AIR CELL COMBUSTION CHAMBER REDUCES DIESEL SOOT

This article describes a direct injection diesel engine with an air cell above the regular combustion chamber. Unused air is stored in the cell during the compression stroke and initial combustion phase; after fuel injection the air is reinjected into the combustion chamber to stir the stagnating flame. It thus promotes soot oxidation by raising oxygen partial pressure around the particles. A variable unit, featuring a needle valve at the air cell's entrance, is proposed for benefits throughout the operating range.
