エンジンの吸入空気量制御装置。A timing valve for opening and closing the intake passage is disposed in the intake passage on the upstream side of the intake valve, and a transition means for shifting the opening period of the timing valve is provided, and the transition means is activated by the intake pressure on the upstream side of the timing valve. In a diesel engine that is operated to close the timing valve earlier than the intake valve as the intake pressure is higher, there is a load detection means for detecting the load state of the engine, and an output from the load detection means, and the above-mentioned transition means at medium load. and intake pressure reducing means for reducing intake pressure in a combustion chamber by operating the timing valve so as to reduce the overlapping opening period between the timing valve and the intake volume.
