LIQUEFIED GAS FUEL SUPPLY DEVICE

摘要

Provided is a liquefied gas fuel supply device that, even if an accelerator is operated suddenly, can accurately follow said operation and stably carry out an appropriate engine operation. If it is determined from a supply flow volume determination value that a flow volume in a fuel supply pipe and/or the engine is anomalous, a valve opening/closing control means closes off a narrow openable/closeable channel by actuating an actuated valve in an electromagnetic valve device interposed between a fuel supply pump and the fuel supply pipe, thereby switching a main valve to a closed position and forcibly shutting off supply of a liquefied gas fuel from the fuel supply pump in a fuel tank to the fuel supply pipe. Thus, even if an excessive pressure differential arises due to sudden accelerator operation, said accelerator operation can be reliably followed and an appropriate engine operation can be stably carried out.
