摘要： In a misfire detection system for an internal combustion engine, a product is calculated at every predetermined crank angle by multiplying a value retrieved from a periodic function defined to model torque generation of individual cylinders synchronously with each combustion cycle, by a detected crank angle velocity, and the product is integrated over a predetermined interval to calculate an integral. The integral is then compared with a predetermined value and is detected whether misfire has occurred in one of the individual cylinders, thereby enabling to detect misfire even when misfire occurs successively in a multiple cylinder engine, identify the misfiring cylinders with good accuracy.

摘要： A control apparatus for controlling an object that is modeled using at least one model parameter is provided. The control apparatus comprises an identifier, a controller and a modulator. The identifier identifies the model parameter. The controller is coupled to the identifier and uses the model parameter to determine a reference input so that an output of the object converges to a desired value. The modulator is coupled to the controller and applies any one of a delta-sigma modulation algorithm, a sigma-delta modulation algorithm and a delta modulation algorithm to the reference input to determine an input into the object. The model parameter is identified based on the output of the object and the reference input. Since the identifier determines the model parameter based on the reference input, the model parameters is prevented from vibrating.

摘要： An adsorbent state determining apparatus is provided for accurately determining the state of an adsorbent including a deterioration as well as for allowing for recovery of the adsorbent if its adsorbent performance can be restored. The adsorbent state determining apparatus determines the state of an adsorbent for adsorbing hydrocarbons contained in exhaust gases. An upstream and a downstream temperature sensor are provided at upstream and downstream locations of the adsorbent in an exhaust system for detecting temperatures of exhaust gases upstream and downstream of the adsorbent. An engine water temperature sensor detects an operating state of the engine. An ECU estimates the temperature of the exhaust gas which should be detected downstream of the adsorbent during adsorption of the adsorbent based on the upstream temperature detected by the upstream temperature sensor and an engine water temperature of the engine detected by the engine water temperature sensor. The ECU then compares the estimated downstream temperature with the detected downstream temperature detected by the downstream temperature sensor during adsorption of the adsorbent to determine the adsorption state of the adsorbent.

摘要： A system for purifying exhaust gas generated by an internal combustion engine having a bypass exhaust gas passage branching from an exhaust pipe which is opened or closed by a switch-over valve, and an adsorbent which adsorbs unburneds component in the exhaust gas installed at the bypass exhaust passage. In the system, when the engine operation is within a high engine speed and high load region, the switch-over valve is operated to open the bypass exhaust gas passage to reduce noise due to switch-over valve chattering, etc. Similarly, the bypass exhaust gas passage is opened at that range, when the exhaust gas temperature is greater or equal to a predetermined value, to introduce high temperature exhaust gas to burn away cloggy material adhered to the adsorbent which would otherwise deteriorate or degrade the adsorbent.

摘要： A control system for an internal combustion engine, which is capable of enhancing the accuracy of fuel control and ignition timing control even when there is a possibility that the reliability of a calculated intake air amount lowers, and enables reduction of manufacturing costs. An ECU of the control system calculates a first estimated intake air amount according to a valve lift, a cam phase, and a compression ratio, calculates a second estimated intake air amount according to the flow rate of air detected by an air flow sensor. The ECU determines a fuel injection amount according to the first estimated intake air amount when an estimated flow rate Gin_vt calculated based on an engine speed, the valve lift, the cam phase, and the compression ratio is within the range of Gin_vt≦Gin1, and according to the second estimated intake air amount when Gin2≦Gin_vt.
