ABSTRACT:
Internal combustion stratified-charge engine having within a cylinder thereof a variable volume space wherein a piston pursuant to an air intake stroke draws a stream of intake air through an entrance end of the combustion chamber and through such chamber into said variable volume space. The inner periphery of a sidewall of such chamber having a series of grooves which may score the head of a poppet type exhaust valve in such periphery and which contribute to stratification of a leading fuel-free mass of such stream and a fuel-containing trailing mass thereof into the variable volume space. A portion of such trailing fuel-containing mass remaining in the chamber and an adjacent portion thereof in the variable volume space adjacent to said chamber, and, pursuant to the ensuing compression stroke of the piston, the masses are caused to flow into the chamber in the reverse order of their formation with the fuel-containing mass compressed adjacent the entrance end of the chamber where combustion is initiated.
