摘要： An engine wherein a target air-fuel ratio is changed over according to the running conditions is provided with a device for computing a target throttle opening area based on the accelerator operation and a selected air-fuel ratio. It also includes a device for correcting the throttle opening such that the throttle opening area is equal to a target throttle opening area, a device for computing a fuel amount to be provided to the engine based on the target air-fuel ratio, intake air volume and engine speed, and a device for regulating the fuel supply to the computed amount. In this way, the throttle valve opening is corrected when the air-fuel ratio is changed, fluctuations in the torque generated by the engine are smoothed out, and torque shock due to the air-fuel ratio change-over is thereby prevented.

摘要： To achieve an intermediate lock state in a short period when an engine is stopped and improve the accuracy of confirmation of the intermediate lock state, an engine valve timing control apparatus includes a variable valve timing mechanism configured to vary engine valve timing, and an intermediate lock mechanism configured to restrict relative rotation positions of a first and a second rotor of the valve timing mechanism at an intermediate lock position for starting the engine. Upon detection of an engine stop request, the valve timing mechanism and the intermediate lock mechanism are driven and controlled for establishing an intermediate lock state. When a predetermined period from detection of the engine stop request has expired without detecting the intermediate lock state within the predetermined period, an engine stopping process is executed. Even after the engine stopping process has been executed, monitoring of the intermediate lock state is continued.

摘要： A controller (70) controls the boost pressure of an internal combustion engine (60) comprising two intake/exhaust units, each intake/exhaust unit comprising a turbocharger (10) which supercharges intake air in an intake passage (20) using exhaust energy in an exhaust passage (30), and an exhaust gas recirculating device (40, 41) which recirculates a part of the exhaust gas in the exhaust passage to the intake passage. The controller (70) calculates an opening difference between valves in the two units (S121), and controls a regulating device (13) in each of the two units on the basis of this opening difference (S123-S125). As a result, the boost pressures of the turbochargers (10) match, and hence an equal amount of NOx can be discharged from each exhaust passage (30), and the NOx can be purified favorably by a catalyst.

摘要： A particulate deposit amount Spm on a particulate filter disposed in an exhaust passage is estimated during a usual period different from a regeneration period of the particulate filter and during the regeneration period thereof respectively.An increase value Dpm per unit time of the Spm during the usual period is estimated based upon an engine operating condition and a total amount of the Spm is determined by integration thereof (S15, 16).On the other hand, a particulate deposit amount Spm decreasing by burning during the regeneration period is determined by, one by one, subtracting a decrease value Dpm per unit time estimated based upon a particulate deposit amount Spmi that is determined by the above integration at a starting point of the regeneration period from the Spmi (S12, 17).

摘要： The internal combustion engine (1) has a throttle (23) for controlling an intake air amount and performs start-up through cranking. The starter switch (36) detects cranking initiation, and the crank angle sensor (33, 34) detects the number of revolutions of the engine. The controller (31) drives the throttle (23) in a closed position along with the cranking initiation. The controller (31) can obtain both the intake negative pressure for promoting vaporization of fuel and the intake air amount necessary to maintain the idle rotation speed by counting the number of strokes or the number of revolutions of the internal combustion engine (1) from the cranking initiation and opening the throttle (23) from the closed position as the count number reaches a predetermined number.
