SINGLE POINT FUEL INJECTION SYSTEM

摘要

A combined fuel regulator and single point metering system comprises a diaphragm-type fuel regulator mounted at one end of a single point injector which carries a solenoid valve operated plunger movable with respect to a fuel distribution block located within the hollow interior of the injector base. The injector base is divided into a fuel outlet cavity located on one side of the fuel distribution block, and an air chamber located on the opposite side which is connected by a one-way valve to source of ambient air, and is also adapted for connection to a turbocharger or the like. The fuel distribution block is formed with a number of passages each directly connected to an air-fuel nozzle within which the fuel and air are intermixed for delivery through separate tubes to each of the cylinders of an internal combustion engine.
