Title:
FUEL SUPPLY CONTROL DEVICE OF AUXILIARY CHAMBER TYPE GAS ENGINE
Document Type and Number:
Japanese Patent JP2014185574
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a fuel supply control device of an auxiliary chamber type gas engine which can supply gas fuel timely.SOLUTION: A fuel supply control device 100 includes: an auxiliary chamber fuel supply valve 18 which supplies gas fuel to an auxiliary chamber 24; a check valve 19 which is interposed between the auxiliary chamber fuel supply valve 18 and the auxiliary chamber 24 and blocks back flow from the auxiliary chamber 24; a valve state detection device 51 which detects movement state of the check valve 19; a rotation angle detection device 56 which detects a rotation angle in an engine cycle; and a control device 60 which decides a movement command value of the auxiliary chamber fuel supply valve 18. The control device 60 measures actual movement state of the check valve 19 corresponding to a rotation angle based on a signal from the valve state detection device 51 and the rotation angle detection device 56 and corrects the movement command value of the auxiliary chamber fuel supply valve 18 so as to approximate the measured actual movement state to a target movement state.
