Title:
FUEL INJECTION DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2014/115510
Kind Code:
A1
Abstract:
In an engine (10), a gas fuel injection valve (21) is provided for each cylinder group having two cylinders each, said cylinders having a continuous combustion order. A distributor (24) is connected to each gas fuel injection valve (21) for each cylinder group, and a fuel-guiding pipe (23) is connected for each cylinder, to the distributor (24). Gas fuel injected from the gas fuel injection valves (21) is ejected to each intake section in the same cylinder group, via the distributor (24) and the fuel-guiding pipe (23). A control unit (60) calculates the amount of gas fuel required for two cylinders in the same cylinder group, and controls fuel injection by the gas fuel injection valves (21), for each cylinder group and on the basis of the amount required.
