摘要： A control apparatus for an internal combustion engine is provided which performs intake air flow control for controlling an engine speed to a target engine speed during starting of the engine, by adjusting a throttle opening depending upon the engine speed. The control apparatus judges a degree of deterioration of a combustion state in the engine, based on a difference between a predetermined reference peak engine speed and an actual peak engine speed, and switches from the intake air flow control to ignition timing control for controlling the engine speed when the engine operates in a poor combustion state, at a point of time that is determined based on the degree of deterioration of the combustion state.

摘要： An exhaust gas purification device comprising a three way catalyst, an oxidizing catalyst and a NOx absorbent which are arranged in this order in the exhaust passage. A rich air-fuel mixture is burned in the combustion chamber, and secondary air is supplied upstream of the three way catalyst so as to make the air-fuel ratio of the exhaust gas flowing into the three way catalyst a rich air-fuel ratio greater than the air-fuel ratio of the air-fuel mixture burned in the combustion chamber. Further, secondary air is supplied upstream of the oxidizing catalyst to make the air-fuel ratio of the exhaust gas flowing into the oxidizing catalyst and the NOx absorbent slightly leaner than the stoichiometric air-fuel ratio.

摘要： A boost pressure control system for a vehicle engine equipped with a supercharger and a torque converter having a lock-up clutch, in which the boost pressure is controlled by adjusting the degree of the opening of an air bypass valve and the ON/OFF position of the supercharger in such manner that the different control characteristics of the boost pressure are selected in accordance with whether the lock-up clutch of the torque converter is turned ON or OFF, i.e., when the lock-up clutch is turned ON, the supercharger is started at a lower engine load, and the degree of the opening of the air bypass valve is set smaller, thereby enabling the lock-up operation of the torque converter under running conditions in which a higher driving torque is required and, thereby widening the operating range of the lock-up operation of the torque converter and improving the fuel economy of the vehicle.

摘要： An engine includes a double barreled carburetor. A sensor mounted to the exhaust system detects the concentration of a component in the exhaust. A control unit, based on a signal from the sensor, dispatches a control signal to an air bleed control valve to vary its resistance. Primary and secondary path systems lead from the outlet of the air bleed control valve and respectively supply primary bleed air into the fuel which is being supplied into the primary barrel of the carburetor and secondary bleed air into the fuel which is being supplied into the secondary barrel of the carburetor. A one way valve is fitted in the secondary path system so as to allow air flow only towards the secondary barrel, and not away therefrom. Thus, when both barrels are opened, bleed air is sucked in to the primary barrel through the primary path system, and also bleed air is sucked in to the secondary barrel through the secondary path system past the one way valve; but, when only the primary barrel is opened, bleed air is sucked in to the primary barrel through the primary path system, but no bleed air is sucked in to the secondary barrel through the secondary path system, and the one way valve prevents reverse flow of air from the secondary barrel through the secondary path system and thencefrom into the primary path system towards the primary barrel.

摘要： A boost pressure control system for an engine, by which the degree of opening of the air bypass valve is adjusted and on/off of a mechanical supercharger operation is controlled to obtain an appropriate boost pressure. In the system, the degree of opening of the air bypass valve is adjusted in accordance with the load of the engine, based on different characteristics selected in accordance with whether the operation of the supercharger is started or stopped. If the engine is operated in a non-boost region, when the supercharger is operating the degree of opening of the air bypass valve is made larger to reduce the compression work of the supercharger, and when the operation of the supercharger is stopped, the degree of opening of the air bypass valve is made smaller to ensure that the air flow through the supercharger maintains the rotation of the rotors of the supercharger.
