Abstract: A Divided Chamber combustion system comprising an energy-cell built in the bottom of a deep piston bowl; aligned in the cylinder's centerline; in fluid communication with the main combustion chamber through one main transfer passage disposed in its centerline and a plurality of auxiliary transfer passages circularly disposed around it. Each auxiliary transfer passage is at least inclined on a plane parallel to the cell's centerline. The injection nozzle, centrally-located in the fire deck of the cylinder head, includes a central pintle discharging fuel on the cylinder's centerline; and a plurality of small auxiliary orifices circularly surrounding the central pintle; discharging at a radial angle to the cylinder's centerline.

Abstract: An improved combustion system particularly for a larger type diesel engine featuring a prechamber with a generally cup-shaped bottom tip portion facing the engine's main combustion chamber and with a central transfer passage substantially aligned with the centerline of the prechamber and a plurality of additional transfer passages circumferentially arranged about the centerline of the prechamber. The improved complete combustion system uses a piston with a deep bowl formed in the piston crown into which the central transfer passage directs a strong direct charge of products of combustion from the prechamber.
