Title:
CONTROL APPARATUS FOR AN INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2013/099094
Kind Code:
A1
Abstract:
A fuel injection valve (14) of an engine (10) is connected via a gas passageway to a gas tank which stores gas fuel under high pressure. In the gas passageway, a pressure reducing valve (40) is provided as a pressure adjustment part which adjusts the supply pressure of gas supplied to the fuel injection valve (14). An ECU (50) detects the tank pressure, which is the pressure within the gas tank (30), and when the detected tank pressure has dropped below a predetermined reduction criteria value, restricts a target gas pressure, which is the target value of the gas supply pressure, on the basis of the detected gas tank pressure. Further, when the target gas pressure is restricted, the timing of the fuel injection at the fuel injection valve (14) is advanced compared to that of a standard timing which is set when the target gas pressure is not restricted.
