinder is detected or estimated and feedback controlled to the desired air/fuel ratio.

摘要： There is provided a control system for an internal combustion engine, which is capable of matching an output torque of the engine with a demanded torque excellently when the combustion mode is switched, thereby enhancing drivability. A demanded fuel amount and a demanded torque of the engine are calculated according to detected operating conditions of the engine. A combustion mode is determined to be either the stratified combustion mode or the homogeneous combustion mode according to the demanded torque. A pre-switching demanded fuel injection time period and a pre-switching demanded torque are stored. When the combustion mode is switched, a switching-time demanded fuel amount (limit value) is calculated according to the stored pre-switching demanded fuel injection time period and pre-switching demanded torque, the current demanded torque, and an estimated combustion efficiency parameter.

摘要： Control system for an internal combustion engine, for setting a desired torque in response to operating conditions of the engine and controlling torque based on the set desired torque. A crank angle position sensor detects an engine rotational speed. An accelerator position sensor detects an accelerator position. A required torque is calculated based on results of detection by the crank angle position sensor and the accelerator position sensor. Further, the calculated required torque is smoothed. Then, the present value of the required torque calculated at the present time and the smoothed required torque are compared with each other. When it is determined that the engine is being accelerated, an acceleration assist amount is calculated based on a difference value between the present value of the required torque and the smoothed required torque. Then, the acceleration assist amount is added to the smoothed required torque, whereby the desired torque is set.

摘要： An engine exhaust gas purification system having a catalyst in an exhaust system of the engine, said catalyst reducing nitrogen oxide when exhaust gas generated by the engine is in an oxidizing state. In the system, engine operating parameters, including at least an engine speed and an engine load, are determined and catalyst temperature is determined, and air/fuel ratio is controlled in response to the detected parameters and the determined catalyst temperature, thereby enabling the catalyst to purify NOx in its optimum temperature characteristic range to achieve enhanced NOx constituent purification performance in an oxidizing environment. Alternatively, the air/fuel ratio is controlled in the stoichiometric or richer direction when the catalyst temperature is high, thereby protecting the catalyst from being damaged. The catalyst is a selective-reduction type nitrogen oxide reduction catalyst.

摘要： A system for controlling fuel metering for a multi-cylinder internal combustion engine having a feedback loop which has an adaptive controller and an adaptation mechanism coupled to said adaptive controller for estimating controller parameters .theta.. The adaptive controller calculates a feedback correction coefficient using internal variables that include the controller parameters .theta., to correct a basic quantity of fuel injection to bring a detected air/fuel ratio to a desired air/fuel ratio determined earlier from the detected air/fuel ratio by a dead time d'. The dead time d' is properly determined to be corresponding to a time k at which the air/fuel ratio is detected. Alternatively, the dead time may be determined to be longer than the proper value to eventually improve vehicle drivability, or determined to be shorter than the proper value to compensate for insufficient fuel adhesion correction.

摘要： A system for controlling fuel metering in an internal combustion engine using a fluid dynamic model and the quantity of throttle-past air is determined therefrom. Based on the observation that the difference between the steady-state engine operating condition and the transient engine operating condition can be described as the difference in the effective throttle opening areas, the quantity of fuel injection is determined from the product of the ratio between the area and its first-order lag value and the quantity of fuel injection under the steady-state engine operating condition obtained by mapped data retrieval, and by subtracting the quantity of correction corresponding to the quantity of chamber-filling air. The effective throttle opening area's first order lag is calculated using a weight that varies with the engine speed, so that elongation or shortening of the TDC interval due to the decrease/increase of the engine speed will not affect the determination of the quantity of fuel injection.

摘要： A system for purifying exhaust gas of an internal combustion engine having a catalyst in an exhaust system of the engine, said catalyst reducing nitrogen oxide when exhaust gas generated by the engine is in an oxidizing state. An EGR mechanism is provided for recirculating a part of the exhaust gas to an intake system of the engine, and is controlled such that a ratio of unsaturated and/or aromatic hydrocarbon concentration to nitrogen oxide concentration in the exhaust gas is at or above a predetermined value. The EGR mechanism is further controlled such that oxygen concentration in the exhaust gas is below a prescribed value. An injection timing mechanism is controlled for the same purpose.
