摘要： Exhaust gas cleaner system for an automotive internal combustion engine includes an air introduction pipe 8 for introducing secondary air, heated initially by a heater 23, to the catalytic converter unit 7 mounted on the exhaust pipe 3. The ignition timings of the engine is retarded at least during the time when the secondary air is heated by the heater 23. Preferably, the number of ignition timings are counted by a counter modulo 5, for example, in the case of a four-cylinder engine, and the ignition timings are retarded when the counter content is 3 or 4, such that the ignition timings of the cylinders are retarded intermittently. Alternatively, the retardation of the ignition timings may be terminated before the introduction of the heated secondary air is terminated.Where two first and second catalytic converter units 7a and 7b are provided, secondary air distributed by a change-over valve 10a is heated separately by heaters 23b and 23c.To reduce the burden imposed on the engine, the generation of power by the AC generator 28 may be suspended when either the flow control valve 10b or the heater 23 is operated.

摘要： By controlling a high pressure pump with the use of a cam angle signal so as to open it and then close it after the lapse of a prescribed period corresponding to an amount of discharge, a fuel supply control apparatus for an internal combustion engine is capable of achieving the simplification of control while ensuring controllability without requiring correction even if valve timing is changed. A crank angle sensor generates a crank angle signal SGT in synchronization with the rotation of a crankshaft so as to supply the fuel in a fuel tank to an injector installed in a combustion chamber of each engine cylinder. A cam angle sensor generates the cam angle signal SGC in synchronization with the rotation of a camshaft. A high pressure pump has a suction stroke and a discharge stroke synchronized with the rotation of the camshaft and supplies the fuel to the injector. An ECU changes an effective stroke related to an exhaust stroke of the pump based on the cam angle signal SGC.

摘要： A valve timing control apparatus for an engine. Presence/absence of a torque demand (xtq) is estimated upon starting of a lock pin release control to thereby alter a change rate (&bgr;) of a target phase angle in dependence on presence/absence of the torque demand (xtq). Unless torque demand is issued, the change rate is set to a small value (&bgr;2) for suppressing the change of the target phase angle (&thgr;t) after detection of release of the lock pin in order to avoid a shock unexpected by a driver. When the torque demand is issued, the change rate is set to a large value (&bgr;1) for allowing the target phase angle to approach speedily to a base target phase angle (&thgr;map) for thereby minimizing a delay in response involved in the phase angle detection through the lock pin release control.

摘要： Disclosed is a fuel supply device for an internal combustion engine, which is capable of preventing fuel pressure control problems caused by divergence of a feedback control amount in pump control. A target fuel pressure is computed, and a pump discharge quantity is computed as a feed forward quantity in accordance with an amount of change in the target fuel pressure. A determination is made as to whether or not the feed forward quantity is zero, and when the feed forward quantity is zero, a feedback correction quantity is computed based on the target fuel pressure and the actual fuel pressure, and feedback control is performed. In the case where the feed forward quantity is not zero, the computation of the feedback correction quantity is stopped and the feed forward control is continued.

摘要： A valve timing control apparatus for an internal combustion engine is capable of ensuring good response within a control range, stability outside the control range, and durability without increasing the capacity of electric power for a drive circuit and an OCV coil. The valve timing control apparatus includes an intake vale 31, an exhaust valve 32, an engine operating condition detecting section (3, 11, 14), a target valve timing calculating section 21, variable valve timing mechanisms 15, 16, an actual valve timing detecting section (14, 17, 18), a control amount calculating section 21 for calculating a control amount based on target valve timing, actual valve timing and engine operating conditions, and an actual valve timing control section (19, 20) for outputting the control amount as an output control amount to the variable valve timing mechanisms. When the target valve timing is outside a prescribed control range, the control amount calculated by the control amount calculating section 21 is not made as an output control amount supplied to the actual valve timing control section (19, 20).

摘要： There is disclosed a valve timing controller having excellent response and used with an internal combustion engine. The controller performs a corrective control operation according to the oil pressure control characteristics of the actually mounted valve. The valve timing controller comprises an intake cam, an exhaust cam, an actuator for varying the phase of rotation of one of the cams relative to the crankshaft of the engine, an oil pressure control valve for applying oil pressure on the actuator, and a control means for controlling the valve timing by controlling the oil pressure output from the oil pressure control valve. The oil pressure output is controlled by controlling the current through the solenoid in the oil pressure control valve. The two cams are driven by the crankshaft of the engine. The intake cam opens and closes the intake valve. The exhaust cam opens and closes the exhaust valve. The control means detects the currents supplied into the solenoid to activate the actuator in different operating conditions of the engine. The characteristics of the oil pressure control valve are detected from the difference in the current value under these different operating conditions. An amount of control current is determined.
