Title:
FUEL INJECTION CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2014/091722
Kind Code:
A1
Abstract:
This fuel injection system is provided with first injection valves (21) that inject a fuel gas, a pressure-regulating valve (60) that reduces the pressure of the fuel gas supplied to the first injection valves (21) to a preset pressure, and a main tank stop valve (44) and a cutoff valve (45) disposed on the upstream side of the pressure-regulating valve (60). When requested to start an engine (10) using the fuel gas, a control unit (80) controls the opening timing of the main tank stop valve (44) and the cutoff valve (45) with respect to the start request timing of the engine (10) according to a prestart pressure, which is the pressure of the fuel gas being supplied to the first injection valves (21) at the time of the request.
