    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.

    摘要: In an intake control system for a general-purpose engine, comprising: a motor which is attached to a first side wall, supporting one end portion of a valve shaft of a throttle valve, of a throttle body, and which drives the throttle valve to be opened and closed; a sensor unit which is attached to a second side wall supporting the other end portion of the valve shaft, and which detects an opening degree of the throttle valve; a fuel injection valve which is attached to a third side wall integrally connecting upper end portions of the first and second side walls to each other, and through which a fuel is injected into the intake path at a position downstream of the throttle valve; and an electronic control unit which is attached to a fourth side wall facing the third side wall, the electronic control unit is connected to the motor, the fuel injection valve and the sensor unit with first, second and third conducting wires, respectively. Accordingly, it is possible to allow significant shortening of wires, which electrically connect intake control elements to each other, by completing the wiring only around the throttle body.
