Abstract
Apparatus constituting part of an induction and fuel delivery system for a cylinder of a piston internal combustion engine comprising a small cyclone into which is tangentially discharged a flow of heated air to generate a sustained vortex of high rotational speed; a modulatable fuel injector delivering a flow of atomised fuel into said small cyclone wherein it underdoes flash evaporation and energetic mixing; a delivery duct connecting said small cyclone to the inlet tract of said cylinder wherein said vortex fuel-air mixture is mixed with heated induction air; and means to prevent overheating of said modulatable fuel injector.

Apparatus constituting part of an induction and fuel delivery system for a cylinder of a piston internal combustion engine comprising a small cyclone into which is tangentially discharged a flow of heated air to generate a sustained vortex of high rotational speeds;
- a modulatable fuel injector delivering a flow of atomised fuel into said small cyclone wherein it underdoes flash evaporation and energetic mixing;
- a delivery duct connecting said small cyclone to the inlet tract of said cylinder wherein said vortex fuel-air mixture is mixed with induction air;
- and means to prevent overheating of said modulatable fuel injector.
A method of providing fuel-air mixture to a cylinder of a piston internal combustion engine comprising tangentially discharging a flow of heated air into a small cyclone to generate therein a sustained vortex of high rotational speed;
- delivering from a modulatable fuel injector a flow of heated, atomised fuel into said small cyclone wherein it underdoes flash evaporation and energetic mixing;
- discharging said vortex fuel-air flow via a delivery duct into the inlet tract of said cylinder wherein said vortex fuel-air mixture is mixed with heated induction air.
