Title:
GAS FUEL FEED DEVICE
Document Type and Number:
Japanese Patent JP3945066
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To smoothen the opening and closing of a valve by the pressure rise of gas fuel by detecting the pressure of the gas fuel force fed to a fuel injection means, and prohibiting the fuel cut by a fuel cut means, when the detected gas fuel pressure is a prescribed reference value or more.
SOLUTION: When on-state of an idle switch is determined in an ECU 20, it is judged whether or not a fuel cut is under execution. When the fuel cut is under execution, it is determined whether or not the rotating speed of an engine 12 is smaller than a first rotating speed reference value. When this determination is YES, and the change quantity of the engine rotating speed is a change quantity reference value or more, the fuel cut for stopping the fuel injection from an injector 22 is prohibited. When the change quantity of the engine rotating speed is less than the change quantity reference value, and it is determined that the pressure of the gas fuel detected by a pressure sensor 23 is a pressure reference value or higher, the fuel cut is prohibited in the same manner.
