ABSTRACT:
A diesel engine includes a variable swirl forming mechanism, an exhaust gas recirculation (EGR) control mechanism, and an injection timing control mechanism. The variable swirl forming mechanism forms strong, middle or weak air swirls in a combustion chamber according to engine loads and engine speeds. The EGR control mechanism recirculates a part of exhaust gas to the combustion chamber according to the engine loads and the engine speeds. The injection timing control mechanism advances or retards the injection timing according to the engine loads and the engine speeds.
