Abstract

A diesel engine including an auxiliary or swirl chamber provided in the cylinder head and in communication with a main combustion chamber. The auxiliary chamber is defined in a shell structure which is located in the cylinder head and provided with a heat insulating structure. The engine includes an exhaust gas recirculating system in which the exhaust gas recirculation ratio, expressed as a percentage, is controlled in a range between (60-100.times.1/.lambda.) and (140-210.times.1/.lambda.), where .lambda. is the excess air ratio.
