    Abstract: A difference is obtained between a cylinder pressure during the compression stroke when an exhaust gas recirculation control valve is opened, and a cylinder pressure during the compression stroke when the exhaust gas recirculation control valve is closed. An estimated value for this difference is set from a cylinder pressure detected under the closed conditions and an exhaust gas recirculation proportion. When the difference is smaller than the estimated value, it is assumed that the exhaust gas recirculation quantity is not changing in accordance with open/close control, and the occurrence of a fault in the exhaust gas recirculation unit is thus judged.

    Abstract: A exhaust gas recirculation control value is forcibly open/close controlled at the time of steady operation. An estimation of whether or not the actual exhaust gas recirculation quantity has changed with open/close control of the exhaust gas recirculation control valve, is then made based on whether or not a change in combustion pressure accompanying the open/close is a value estimated for the operating conditions.

    Abstract: An air fuel ratio control system is so arranged to restrain a undesired variation of an air fuel ratio due to an on off control of a canister purge and thereby prevent deterioration of an exhaust performance. When a purge cut valve is closed to cut off the canister purge, the control system changes a feedback air fuel ratio corrective factor ALPHA like a step change to a predetermined initial value EVALP# to meet a leaning change of the air fuel ratio caused by the purge cut. When the purge cut valve is opened to resume the canister purge, the control system meets an enriching change of the air fuel ratio caused by restarting of the purge by producing a step change in the corrective factor ALPHA to an initial value EALPHA.times.KEVAL# determined in accordance with a value EALPHA of the corrective factor ALPHA obtained immediately before the cutoff (KEVAL# is a constant).

    Abstract: A fuel injection amount calculation method calculates a fuel injection amount to an internal combustion engine of a vehicle. The method can include calculating a relative intake pressure which is a difference between an intake pressure peak of intake air upon intake starting of a cylinder of the internal combustion engine and an intake pressure bottom of the intake air upon intake ending. The method can also include calculating the fuel injection amount based on the relative intake pressure.

    Abstract: A fault sensing device for a vehicle includes a time measuring section functioning as a sleep mode while power to a controller is off. The time measuring section can measure a stop time of an engine, and can transmit information on the stop time to the controller when power to the controller is on. When the controller determines that a stop time of the engine is a predetermined time, the controller performs fault sensing for an oil pressure switch.

    Abstract: When cranking starts by turning on a starter switch 14, the ignition timing is first corrected to a fixed value on a retard side. When an IACV 6 reaches a fully opened position, the ignition timing is corrected to the retard side once, and thereafter corrected to an advance side. The correction to the advance side is performed in accordance with a difference between the number of idling target steps and the current number of steps, and the amount of advance correction is reduced as the difference is reduced. Upon completion of the initialization of the IACV 6, the ignition timing correction amount is then restored to the initial value by increasing the amount of advance by a predetermined amount in a stepwise manner.

    Abstract: A reverse rotation preventive device wherein an engine can be restarted without once stopping the vehicle even in the case where a reverse rotation preventive function is operated in response to momentary locking of a rear wheel. A plurality of reluctors are arranged at regular intervals, exclusive of a toothless part at one location with a crank pulse rotor rotated synchronously with a crankshaft of the engine, and a first and second pulse generators each of which outputs a pulse signal corresponding to the interval of the reluctors. Reverse rotation preventive means inhibits ignition of a spark plug by operating the reverse rotation preventive function when the interpulse time of the pulse signal exceeds a predetermined time and cancels the inhibition of the ignition when it is detected that a crankshaft is in normal rotation after the ignition is inhibited by the operation of the reverse rotation preventive function.
