Abstract: A fault determining apparatus for a variable valve timing mechanism is provided for shortly and accurately determining a fault even at low oil temperatures. The mechanism is driven by an oil pressure to change a cam phase of an intake cam and/or an exhaust cam with respect to a crank shaft of an internal combustion engine, thereby controlling the actual cam phase to reach a target cam phase. The apparatus has a fault determining routine executed by an ECU (electric control unit) for determining that the mechanism is faulty when a cam phase difference between the target cam phase and the actual cam phase is not within a predetermined range, an oil temperature sensor for detecting the temperature of the working oil, and a correcting routine executed by the ECU for correcting the predetermined range in an increasing direction when the detected oil temperature is low.

The pressure in the canister is reduced to a pressure which is lower than the atmospheric pressure in the condition where a valve closing command signal for the bypass valve is output.

Abstract: A system for discriminating malfunction of a radiator of an internal combustion engine, in which conditions for execution of malfunction discrimination of the radiator are decided to be established, when a decline amount of outside air temperature is less than a threshold value, and the malfunction discrimination is conducted by comparing an estimated and detected coolant temperatures with predetermined values. In the system, making the decision that the conditions are not established is prevented, utilizing a parameter related to a quantity of intake air. With this, it becomes possible to inhibit decisions finding that the conditions are not established in certain cases in which such a decision would ordinarily be unreasonably made, such as when the internal combustion engine is started while still insufficiently soaked, etc.

Abstract: A failure diagnosis apparatus for diagnosing a failure in an evaporative fuel processing system is disclosed. The evaporative fuel processing system has a fuel tank, a canister containing an adsorbent for adsorbing evaporative fuel generated in the fuel tank, an air passage connected to the canister and communicating with the atmosphere, a first passage for connecting the canister and the fuel tank, a second passage for connecting the canister and an intake system of an internal combustion engine, a vent shut valve for opening and closing the air passage, and a purge control valve provided in the second passage. The purge control valve and the vent shut valve are closed when stoppage of the engine is detected and it is determined whether there is a leak in the evaporative fuel processing system according to the detected pressure in the evaporative fuel processing system during a predetermined determination time period after closing the purge control valve and the vent shut valve.

Abstract: There is provided a leakage determination system for an evaporative fuel processing system, which, even when pressure within the evaporative fuel processing system is temporarily increased e.g. due to an increase in the amount of generation of evaporative fuel in a fuel tank, is capable of performing an accurate leakage determination by eliminating the influence of the temporary rise in the pressure within the evaporative fuel processing system on the leakage determination. A pressure sensor detects pressure within the evaporative fuel processing system. Negative pressure is introduced from the intake system into the evaporative fuel processing system, whereby the pressure within the evaporative fuel processing system is reduced until the detected pressure becomes equal to a predetermined negative pressure. After the pressure reduction, the negative pressure is introduced from the intake system into the evaporative fuel processing system under predetermined conditions.

The evaporative fuel processing system includes a fuel tank, a canister for trapping evaporative fuel generated in the fuel tank, a charging passage for connecting the fuel tank and the canister, an on-off valve provided in the charging passage for opening and closing the charging passage, and a pressure sensor provided in the charging passage at a position between the on-off valve and the fuel tank. A pressure in the canister is reduced to a pressure which is lower than the atmospheric pressure in the condition where the on-off valve is open. The on-off valve is closed at the time of completion of the pressure reduction, and it is determined that the charging passage is clogged between the pressure sensor and the fuel tank, when an amount of change in pressure detected by the pressure sensor is less than a predetermined change amount after closing the on-off valve.
