A control system for an internal combustion engine having a fuel injector located in a combustion chamber of the engine for injecting fuel into the combustion chamber. The fuel injection timing stored in a fuel injection timing map is retrieved according to the detected engine operating condition to determine the fuel injection timing. An actual ignition timing of the fuel injected into the combustion chamber is detected. An ignition delay of the actual ignition timing with respect to the target ignition timing, which is set according to the engine operating condition and a fuel injection timing correction amount, is calculated according to the calculated ignition delay. The fuel injection timing is corrected with the fuel injection timing correction amount, and the fuel injection is executed according to the corrected fuel injection timing.

A pulse signal generator using a magnetic device that can cause a large Barkhausen effect, comprises means having a number of pits and projections and generates pulses according to the behavior of these, the means being capable of moving the pits and projections in a first or second direction, the pits and projections being disposed in the moving direction with some of the projections missing or some of the pits filled. The value of the ratio between the time interval of pulses generated by portions other than a projection-missing portion and the time interval of pulses generated by the projection-missing portion or the value of the ratio between the time interval of pulses generated by portions other than a pit-filled portion and the time interval of pulses generated by the pit-filled portion differs between when the pits and projections move in the first or second direction.

The invention provides an exhaust gas purification device that can prevent deterioration of the emission during a regeneration process for a particular filter for trapping particulates contained in the exhaust gas. Particulate filter regeneration timing determining unit estimates the amount of particulates trapped by the particulate filter to determine the filter regeneration timing based on the estimated particular amount. In response to the regeneration timing determination, heating unit heats the particulate filter to raise an exhaust gas temperature, so that a particulate filter regeneration process starts. At this time, intake air amount reducing unit reduces the intake air amount to raise the exhaust gas temperature while combustion maintaining unit controls the combustion in the internal-combustion engine so as to be maintained in a desired condition.

Hybrid vehicle

An input drive power applied to an automatic transmission is sequentially recognized. When there is a demand for the automatic transmission to make a gear shift, a clutch mechanism is disengaged, and a drive power generated by an electric motor connected to the automatic transmission at an output side of the clutch mechanism is controlled depending on the input drive power (input drive power immediately prior to a gear shift) that is applied to the automatic transmission immediately before the clutch mechanism starts to be disengaged. The drive power generated by the electric motor is controlled such that a drive power equivalent to the input drive power immediately prior to a gear shift is applied from the electric motor to the automatic transmission.

A two-cycle action cam having two protruding parts,and,and a four-cycle action cam,having one protruding part,are selectively used by a cam change mechanism,. The two-cycle action cam,effects opening of the inlet and exhaust valves once per revolution of the crankshaft and the four-cycle action cam,effects opening of the inlet and exhaust valves once per two revolutions of the crankshaft. The four-cycle action is selected when the engine is in the low revolving speed and running at a low load and the two-cycle action is otherwise selected.

Heating device for an exhaust gas purification catalytic converter

An actuator is connected to one of components forming a power transmitting device capable of transmitting a power provided by a valve operating cam provided on a cam shaft, so that the actuator can drive an engine valve in a lift amount which is obtained by addition of a lift amount of the engine valve based on a cam profile of the valve operating cam and a lift amount of the engine valve based on the operation of the actuator. Thus, a portion of the lift amount of the engine valve is borne by the valve operating cam, whereby a valve-opening power borne by the actuator can be reduced, as compared with a system designed so that the engine valve is driven by only the actuator only. The amount of electric power consumed by the actuator can be smaller.
