Automotive Gasoline Injection 560321

APPLICATION of injection equipment, especially designed for gasoline, to the stock V-8 passenger-car engine is described here.
The port-injection system tested basically consists of an injection pump driven at half crankshaft speed, a mixture control governing the pump setting, a motor-driven fuel supply pump maintaining fuel pressures above the vapor pressure of gasoline, and the associated nozzles and fuel filter.
Advantages of converting a stock carbureted engine to gasoline injection include 10% greater full-throttle horsepower output, a minimum decrease of 500 rpm in torque peak position, 5–15% more miles per gallon, and the use of fuels having higher vapor pressures and end points.
