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.

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 the exhaust gas discharged from the engine is initially introduced into the three way catalyst. Secondary air is fed into the exhaust passage between the three way catalyst and the oxidizing catalyst so that the air-fuel ratio of the exhaust gas flowing into the oxidizing catalyst and the NOx absorbent becomes lean.

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.
摘要翻译：发动机包括双桶化油器。安装到排气系统的传感器检测排气中的组分的浓度。控制单元基于来自传感器的信号，将控制信号调度到排气控制阀以改变其阻力。一级和二级路径系统从排气控制阀的出口引出，并分别向正在供应到化油器的主桶中的燃料提供初级排放空气，并将次级排放空气供入到被供应到二级桶中的燃料中的化油器。单向阀安装在次级路径系统中，以便仅使空气流向次级桶，并且不从其流出。因此，当两个桶打开时，排出的空气通过主路径系统被吸入主桶，并且通过次级路径系统通过单向阀将排放空气吸入二次桶中; 但是，当只有主桶打开时，排放空气通过主路径系统被吸入主桶，但没有通过次级路径系统将吸入的空气吸入二次桶，并且单向阀防止反向流动来自次级桶的空气通过次级路径系统，从那里进入主路径系统朝向主桶。
