摘要： In an internal combustion engine to which an air pressure actuation mechanism such as a variable vibration isolating support device is installed side by side, the engine speed at the time of idling is made to suitably converge on the target idling speed. The idling speed control device includes: an idling speed control mechanism for controlling the intake air amount of the internal combustion engine to make the engine speed be the desired target idling speed at the time of idling of the internal combustion engine; an air pressure actuation mechanism operated by selectively introducing the atmospheric pressure and the intake tube negative pressure produced in the intake passage on the down stream side of the throttle valve; and an intake air amount compensating mechanism for compensating the adjusting position of the idling speed control mechanism in the direction of decreasing the intake air amount of the internal combustion engine when introducing the intake tube negative pressure after the introduction of the atmospheric pressure into the air pressure actuation mechanism.

摘要： The fault diagnostic apparatus of the present invention detects a failure (a leak) of a fuel tank of an engine. In this invention, space above the fuel level in the fuel tank is connected to a canister. The canister contains an adsorbent to adsorb evaporated fuel in the tank to prevent the evaporated fuel from being released to the atmosphere. Valves are provided to the canister to keep the internal pressure of the canister within a predetermined range. A control circuit of the engine employs a pressure sensor to monitor the internal pressure of the fuel tank, and determines whether the fuel tank has failed in accordance with a change in the internal pressure of the fuel tank. Since the change in the fuel level in the fuel tank varies in accordance with the fuel consumption rate, the change in the pressure in the fuel tank also varies in accordance with the fuel consumption rate. Therefore, the control circuit stops the determining operation when the fuel consumption rate of the engine is too large or too small, to avoid an error in the diagnosis of the fuel tank.
摘要翻译：本发明的故障诊断装置检测发动机的燃料箱的故障（泄漏）。在本发明中，燃料箱中的燃料高度以上的空间与罐连接。容器中含有吸附剂以吸收罐中蒸发的燃料，以防止蒸发的燃料被释放到大气中。将阀提供给罐以将罐的内部压力保持在预定范围内。发动机的控制电路采用压力传感器来监视燃料箱的内部压力，并且根据燃料箱的内部压力的变化来确定燃料箱是否发生故障。由于燃料箱中的燃料液位的变化根据燃料消耗率而变化，所以燃料箱的压力变化也根据燃料消耗率而变化。因此，当发动机的燃料消耗率太大或太小时，控制电路停止确定操作，以避免燃料箱的诊断错误。

摘要： In a diagnostic apparatus for an evaporative fuel purge system having a canister receiving fuel from a fuel tank via a vapor passage, the fuel being supplied to an intake air passage of an internal combustion engine via a purge passage from the canister, a pressure detecting unit detects a pressure in the evaporative fuel purge system. A decision making unit determines whether or not a failure has occurred in the evaporative fuel purge system on the basis of a relationship between the pressure detected by the pressure detecting unit and a decision value. A correction unit corrects the relationship on the basis of a value of a parameter having an influence on the pressure detected by the pressure detecting unit.

摘要： An apparatus for treating fuel vapor from a fuel tank. The apparatus includes a canister for collecting the fuel vapor generated in the fuel tank through a vapor line, a purge line for purging the collected fuel in the canister into an intake passage, and a control valve disposed midway on the purge line. The fuel tank, the canister, the vapor line and the purge line are connectable to one another to define a closed space. A testing device, which is separately provided from the apparatus, tests the sealing of the closed space after the pressure for the testing is introduced into the closed space from the testing device. The apparatus includes an atmospheric valve for connecting the canister with the atmosphere. The atmospheric valve has a diaphragm and a first and a second pressure chambers. The pressure in the canister is introduced into the first pressure chamber. The second pressure chamber has a first pressure port. The purge line has a second pressure port defined between the canister and the control valve. A pipe connects the first pressure port with the second pressure port. The pipe has a single introduction port. The introduction port communicates with the atmosphere when the test is not performed and is connected to the testing device when the test is performed. A check valve is located in the pipe between the introduction port and the second pressure port. The check valve allows the pressure for the testing introduced from the introduction port to be supplied to the second pressure port and prevents the pressure acting on the second pressure port from being released through the introduction port.
