摘要： An air bypass valve failure detecting device outputs an opening command to an air bypass valve when a throttle valve suddenly closes, thereby prevent surging from occurring in a second intake passage between a turbocharger and a throttle valve. When the opening command is outputted to the air bypass valve, failure detection for the air bypass valve is permitted only if an intake air quantity of an engine immediately before a closing command is changed to the opening command is equal to or larger than a predetermined value. Thus, it is possible to prevent the failure detecting device from erroneously determining that the air bypass valve is normal although valve closing failure of the air bypass valve has occurred. This is because, when the intake air quantity is smaller than the predetermined value, surging does not occur in the second intake passage even if the valve closing failure of the airy bypass valve has occurred.

摘要翻译： 当节气门突然闭合时，空气旁通阀故障检测装置向空气旁通阀输出打开命令，从而防止在涡轮增压器和节流阀之间的第二进气通道中发生喘振。 当打开命令被输出到空气旁通阀时，只有紧接关闭命令之前的发动机的进气量改变为打开命令，才允许空气旁通阀的故障检测等于或大于预定值 。 因此，尽管发生了空气旁通阀的关闭故障，但是可以防止故障检测装置错误地确定空气旁通阀是正常的。 这是因为，当进气量小于预定值时，即使发生通风旁通阀的关闭故障，也不会在第二进气通道中产生喘振。

摘要： A stop control system for an internal combustion engine, which is capable of accurately stopping a piston at a predetermined position during stoppage of the engine while preventing occurrence of untoward noise and vibration. After stopping the engine 3, the stop control system 1 for the engine 3 according to the present invention executes a first stage control (step 34) in which a throttle valve 13a is controlled to a first stage control target opening degree ICMDOFPRE smaller than a second predetermined opening degree ICMDOF2, in order to stop the piston at the predetermined position, before executing a second stage control (step 42) in which the throttle valve 13a is controlled to the second predetermined opening degree ICMDOF2. Further, the stop control system 1 stabilizes initial conditions at the start of the second stage control by setting a first stage control start rotational speed NEICOFPRE and a first stage control target opening degree ICMDOFPRE according to a change in a corrected target stop control start rotational speed NEICOFREFN (steps 71 and 85).

摘要： An evaporative fuel processing system for processing evaporative fuel generated a fuel tank. A canister temporarily stores evaporative fuel generated in the fuel tank. A charge passage connects the fuel tank and the canister. A first purge passage connects the canister and an intake pipe of an internal combustion engine having a turbocharger. A purge control valve is provided in the first purge passage for adjusting a flow rate of gases flowing through the first purge passage. A second purge passage connects a downstream side of the purge control valve of the first purge passage and an upstream side of the turbocharger of the intake pipe. A jet pump is mounted on the second purge passage. A pressurized air supply passage supplies air pressurized by the turbocharger to the jet pump. The jet pump includes a nozzle for discharging the pressurized air supplied through the pressurized air supply passage.
