摘要： An evaporative fuel-processing system for an internal combustion engine includes an evaporative emission control system having a canister, a first passage connecting between the canister and a fuel tank, a second passage connecting between the canister and the intake system of the engine, and a purge control valve arranged across the second passage, a drain shut valve for opening and closing an inlet port of the canister, and pressure sensors for detecting pressure within the evaporative emission control system. The evaporative emission control system is negatively pressurized by introducing negative pressure from the intake system into the evaporative emission control system by opening the purge control valve and closing the drain shut valve, to thereby bring the evaporative emission control system into a predetermined negatively pressurized state, and then closing the purge control valve to complete the negative pressurization. Presence/absence of a leak from the system is detected based on a rate of decrease in negative pressure within the evaporative emission control system after the closing of the purge control valve. The leak detection is started when the pressure within the evaporative emission control system becomes substantially equal throughout the system after the completion of the negative pressurization.

摘要： A tank internal pressure-detecting device for an internal combustion engine having an evaporative emission control system for controlling purging of evaporative fuel generated in a fuel tank thereof into an intake system thereof. An ECU interrupts purging of evaporative fuel by the evaporative emission control system for a predetermined period of time after the engine is started. The ECU causes control valves of the evaporative emission control system to open the interior of the fuel tank to the atmosphere, and stores a value of pressure within the fuel tank detected by a tank internal pressure sensor as a reference value while the purging is being interrupted and at the same time the interior of the fuel tank is opened to the atmosphere. The ECU corrects an output value of the tank internal pressure sensor, based upon the reference value stored.

摘要： A failure-detecting device detects failure of a tank internal pressure sensor for an internal combustion engine. The tank internal pressure sensor is provided in a fuel tank for detecting pressure within the fuel tank. The failure of the tank internal pressure sensor is detected by detecting an amount of variation in an output from the tank internal pressure sensor occurring within a predetermined time period elapses after the start of the engine and determining that the tank internal pressure sensor is abnormal when the amount of variation is below a predetermined value upon the lapse of the predetermined time period. A fail-safe device inhibits abnormality diagnosis of the evaporative emission control system when it is determined that the tank internal pressure sensor is abnormal. A fail-safe device performs a fail-safe action including at least opening a control valve arranged at an air inlet port of a canister for closing and opening the air inlet port, when it is determined that the tank internal pressure sensor is abnormal.

摘要： Misfire detection system for an internal combustion engine. If misfire is found to occur due to vapor lock temporarily happening, it will erroneously be judged that the structure of the engine or the fuel supply system is out of order. However, vapor lock is an interruption of the flow of fuel in a gasoline engine caused by formation of vapor or gas bubbles, and does not mean the engine or the fuel supply system is degraded in its structure. On the contrary, if misfire is detected in such situation, the misfire detection degrades the reliability of the system. The misfire detection is therefore inactivated during conditions in which vapor lock is liable to occur, by discontinuing the detection, or by deliberately deeming no misfire to occurs even if it is so detected. Alternatively, the reference level for misfire detection is raised during such conditions.
摘要翻译：内燃机失火检测系统。如果由于蒸气锁暂时发生发生失火，将错误地判断发动机或燃料供应系统的结构是否有故障。然而，蒸气锁是汽油发动机由蒸气或气泡形成引起的燃料流的中断，并不意味着发动机或燃料供应系统的结构降低。相反，如果在这种情况下检测到失火，则失火检测会降低系统的可靠性。因此，在容易发生蒸汽锁的情况下，通过中止检测，或者故意认为即使检测到不发生失火也会使失火检测失效。或者，在这种情况下提高了失火检测的参考水平。

摘要： An evaporative fuel-processing system for an internal combustion engine, in which a first control valve is arranged across an evaporative fuel-guiding passage extending from a fuel tank to a canister, a second control valve across a purging passage extending from the canister to the intake system of the engine, and a third control valve at an air inlet port of the canister, respectively. An ECU generates operation command signals to the first to third control valves for closing or opening the same. The ECU is responsive to an output from a tank internal pressure sensor which detects pressure within the fuel tank and the operation command signals, for detecting an abnormality in operation of a predetermined one of the first to third control valves.

摘要： A combustion state-determining system for an internal combustion engine has an ECU which determines a misfiring state of the engine, and calculates a misfiring rate of the engine, based on the result of the determination of the misfiring state. A catalyst temperature sensor detects the temperature of a catalytic converter as the exhaust system temperature, and the ECU determines the combustion state of the engine, based on the detected exhaust system temperature and the calculated misfiring rate. A combustion state control system restrains the output from the engine, based on the determination result of the combustion state-determining system.
