PROBLEM TO BE SOLVED: To provide a fuel pressurizing device for a cylinder injection type gas fuel engine for restraining consumed energy. SOLUTION: The cylinder injection type gas fuel engine 1 in which gas fuel is injected from an injector 8 into a cylinder is provided with a fuel cylinder 10 storing the gas fuel to be supplied to the injector 8, a pressurization chamber 16 pressurizing the fuel cylinder 10, an oil pump 21 increasing pressure of the pressurization chamber 16, a power transmission mechanism 22 transmitting rotation of a wheel 4 of a vehicle to the oil pump 21, and a control unit 31 as a regenerative control means determining deceleration traveling time of the vehicle requiring pressurization of the fuel cylinder 10 and operating the oil pump 21. Thus gas fuel injection pressure of the injector 8 is secured. COPYRIGHT: (C)2005,JPO&NCIPI
