The apparatus comprises a cooling circuit including serially-connected cooling systems for cooling electric devices by circulating a refrigerant; a circulating pump for circulating the refrigerant through the cooling circuit; and a radiator which is serially connected to the cooling systems in the cooling circuit and has a refrigerant outlet from which a refrigerant is supplied. The serially-connected cooling systems are arranged in a manner such that heat resisting allowable temperatures, assigned to the electric devices which respectively correspond to the cooling systems, increase from the cooling system closest to the refrigerant outlet to the cooling system farthest from the refrigerant outlet in the cooling circuit, wherein each heat resisting allowable temperature is the maximum temperature at which the relevant electric device can operate.

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： A failure diagnosis apparatus for a temperature sensor which detects a temperature that changes depending on an operating condition of an internal combustion engine. Determining that the temperature sensor fails, if the execution condition of the failure determination is satisfied and a temperature difference between the maximum temperature and the minimum temperature detected by the temperature sensor in the determination period, is less than a failure determination threshold value, when the starting of the engine in the preceding engine operation cycle was a cold start. Alternatively, determining that the temperature sensor fails, if the execution condition is satisfied, the temperature difference between the maximum temperature and the minimum temperature is less than the failure determination threshold value, and an engine stop period in the preceding engine operation cycle is longer than a failure determination permission time period, when the starting of the engine in the preceding engine operation cycle was not a cold start.

摘要： An atmospheric pressure estimating apparatus which estimates an atmospheric pressure applied to a calculation of control parameters of an internal combustion engine, is provided. An estimated intake air control valve passing air flow rate is calculated based on the estimated atmospheric pressure, the detected intake pressure, and the detected intake air control valve opening. The estimated atmospheric pressure is updated so that the estimated intake air control valve passing air flow rate coincides with the detected intake air control valve passing air flow rate. The estimated intake air control valve passing air flow rate is calculated using the updated estimated atmospheric pressure. The update of the estimated atmospheric pressure and the calculation of the estimated control valve passing air flow rate are sequentially performed. Consequently, the estimated control valve passing air flow rate follows the intake air flow rate, and the estimated atmospheric pressure follows the atmospheric pressure.
