<P>PROBLEM TO BE SOLVED: To provide a supercharging assisting device of an internal combustion engine capable of quickly opening-closing a shutter type switching valve, and shortening pressure accumulating time by reducing an on-vehicle air tank. <P>SOLUTION: The switching valve 20 is formed of a slide type shutter valve, and an air cylinder 11 is used for opening-closing operation of the switching valve 20. The inside of the air tank 51 is partitioned into an upstream chamber 52 on the compressor 50 side and a downstream chamber 53 on the switching valve 20 side by a partition plate 54. The upstream chamber 52 and the downstream chamber 53 are communicated by arranging an orifice 56 in the partition plate 54. The upstream chamber 52 and the air cylinder 11 are connected by an air cylinder driving air supply pipe 13, and the air cylinder driving air supply pipe 13 is connected with an opening-closing valve 14 for supplying compressed air of the upstream chamber 53 to the air cylinder 11 in transient operation. <P>COPYRIGHT: (C)2012,JPO&INPIT |
