Combustion chamber for diesel engines.

摘要

In a combustion chamber for diesel engines, to reduce the temperature of the wall surface contacted by the injected fuel (25), the inner wall includes a fuel-impinging area (12) formed of a metallic material, and a remaining area which at least partly is formed of a ceramic material (24) or the like heat-resisting material. The arrangement serves to achieve an effective exhaust gas clarification, including the minimization of NOx emission, and to realize increased power output and reduced fuel consumption of the engine.
