ABSTRACT:
A squish jet arrangement for an internal combustion engine is positioned on a piston member or cylinder head member thereof. A substantially cylindrical bowl opens onto the face of the member. At least one pair, and preferably a plurality of pairs, of squish jet passages are arranged to direct flows of gasses tangentially into the bowl. As first ones of the pairs of squish jet passages lie in a lower transverse plane than second ones of the pairs, a counter-rotating, bi-level swirl can be produced by the squish jet outlets. A squish jet arrangement is also provided with outlets of squish jet passages spaced above a lower surface of a bowl, and directed to eject coplanar flows of gasses therefrom, which intercept one another.
