    摘要: An object of this invention is, with respect to a torque-demand-control type controller that subjects two kinds of actuators provided upstream and downstream in an intake passage to coordinated operations based on a requested torque for an internal combustion engine, to enable realization of a pulse-like torque change in a torque decreasing direction that is requested, for example, when performing an upshift operation in an electronically controlled automatic transmission. To achieve this object, according to a controller for an internal combustion engine of this invention, when a pulse component in a torque decreasing direction is included in a requested torque, a second requested torque that does not include the pulse component is generated. In this case, a first actuator provided on the downstream side in the intake passage is operated based on the requested torque. On the other hand, although a second actuator provided on the upstream side in the intake passage is operated based on the requested torque when there is not a valid value of the second requested torque, the second actuator is operated based on the second requested torque when there is a valid value of the second requested torque.

    摘要: A control system 14 and method for preventing exhaust gases from entering an intake manifold 26 of an engine 21 after engine shutdown is provided. The engine 12 includes a valve controlling air flow into the intake manifold 26. The method includes determining when the engine 12 has been shutdown. The method further includes opening the valve for a predetermined amount of time after the engine shutdown to allow air at ambient atmospheric pressure to communicate with the intake manifold 26. Thus, a relatively high air pressure in an intake manifold 26 prevents exhaust gases from migrating into the intake manifold 26 which reduces a subsequent engine crank period.

    摘要: A control apparatus for an internal combustion engine comprises a throttle upstream pressure estimation unit which calculates, based on an AFS intake air amount from an AFS and an intake manifold pressure, an average density ρave(n) in a region combining a supercharged portion from a downstream of a compressor to an upstream of a throttle valve and an intake manifold, and estimates a throttle upstream pressure based on the intake manifold pressure and the average density ρave(n). Further, the throttle upstream pressure estimation unit learns a relationship between a throttle opening degree and an effective opening area to correct a throttle upstream pressure estimated value (estimated P2) based on a range of a throttle opening degree learning value, the throttle opening degree learning value, and a dispersion of the actual throttle opening degree error.
