摘要： An apparatus for determining leakage in an evaporated fuel processing system is provided. The evaporated fuel processing system extends from a fuel tank to a purge passage through which evaporated fuel from the fuel tank is purged to an intake manifold of an engine. The apparatus comprises a pressure sensor for detecting a pressure of the evaporated fuel processing system, an atmospheric pressure sensor for detecting an atmospheric pressure, and a control unit connected to the pressure sensor and the atmospheric pressure sensor. The control unit detects a stop of the engine. A determination value used for the leakage determination is corrected according to the atmospheric pressure. The evaporated fuel processing system is closed after the stop of the engine is detected. It is determined whether the evaporated fuel processing system has leakage based on the pressure detected by the pressure sensor and the corrected determination value. Since the determination value is corrected according to the atmospheric pressure, leakage is accurately determined regardless of whether the vehicle is located in highlands or lowlands.

摘要： In a malfunction detecting system of an engine cooling apparatus constituted as a radiator having a thermostat that opens/closes a communicating passage between the engine and the radiator, estimated coolant temperature is calculated using a thermal load parameter correlated to rise in the coolant temperature after engine starting, whilst an engine standing time period is detected. Then, the detected engine standing time period is compared with a predetermined value and based on a result of comparison, one of preset threshold values including a malfunction discrimination threshold value and a malfunction discrimination execute threshold value is selected. The selected threshold value is then compared with the estimated coolant temperature or a difference between the estimated coolant temperature and the detected coolant temperature, and it is discriminated that the cooling apparatus has malfunctioned, when the estimated coolant temperature or the difference exceeds the malfunction discrimination threshold value. With this, the malfunction can be detected with high accuracy.

摘要： In a malfunction detecting system of an engine cooling apparatus constituted as a radiator having a thermostat opening/closing an inlet pipe and an outlet pipe, a temperature sensor is installed at the radiator to detect a temperature of the coolant flowing through the radiator. In the system, a period of time since the engine starting is measured and is compared with a predetermined value indicative of a period of time until the thermostat presumably opens. Then, the detected coolant temperature is compared with three reference values, when the measured period of time exceeds the predetermined value and it is discriminated that the cooling apparatus, more specifically, the thermostat of the radiator has malfunctioned, when the coolant temperature exceeds a medium one of the reference values. In addition, it is discriminated the apparatus has malfunctioned, if the coolant temperature exceeds the highest reference value, even when the measured period of time does not exceed the predetermined value. Further, the discrimination is reserved, if the coolant temperature exceeds the lowest reference value, but the coolant temperature does not exceed the highest reference value, while it is discriminated that the apparatus is normal, if the coolant temperature does not exceed the lowest reference value. With this, by directly detecting radiator coolant temperature, the malfunction can be detected with high accuracy.

摘要： An apparatus for determining leakage in an evaporated fuel processing system is provided. The evaporated fuel processing system extends from a fuel tank through a canister to a purge passage through which evaporated fuel from the fuel tank is purged to an intake manifold of an engine. The canister comprises a vent-shut valve that communicates with the atmosphere. The apparatus comprises a pressure sensor for detecting a pressure of the evaporated fuel processing system and a control unit connected to the pressure sensor. The control unit detects a stop of the engine. After the stop of the engine is detected, the control unit closes the vent-shut valve to close the evaporated fuel processing system. The control unit determines whether the evaporated fuel processing system has leakage after the evaporated fuel processing system is closed based on the detected pressure and a predetermined determination value. The control unit prohibits the leakage determination if the detected pressure is not within a predetermined range. Thus, it is prevented that a state occurs where the vent-shut valve does not open due to the pressure of the evaporated fuel processing system when the leakage determination is being performed.
