<P>PROBLEM TO BE SOLVED: To effectively perform supercharging assist by a device stored in a small space. <P>SOLUTION: Gas fuel such as hydrogen is injected from a fuel injection valve 10 to an intake system of an engine 1. A decompression regulator 13 is arranged in a fuel supply route 12 connecting a fuel injection valve 10 and a fuel tank 11 storing gas fuel under a compressed condition. Gas fuel is supplied to an exhaust passage 7 at an upstream side of a turbine wheel 5b of the exhaust turbocharger 5 by a supercharging assist device 20. The assist fuel passage 21 to the supercharging assist device 20 is branched from a part between a regulator 13 and the fuel tank 11 out of the fuel supply route 12. <P>COPYRIGHT: (C)2009,JPO&INPIT |
