摘要： When a leakage fault occurs in the evaporated fuel processing system of a fuel tank, a control system reliably prevents leakage of the evaporated fuel from the point where the leakage fault has occurred. The fuel tank and a canister are connected to each other via a charge passage having a bypass valve, and the canister and an intake passage of an engine are connected to each other via a purge passage having a purge control valve. When a leakage fault occurs in the fuel tank (or the charge passage upstream of the bypass valve), the bypass valve and the purge control valve are opened and an atmosphere release control valve provided on the canister, is closed. The closure of the atmosphere release control valve stops the negative intake pressure of the engine from being consumed by the intake of air through the atmosphere release control valve, and thus it is possible to efficiently prevent the evaporated fuel from leaking from the point where the leakage fault has occurred by effectively transmitting the negative intake pressure to the point where the leakage fault has occurred.

摘要： An abnormality diagnosis apparatus for performing a leak check of an evaporative fuel processing system which includes a fuel tank, a canister for storing evaporative fuel generated in the fuel tank, a purging passage for connecting the canister to an intake system of an internal combustion engine, and a purge control valve provided in the purging passage. A process of reducing the pressure in the evaporative fuel processing system is executed with a limited flow rate of gases passing through the purge control valve when performing the leak check in an idling condition of the engine. The limited flow rate is set to a value equal to or smaller than a predetermined flow rate which is smaller than the maximum flow rate applied to the leak check performed in operating conditions other than the idling condition. The leak check is performed on the basis of a change in the pressure in the evaporative fuel processing system after the pressure reduction process.

摘要： A control system is disclosed that accelerates the rise in temperature of a catalyst provided in an exhaust system of an internal combustion engine. The system increases the intake air amount after the engine starts and retards the ignition timing according to a rotational speed of the engine. In this control system, a failure of the catalyst temperature rise acceleration control is diagnosed according to the engine rotational speed and/or a retard amount of the ignition timing during the execution of the catalyst temperature rise acceleration control. The above failure may also be diagnosed according to at least one of the ignition timing and the engine rotational speed when decreasing the intake air amount during the execution of the catalyst temperature rise acceleration control. The above failure may also be diagnosed according to a detected catalyst temperature and an estimated catalyst temperature.

摘要： A highly stable engine failure diagnosing system free from influence of purging is presented. A monitoring apparatus for monitoring a fuel feed system of an internal combustion engine is provided with an A/F ratio detector and an A/F ratio controller for performing feedback control of the A/F ratio. An A/F ratio feedback coefficient is calculated according to the output of the detector. A malfunction determination parameter is calculated based on the coefficient. A purging is suspended when the parameter reaches a first decision value. The monitoring is suspended when the parameter reaches a second decision value in a purge cutting state. A value of the malfunction determination parameter it would take if the purge cut was not carried out is estimated using the value when the parameter reached the first decision value. The monitoring is resumed when the estimated value of the malfunction determination parameter reaches the second decision value.

摘要： There is provided a failure determination apparatus which is capable of determining the failure of a temperature sensor promptly and correctly regardless of environmental conditions at the start of an internal combustion engine. An ECU calculates an operation progress parameter indicative of a degree of progress of operation of the internal combustion engine from the start thereof. A RAM of the ECU stores a value of the temperature detected by the temperature sensor at a stoppage of the engine. Further, the ECU measures a stop time period from the stoppage to a start of the engine, and determines that the temperature sensor is faulty, when the difference between a value of the temperature detected by the temperature sensor at the start of the present operation of the engine and the value of the temperature stored in the RAM is equal to or smaller than a predetermined reference value on condition that the operation progress parameter calculated during the immediately preceding operation of the engine is larger than a predetermined value, and that the stop time period before the present operation of the engine is longer than a predetermined time period.

摘要： A determination as to whether or not the absolute value PCHK of the deviation between a detection value PTANK of a pressure sensor and its average value PTANKAVE exceeds a predetermined pressure DLEAKCHK is repeated within a predetermined time TINTVAL. The number of times the absolute value PCHK has exceeded the predetermined pressure DLEAKCHK is measured on a failure determination counter C91BNG. When the value of the counter C91BNG exceeds a determination threshold value 91BJVD, it is determined that the pressure sensor fails (time t10).
