FUEL MIXTURE ENRICHMENT SYSTEM FOR INTERNAL COMBUSTION ENGINE |
摘要 |
A fuel priming system for spark ignited internal combustion engines includes a manually actuated plunger pump for delivering liquid fuel from a tank to a reservoir chamber formed in part by a flexible diaphragm. A fuel injection passage leads from the reservoir chamber through a flow restricting orifice to an injection point formed in the engine intake air flow passage downstream of the carburetor venturi. The injection system provides for enriching the fuel-air mixture during cold starting while minimizing the chance of engine flooding. The finite fuel volume in the reservoir chamber also provides a sufficient quantity of fuel for automatic control of a rich fuel-air mixture during engine warm-up. |
