ABSTRACT:
A combustion system for internal combustion engines having a cylinder, at least one piston reciprocal in the cylinder and a combustion chamber with three regions for improving the combustion process, the piston having a piston head with an outer perimeter portion, a central recessed portion and a baffle with ports arranged over the recessed portion, the piston cooperating with a cylinder head or the head of an opposed piston to form an induction region that diminishes in volume as the piston approaches top dead center forcing gases in the combustion chamber through a central region defined primarily by the ports in the baffle to the dispersing region in the recessed portion of the piston, and a fuel injection system with an injector that delivers a staged series of fuel pulses in each cycle.
