    摘要: A fuel control system for low pressure fuel injection apparatus on an internal combustion engine. An impulse fuel pump operated by pulsating crankcase pressure delivers a desired quantity of fuel to the fuel port of the engine combustion chamber, and returns the unused portion of its output to the fuel tank through a bypass line. The quantity of fuel diverted to the bypass is controlled by a pressure actuated valve as a function of crankcase pressure, which is determined by throttle demand and engine speed, and by the pump output, as measured by pressure in the fuel line.
