過給装置。 A third valve is provided in the combustion chamber along with the intake and exhaust valves, a branch passage is provided in which the combustion chamber communicates with the high pressure air source and the exhaust passage in parallel through the third valve, and a passage is switched to the branch part of the branch passage. While the valve is provided, there is also a means for detecting the operating state of the engine and a third valve when the engine is running at low speed.
A control means that opens the valve for a predetermined period at the beginning of the compression stroke and switches the passage switching valve to the high-pressure air source side; and a control means that opens and closes the third valve in synchronization with the exhaust valve when the engine is at high speed, and switches the passage switching valve to the exhaust passage side. A supercharging device for an internal combustion engine, characterized in that it is provided with a control means for switching to.
