FUEL FEEDING DEVICE FOR GAS ENGINE

摘要

PROBLEM TO BE SOLVED: To precisely detect the temperature and the pressure of actually injected fuel. SOLUTION: An injector 23 is provided to separately inject and feed fuel, consisting of compressed natural gas, to intake branches 13 respectively communicating with a plurality of cylinders. A fuel inlet pipe 28 to which fuel is fed is situated approximately at the central part in a longitudinal direction of an injector communicating gallery 24 to effect intercommunication between injectors 2. A fuel temperature sensor 29 to detect the temperature of fuel is situated at a connection part between a fuel inlet pipe 28 and an injector communicating gallery 24 and a fuel pressure sensor 35 to detect the pressure of fuel is situated between the two injectors 23 of the injector communication gallery 24 ion one side with the fuel inlet pipe 28 therebetween. According to the detecting values of the fuel temperature sensor 29 and the fuel pressure sensor, a fuel injection amount by the injector 23 is corrected and controlled.
