ABSTRACT:
A fuel injection system includes an injector having a fuel and air/gas mixing chamber that includes a normally closed injector valve, the chamber being for premixing fuel and air, complete with controls to provide a time interval between introduction of the fuel into the air chamber and the introduction of compressed air/gas to cause the injection event by opening of the valve to permit evaporation of the fuel whereby a premixed rich air/fuel mixture charge is discharged into the engine combustion chamber.
