PURPOSE:To have a light and simple variable chamber by making it in bellows construction, and by allowing its volume to change according to the operating condition of the engine. CONSTITUTION:With rotation of engine 1, a controller 14 shall calculate the set volume Vop on the basis of the number of revolutions sensed by a rotary sensor 13 and the volume of a variable chamber 5 sensed by a volume sensor 12. Inlet and outlet of a solenoid valve 11 are opened and closed according to the result of said calculation so as to elevate or sink a piston 8 in the cylinder 10, whereby the volume of the variable chamber 5 is changed according to the number of engine revolutions to serve for inertia supercharging in compliance with the current number of revolutions. The variable chamber 5 is formed in bellows from rubber etc. and fitted in communication with the suction manifold 2. |
