摘要： A fuel metering control system for an internal combustion engine having a plurality of cylinders. The system includes an air/fuel ratio sensor and engine operating condition detecting means for detecting engine operating conditions at least including engine speed and engine load. The basic quantity of fuel injection is determined by retrieving mapped data according to the engine speed and engine load. An adaptive controller is provided to calculate a feedback correction coefficient to correct the quantity of basic fuel injection such that the detected air/fuel ratio is brought to a desired value. The desired air/fuel ratio is corrected by a second air/fuel ratio sensor installed downstream of a catalytic converter.

摘要： An air/fuel ratio feedback control system with the adaptive controller. The adaptive controller has a system parameter estimator which identifies system parameters such that the error between the desired value and the controlled variable outputted from the plant decreases to zero. In the system, a basic fuel injection amount is determined at a feedforward system. The adaptive controller is placed outside of the basic fuel injection amount determining system and receives the desired value (air/fuel ratio) and the controlled value (detected air/fuel ratio) using the system parameters etc. The calculated feedback coefficient is multiplied to the basic fuel injection amount to determine a final injection amount to be supplied to the plant (engine). Variables necessary for the system parameter calculation are limited their change of range so as to make the controller to be realized on a low performance computer with a small word length.

In the estimator, detection response lag time of said air-fuel ratio sensor is approximated as a first-order lag time system to produce state equation from said first-order lag time system. The state equation is discretized for a period delta T to obtain a discretized state equation. A transfer function is calculated from the discretized state equation and is then an inverse transfer function is calculated from said transfer function. And correction coefficient of said inverse transfer function is determined and multiplying with inverse transfer function to the sensor output estimate an air-fuel ratio of an air and fuel mixture supplied to the engine. The correction coefficient is predetermined with respect to engine speed and is made zero at or below a predetermined engine speed.

摘要： A system for controlling fuel metering in an internal combustion engine using a fluid dynamic model and the cylinder air flow past the throttle is determined therefrom. Based on the observation that the difference between a steady-state engine operating condition and a transient engine operating condition can be described as the difference in the effective throttle opening areas, the amount of fuel injection is determined from the product of the ratio between the areas and a basic fuel injection amount under the steady-state engine operating condition obtained by mapped data retrieval and by subtracting a correction amount corresponding to an air flow filling a chamber between the throttle and the cylinder from the product. Under steady-state engine operation, the correction amount becomes zero. In an embodiment, the first-order lag of a detected throttle opening is calculated and based on the value, various parameters including a pseudo manifold pressure are obtained so as to solve sensors' detection timing lag or a pressure sensor's detection lag.

摘要： The present invention provides an intake air control capable of implementing a highly accurate constant negative pressure control with a smaller number of process steps under various environments. The intake air control is applicable to an engine having a variable valve actuation mechanism for adjusting at least a lift amount of an intake valve to control an intake air amount and a throttle valve for keeping a gauge pressure in an intake manifold at a desired gauge pressure. A reference throttle opening area is determined by referring to a first table based on a desired intake air amount. The first table defines a relation between an intake air amount and a throttle opening area under a reference gauge pressure, a reference atmospheric pressure and a reference intake air temperature. A throttle opening area for achieving the desired gauge pressure is determined by correcting the reference throttle opening area with a correction parameter derived based on the Bernoulli's law by using the desired gauge pressure, a current atmospheric pressure and a current intake air temperature.

摘要： In a stoichiometric operation mode after a lean operation mode, a control unit sequentially generates data representing an estimated value of an output VO2/OUT of an O2 sensor after the dead time of an exhaust system, and at the same time generates a target air-fuel ratio KCMD for an exhaust gas upstream of a catalytic converter in order to converge the estimated value to a predetermined target value. The air-fuel ratio of the exhaust gas is controlled at the target air-fuel ratio KCMD. In the stoichiometric operation mode, the reduced state of NOx in the catalytic converter is recognized based on the estimated value of the output of the O2 sensor, and whether the stoichiometric operation mode is to switch to the lean operation mode or not is determined depending on the reduced state of NOx in the catalytic converter.

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.
