AUTOMOTIVE FUEL SYSTEM

摘要

A PCV circuit for an internal combustion engine is modified to deliver the PCV fluid to an atomization chamber which also receives fuel from an electronic fuel injector tapped into the main vehicle fuel supply. The fuel from the injector is thoroughly vaporized in and/or immediately downstream of the chamber and conveyed to the vehicle intake manifold. A switch cuts off operation of the fuel injector at high load/high throttle setting conditions. The injector operates at a constant frequency with a selected ON time.
