Abstract: A system for detecting malfunctions of an exhaust switch-over valve of an internal combustion engine, which opens/closes a bypass exhaust gas passage branched from an exhaust pipe of the engine and storing an adsorbent that adsorbs unburned components of the exhaust gas generated by the engine when the engine is started. In the system, the entrance temperature and the exit temperature in the bypass exhaust gas passage are detected and compared with each other in a first detection period when the passage is opened and in a second detection period when the passage is closed. Based on this comparison, it is determined whether the valve malfunctions. Alternatively, the valve malfunction is determined by comparing the valve opening/closing state with an instruction to operate the valve. With this, little time lag exists in the detection, thereby improving malfunction detection accuracy.

Abstract: A plant control system controls a plant modeled as a discrete-system model including an element relative to a response delay of the plant and an element relative to a dead time of the plant. The plant control system includes an actuator for generating an input to the plant, a first detector for detecting an output from the plant, and a second detector for detecting the input to the plant.

Abstract: An air-fuel ratio control system for a multi-cylinder engine is provided. An air-fuel ratio sensor is arranged in an exhaust system of the engine for detecting an air-fuel ratio of a mixture supplied to the engine and for generating an output indicative of the air-fuel ratio of the mixture. An adaptive controller determines an amount of fuel to be supplied to the engine with a first predetermined repetition period in a manner such that the output from the air-fuel ratio sensor becomes equal to a desired value. An adaptive parameter-adjusting mechanism adjusts adaptive parameters used by the adaptive controller. In the adaptive parameter-adjusting mechanism, the adaptive parameters are calculated with a second predetermined repetition period longer than the first predetermined repetition period, and output data indicative of results of the calculation is generated. Further, the output data indicative of results of the calculation is smoothed and output data indicative of the smoothed data is generated with a repetition period at least equal to the first predetermined repetition period. The adaptive controller uses the smoothed data as values of the adaptive parameters.

Abstract: An air-fuel control system for use with an internal combustion engine has a catalytic converter in an exhaust system of the engine, for purifying an exhaust gas emitted from the engine, a first exhaust gas sensor in the exhaust system for detecting an air-fuel ratio of the exhaust gas upstream of the catalytic converter, and a second exhaust gas sensor in the exhaust system for detecting the concentration of a component of the exhaust gas which has passed through the catalytic converter, downstream of the catalytic converter. A sliding mode controller determines a correction quantity at a first period to correct the air-fuel ratio of the engine so as to equalize the concentration of the component downstream of the catalytic converter to a predetermined appropriate value, according to a sliding mode control process based on the output from the second exhaust gas sensor. A feedback controller determines a correction quantity at a second period for a rate at which fuel is supplied to the engine so as to converge the concentration of the component downstream of the catalytic converter toward the predetermined appropriate value, based on the correction quantity to correct the air-fuel ratio and the output from the first exhaust gas sensor, and feedback-controls the rate at which fuel is supplied to the engine with the determined correction quantity. The first and second periods are established separately from each other.

Abstract: The objective of the present invention is to provide an exhaust purification system that is capable of purifying exhaust gas during both lean and stoichiometric driving. The exhaust purification system is equipped with: a feedback-use identifier, which identifies parameter values such that the error between the output value from a LAF sensor and the estimated value for the LAF sensor output as obtained from a model equation is minimized; and a stoichiometric driving mode controller. The controller performs feedback control and thereby determines the fuel injection amount such that in the stoichiometric driving mode the equivalence ratio value as calculated from the parameters reaches a target value which is set such that a three-way purification reaction occurs in an under-engine catalyst. The identifier identifies the model parameters before feedback control is initiated by the controller.

Abstract: An exhaust purification system is provided that can continuously maintain a NOx purification rate to be high while suppressing the occurrence of ammonia slip. The exhaust purification system includes a slip determination portion 34 that determines the occurrence of ammonia slip based on an output value NH3CONS of an ammonia sensor 26.

A switching injection amount calculating portion 32 decreases in amount a urea injection amount GUREA by setting a switching injection amount GUREA—SW to a negative value in response to having determined that ammonia slip has occurred, and increases in amount the injection amount GUREA by setting the switching injection amount GUREA—SW to a positive value in response to a storage amount estimated value STUREA having fallen below a predetermined switch storage amount STUREA—SW.

Abstract: An EGR control apparatus for an internal combustion engine, which is capable of accurately controlling an inert gas amount and an inert gas ratio of two types of EGR gas supplied to cylinders of the engine via two paths different from each other, thereby making it possible to ensure a stable combustion state and reduced exhaust emissions. The EGR control apparatus includes a low-pressure EGR device, a high-pressure EGR device, and an ECU. The ECU calculates a target low-pressure opening, calculates an estimated value of an in-cylinder low-pressure inert gas flow rate, which is the estimated value of an inert gas amount included in low-pressure EGR gas supplied to the cylinders via an intake passage, calculates a target high-pressure opening using the estimated value, and controls low-pressure and high-pressure EGR control valves, using the target low-pressure opening and the target high-pressure opening.
