摘要： An air-fuel ratio estimator for estimating air-fuel ratio of an air and fuel mixture supplied to an internal combustion engine from an output of an air-fuel ratio sensor. 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 fuel metering control system for an internal combustion engine, having a feedback loop. In the system, the quantity of fuel injection (Tim) to be supplied to the engine (plant) is determined outside of the feedback loop. A first feedback correction coefficient (KSTR) is calculated using an adaptive law, while a second feedback correction coefficient (KLAF(KSTRL)), whose control response is inferior to the first feedback correction coefficient is calculated using a PID control law. The feedback correction coefficients are calculated such that the plant output (air/fuel ratio) is brought to a desired value (desired air/fuel ratio). The engine is equipped with a variable valve timing mechanism which switches the valve timing between characteristics for low engine speed and those for high engine speed. If the characteristic for high engine speed is selected, the second feedback correction coefficient is used for fuel injection quantity correction.

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： An air-fuel ratio control system for an internal combustion engine controls the air-fuel ratio of a mixture supplied to the engine to a desired air-fuel ratio in response to an output from an exhaust gas ingredient concentration sensor. A first value of the desired air-fuel ratio is calculated based on the rotational speed of the engine and the load on the engine. A second value of the desired air-fuel ratio is calculated based results of determination on whether a vehicle on which the engine is installed has just started from a standing position thereof. A third value of the desired air-fuel ratio is calculated based on results of determination on whether the temperature of the engine is lower than a predetermined value. The largest value of at least the first to third values of the desired air-fuel ratio is set to a final value of the desired air-fuel ratio.

摘要： An air-fuel ratio control system for an internal combustion engine having at least one intake valve with its valve timing changeable at least between low-speed valve timing suitable for engine operation in a low engine rotational speed region, and high-speed valve timing suitable for engine operation in a high engine rotational speed region. When changeover is to be effected from the low-speed valve timing to the high-speed valve timing, an ECU changes the desired air-fuel ratio to be applied when the low-speed valve timing is selected, to one to be applied when the high-speed valve timing is selected, and changes the valve timing to the high-speed valve timing after the desired air-fuel ratio has been changed to the one to be applied when the high-speed valve timing is selected.

摘要： A system for purifying exhaust gas generated by an internal combustion engine including a bypass branching out from the exhaust pipe downstream of a catalyst and merging to the exhaust pipe, an adsorber installed in the bypass, a bypass valve member which closes the bypass, and an EGR conduit connected to the bypass at one end and connected to the air intake system for recirculating the exhaust gas to the air intake system. The bypass valve member is opened for a period after engine startup to introduce the exhaust gas such that the adsorber installed in the bypass adsorbs the unburnt HC component in the exhaust gas. The adsorber adsorbs the HC component when the exhaust temperature rises and the adsorbed component is recirculated to the air intake system through the EGR conduit. In the system, the bypass valve is provided at or close to the branching point in the exhaust pipe and a chamber is provided close to the branching point such that the conduit is connected to the bypass at the one end in the chamber. The bypass valve member is combined with an exhaust pipe valve member as a combination valve such that when the bypass valve member closes the bypass, the exhaust pipe valve member opens the exhaust pipe. With the arrangement, the system can effectively prevent the exhaust pipe from being clogged even when a valve for closing a bypass is stuck in the closed position. At the same time, the system can provide a relatively short EGR conduit for recirculating unburnt HC component adsorbed from the adsorber and the adsorption and desorption are conducted optimally.

The adsorber adsorbs the HC component in the exhaust gas when the exhaust gas temperature rises and the adsorbed component is recirculated to the air intake system through the EGR conduit.
