ABSTRACT:
A fuel injection system having a fuel distributor which is connected to a fuel supply tube. The main fuel nozzles are fitted into openings in the lower surface of the fuel distributor and holes in the intake manifold near the main combustion chambers. A holding member supports the mid portion of the fuel nozzles and is connected to the fuel distributor. A fuel branching member is connected to the upper surface of the fuel distributor to supply fuel to the sub fuel injection nozzle. A cap seals the second end of the branched fuel passage from the atmosphere. An accommodating chamber is formed within a holding cylinder which is fitted about the leading end portion of the sub fuel injection nozzle. A fuel mixer is fitted within the accommodating chamber to emulsify the fuel. The emulsion is then injected into the unit sub intake passage through an emulsion tube. A holding member retains the sub fuel injection nozzle about its mid portion and is attached to the fuel branching member. The fuel branching member is attached to the fuel distributor to securely mount the sub fuel injection nozzle. A regulator valve is attached to the branched fuel passage to regulate the fuel pressure of the main injection nozzles and the sub injection nozzles.
