Internal combustion engine with heat accumulating device

摘要

An electronic control unit (ECU) (30) of an engine system (100) starts a control (preheat) for supplying heat reserving hot water stored in a heat accumulating device (21) to an engine (10) prior to an engine start. The ECU (30) determines a time for continuing the preheat on the basis of a cooling water temperature of the engine (10) so as to execute the engine start after a warming-up of the engine (10) is reliably finished. Further, during the execution of the preheat, a lighting lamp (28) is turned on, and that incidence is recognized to a driver. When the preheat is completed, the ECU (30) automatically starts the engine (10). <IMAGE>
