ABSTRACT:
A number of embodiments of combustion chamber configurations for internal combustion engines incorporating squish areas for promoting turbulence and rapid flame propagation in the main combustion chamber volume. A pre-combustion chamber volume is formed in at least one of the squish areas and communicates with the main combustion chamber volume through flow channels that are substantially unrestricted except when the piston is at its top dead center position for reducing pumping losses and insuring complete combustion within the squish area.
