摘要： A stop control system for an internal combustion engine, which is capable of accurately stopping a piston at a predetermined position during stoppage of the engine while preventing occurrence of untoward noise and vibration. After stopping the engine 3, the stop control system 1 for the engine 3 according to the present invention executes a first stage control (step 34) in which a throttle valve 13a is controlled to a first stage control target opening degree ICMDOFPRE smaller than a second predetermined opening degree ICMDOF2, in order to stop the piston at the predetermined position, before executing a second stage control (step 42) in which the throttle valve 13a is controlled to the second predetermined opening degree ICMDOF2. Further, the stop control system 1 stabilizes initial conditions at the start of the second stage control by setting a first stage control start rotational speed NEICOFPRE and a first stage control target opening degree ICMDOFPRE according to a change in a corrected target stop control start rotational speed NEICOFREFN (steps 71 and 85).

摘要： A fuel supply control system for an internal combustion engine has an exhaust gas-purifying device arranged in the exhaust system of the engine. When a predetermined high load condition of the engine is detected, an amount of fuel supplied to the engine is increased. Temperature values indicative of the temperature of the exhaust gas-purifying device are stored and a stored temperature value is read out according to operating conditions of the engine. A correction coefficient for correcting the read-out temperature value is determined, and the temperature of the exhaust gas-purifying device is estimated based on the read-out temperature value and the determined correction coefficient. When the predetermined high load condition is detected and at the same time the estimated temperature is higher than a predetermined temperature value, the amount of fuel supplied to the engine is actually increased.

摘要： An evaporative fuel-processing system for an internal combustion engine includes a canister, a charging passage extending between the canister and a fuel tank, a purging passage extending between the canister and the intake system of the engine, an open-to-atmosphere passage for relieving the interior of the canister to the atmosphere, a charge control valve for opening and closing the charging passage, a purge control valve for opening and closing the purging passage, a vent shut valve for opening and closing the open-to-atmosphere passage, and a pressure sensor for detecting pressure within the charging passage. When the engine is in a predetermined operating condition, the interior of the fuel tank is negatively pressurized into a predetermined negatively pressurized state by opening the purge control valve and the charge control valve and closing the vent shut valve. When a predetermined time period has elapsed from the start of the negative pressurization before the interior of the fuel tank is set to the predetermined negatively pressurized state, the purge control valve and the charge control valve are closed, and an abnormality of the fuel tank is determined based on the pressure detected by the pressure sensor immediately before and after the closing of the purge control valve and the charge control valve.

摘要： An evaporative emission control system for an internal combustion engine has a purge control valve arranged in a purging passage connecting between a canister and an intake passage of the engine. The evaporative emission control system has a self-diagnosis function of determining whether the evaporative fuel emission control system is normal or abnormal from a change in a value of a parameter measured based on an output from an exhaust gas component concentration sensor arranged in an exhaust passage of the engine, which change is detected when the opening of the purge control value is changed, and a variation in pressure within the intake passage at a location downstream of a throttle valve arranged therein when the opening of the purge control valve is changed.

摘要： An improved evaporative fuel-purging control system for controlling a purging flow rate which is controlled by a solenoid purge control valve regulated with a pulse waveform signal. As for the characteristic of the purge control valve, differing periods of the signal differentiates the control valve linearity of purging flow rate with respect to the signal duty ratio. To improve the linearity, the pulse waveform signal period which creates the substantial linearity is selected among preset periods periods according to the preset duty ratio which works as a threshold value.
