ABSTRACT:
Method and apparatus for producing intense, consistent swirl and air-fuel-E.G.R.-vorticity charge uniformity without any net penalty in engine power, volumetric efficiency, or pumping work. Method and apparatus permit optimal swirl and turbulence for flame stability and fuel economy throughout the R.P.M.-load phase space of engine operation. Method and apparatus require no substantial changes in combustion chamber shape or basic engine structure. For spark fired engines, the method and apparatus permits operation at air-fuel-E.G.R.-intake manifold vacuum combinations having excellent fuel consumption characteristics combined with very low emissions of CO, HC, and NO. For diesel engines, the method and apparatus permits optimized swirl without the volumetric efficiency and pumping work penalties accepted with present art swirl inducing techniques.
