Abstract
A fuel injection device comprises an air valve located upstream of an operator actuated throttle in the air intake passage. The air valve is actuated by airflow through the passage and opens in proportion to the increase in the flow rate of air. Fuel under pressure is delivered to the air passage through an electrically energized injector valve. A metering system which is sensitive to the position of the air valve supplies the valve with repetitive electrical pulses during normal operation of the engine. During cranking, the metering system delivers a continuous energization signal to the valve for maintaining it permanently open. The pressure of the fuel delivered to the valve is substantially decreased during cranking, i.e. as long as a continuous energization signal is delivered to the injector valve.
