摘要： A control system of an internal combustion engine in a vehicle, for improving the self-diagnosis accuracy and decreasing the frequency of stopping the self-diagnosis process, is disclosed. The system comprises a self-diagnosis section for executing self-diagnosis of the internal combustion engine; a load control section for controlling a load imposed on the internal combustion engine; and a normal driving control section for maintaining a normal driving state in which a variation of the load imposed on the internal combustion engine is suppressed, by operating the load control section while the self-diagnosis is being executed by the self-diagnosis section and while the current driving state of the vehicle is in a predetermined driving range.

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： When determining that a vehicle is not skidding, the ECU carries out tight corner control if vehicle speed is smaller than the upper limit value of the vehicle speed range corresponding to the starting state of the vehicle and the steering wheel turning angle of a steering wheel is greater than or equal to the minimum value of the steering wheel turning angle at which the tight corner braking phenomenon may occur. When determining that the vehicle is skidding, the ECU inhibits the tight corner control even if the vehicle speed is smaller than the upper limit value and the steering wheel turning angle is greater than or equal to the minimum value of the steering wheel turning angle at which the tight corner braking phenomenon may occur.

摘要： The present invention provides a scheme for determining an abnormality of an intake air system with higher accuracy in an engine an intake air amount is controlled by adjusting a lift amount of an intake valve. A throttle opening area is determined based on a current intake air amount. A feedback correction is performed on the throttle opening area. The feedback correction includes determining a correction amount of the throttle opening area such that the gauge pressure inside the intake manifold converges to a desired gauge pressure and then adding the correction amount to the throttle opening area. A feedback control is performed on an air-fuel ratio. The feedback control includes determining a correction amount of the air-fuel ratio based on a detection value of an air-fuel ratio detecting means provided in an exhaust manifold. An abnormality of the intake air system is determined during an idling operation based on the correction amount of the throttle opening area and the correction amount of the air-fuel ratio.
