PROBLEM TO BE SOLVED: To provide a diesel engine capable of enhancing warming up performance.SOLUTION: A diesel engine has a three-way valve 14 which is installed in an auxiliary cooling circuit 9 between a retarder 8 and a radiator 4 and diverges a flow of cooling water 2 from the auxiliary cooling circuit toward a side of an intake port of a water pump 5 in a main cooling circuit 7. In response to a request for starting up an engine body 1, an ECU 17: starts up the engine body 1 and the retarder 8; and controls the three-way valve 14 in a manner that switches a flow direction of the cooling water toward the side of the intake port of the water pump 5 when a temperature of the cooling water 2 at an exit of the engine body 1 is not more than a valve opening temperature S.SELECTED DRAWING: Figure 2

    【課題】従来よりも暖機を促進することができるディーゼルエンジンを提供する。【解決手段】副冷却回路9におけるリターダー8とラジエータ4との間に、主冷却回路7におけるウォータポンプ5の吸入口側へ分岐する三方弁14を介設して、ECU17は、エンジン本体1の始動要求があったときは、エンジン本体1を始動するとともにリターダー8を起動する一方で、エンジン本体1の出口における冷却水2の温度が開弁温度S未満のときは、三方弁14の流路をウォータポンプ5の吸入口側へ向けて切り換える制御を行う。【選択図】図2
