FAST START FUEL SYSTEM FOR AN INTERNAL COMBUSTION ENGINE

摘要

A fuel delivery system for an internal combustion engine. The fuel delivery system includes a carburetor housing having an air passage (30) with a throttle valve (35) disposed therein. The air passage has an inlet (31) and an outlet (32). The outlet is in communication with the engine. Means are provided for simultaneously opening the throttle valve, restricting air flow into the air passage and injecting a predetermined volume of fuel into the air passage before the engine is started. Other means are provided for automatically adjusting the restriction of air flow and the predetermined volume of fuel to compensate for changes in ambient temperature.
