Object of the Invention: This invention relates to a diesel engine system. The object of this invention is to provide a diesel engine system which can cool a DEF injector even after the engine is stopped. Outline of the Invention: With reference to Fig. 1, the diesel engine system has the following features: The diesel engine system (1) includes a diesel engine (2), a cooling water pump (2a) which is driven by the engine (2), a DEF injector (4) which has an injector cooling line (4a), a shunt tank (6) and a cooling water line (24) which connects the injector cooling line (4a) to the shunt tank (6). An auxiliary tank (26) is disposed in the cooling water line (24), and the auxiliary tank (26) is in a higher position than the shunt tank (6). The cooling water line (24) has a first part (24a) which connects the bottom of the auxiliary tank (26) to the injector cooling line (4a), and has a second part (24b) which connects the top of the auxiliary tank (26) to the shunt tank (6). |
