Method and apparatus for 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 with a throttle valve disposed therein. A choke lever is movably mounted to the carburetor housing for restricting air flow into the air passage. A fuel injection device is provided for injecting fuel into the air passage before the engine is started. Movement of the choke lever to an engaged position simultaneously opens the throttle valve, restricts air flow into the air passage and activates the fuel injection device to inject a predetermined volume of fuel into the air passage. The air-flow restriction and the predetermined volume of fuel are adjusted to compensate for changes in ambient temperature.
