Abstract
PURPOSE: To prevent conduit pipes from oil leakage and uniform the distribution of fuel to all cylinders by providing a fuel injection device in the suction system of an engine and a sucking-back chamber changeable in its capacity in a fuel conduit pipe concentration part.
CONSTITUTION: Each fuel conduit pipe 13 from a fuel conduit pipe concentration part 12 is connected to each suction branch pipe 3 in a multi-cylinder engine 1. The fuel in the tank 5 is introduced into the concentration part 12 via a pump 16, a regulator 17, and an electromagnetic fuel injection valve 11 controlled for opening and closing by a control circuit 18. Meanwhile, a sucking-back chamber 21 provided with a sucking-back valve 22 is connected to the concentration part 12, and the sucking-back valve 22 is connected to a control circuit 18 and retreated when injection is off in the injection valve 11. Consequently, the capacity of the chamber 21 is increasd to reduce the fuel pressure in routes in the system. At the time of injection, the valve 22 is pushed ahead to increase its fuel pressure.
