摘要： In an emission control apparatus of an internal combustion engine in which an emission control catalyst is disposed in an engine exhaust passage, if fuel cut is performed during a decelerating operation of the engine when the temperature of the emission control catalyst is to be quickly reduced by a secondary air supply device supplying fresh air to the emission control catalyst during the decelerating operation of the engine, the supply of fresh air from the secondary air supply device to the emission control catalyst is started after a fuel cut executing condition is met but before the fuel cut is actually executed. Therefore, the temperature of the catalyst is reduced before the exhaust air-fuel ratio shifts to the lean side due to execution of the fuel cut. Thus, exposure of the catalyst to a deteriorating condition of high temperature and lean air-fuel ratio is prevented.
摘要翻译：在排气控制催化剂配置在发动机排气通路中的内燃机的排放控制装置中，在排气控制催化剂的温度要快速降低时，如果在发动机的减速运转时进行燃料切断，二次空气供给装置，在发动机的减速运转中向排放控制催化剂供给新鲜空气的情况下，在燃料切断执行条件满足后，在二次空气供给装置向排放控制催化剂供给新鲜空气之前，实际执行燃油切割。因此，由于执行燃料切断，在排气空燃比变为稀薄侧之前，催化剂的温度降低。因此，可以防止催化剂暴露于高温稀薄空燃比的劣化状态。

摘要： A charging control apparatus including means for shortening a running-up period of the second turbocharger with an exhaust bypass valve when an instant engine speed is low, so that torque shock during the transition from one-turbocharger-operation to two-turbocharger-operation is decreased. During rapid acceleration at high engine speeds, an exhaust switching valve is opened at once. Further, the reference engine speed and the reference intake air quantity for switching to two-turbocharger-operation are varied in accordance with the gear shift position, so that an optimum switching to two-turbocharger-operation is obtained.

摘要： An internal combustion engine with a dual turbocharger system includes an air bypass conduit connecting a downstream portion of a first turbocharger compressor with an upstream portion of a second turbocharger compressor so that the length of the air bypass conduit is relatively long. When a throttle is rapidly closed, an air bypass valve installed in the air bypass conduit is opened and the compressed air downstream of the throttle valve is returned to the upstream of the turbocharger compressor to suppress occurrence of a surging at the turbocharger compressor. Since the air bypass conduit is relatively long, the compressed and circulated air is effectively cooled when flowing through the air bypass conduit and melting of an impeller of the turbocharger compressor is prevented.

摘要： The exhaust gas purifying catalysts sometimes generate H2S which emits exhaust odor under reducing atmosphere. However, in the ordinary air-fuel ratio control, it takes much time to establish sufficient oxygen atmosphere for suppressing H2S emission when the maximum oxygen storage amount which the exhaust gas purifying catalyst can store is large. Thus, the fuel cut control apparatus of an internal combustion engine executes fuel cut to bring oxygen in the exhaust gas into an excessive state when the maximum oxygen storage amount is a predetermined amount or more. As a result, sufficient oxygen can be stored in the exhaust gas purifying catalyst. Even when the maximum oxygen storage amount of the exhaust gas purifying catalyst is smaller than the predetermined amount, if the temperature of the exhaust gas purifying catalyst is lower than predetermined temperature, fuel cut is executed. In this case, influence which is given to deterioration of the catalysts is small even if the fuel cut is executed and the inside of the catalysts is under the oxygen atmosphere. On the other hand, if the temperature of the exhaust gas purifying catalyst is the predetermined temperature or higher, the fuel cut is not executed. Since the deterioration of the catalyst is promoted when the catalyst is under the oxygen atmosphere at high temperature, priority is given to prevention of deterioration of the exhaust gas purifying catalyst.

摘要： A vehicular engine speed controller for keeping the engine speed constant while preventing the overrunning of the engine. The vehicle includes a propeller shaft connected to driving wheels and a torsional damper for connecting the propeller shaft with the engine drive shaft. The controller comprises a detector for detecting a value corresponding to engine speed, and an injection control device for controlling injectors, based on the detected value from the detector. The control device stores a first and second determining values (Da and Db). The control device halts fuel supply from the injector when the detected value exceeds the first value (Da), and resumes fuel supply when the detected value becomes below the second value (Db). The control device further causes the injector to execute the resumption and halt of fuel injection at least one time, when the detected value is changed to a smaller value than the first value (Da) from a larger value than the first value (Da), thereby extinguishing the torsional energy accumulated in the torsional member. The engine speed is not affected by the torsional damper.

摘要： An EGR apparatus includes an EGR conduit, an EGR valve, a first passage connecting a portion of an intake conduit downstream of a throttle valve and the EGR valve, and a second passage connecting a portion of the intake conduit upstream of the throttle valve and a medium portion of the first passage. A two-way solenoid valve is installed in the first passage between the intake conduit and a connecting portion where the first passage and the second passage join. Further, a fixed throttle is disposed in the second passage. By removing a VCV of a conventional EGR apparatus from the EGR apparatus and by replacing a three-way VSV of the conventional apparatus with a combination of the two-way solenoid valve and the fixed throttle, a problem of non-cutting of EGR, which can occur in the conventional apparatus, does not occur in the EGR apparatus of the invention.

摘要： An evaporated fuel discharge suppressing apparatus includes a main purge conduit and a bypass purge conduit. The main purge conduit connects a canister and an intake conduit of an engine downstream of a throttle valve, and a purge control solenoid valve is installed in the main purge conduit. The bypass purge conduit bypasses the purge control solenoid valve. Even if the purge control solenoid valve sticks in a closed position, evaporated fuel adsorbed by the canister can flow into the intake conduit of the engine through the bypass purge conduit so that the evaporated fuel in the canister is not discharged into the atmosphere.
