EXHAUST HEAT RECOVERY SYSTEM FOR ENGINE

PROBLEM TO BE SOLVED: To improve startability of an engine at a low temperature. SOLUTION: Since the startability of the engine 2 is reduced at the low temperature, a pump 10 is beforehand operated to circulate a heating medium, when an engine temperature detected by a sensor TS3 is lower than a bas...

Zusammenfassung:	PROBLEM TO BE SOLVED: To improve startability of an engine at a low temperature. SOLUTION: Since the startability of the engine 2 is reduced at the low temperature, a pump 10 is beforehand operated to circulate a heating medium, when an engine temperature detected by a sensor TS3 is lower than a base temperature. Since heat of hot water in a hot water reserving tank 17 is transmitted to the engine 2 by the heating medium, the engine is warmed, viscosity of oil is reduced, dew condensation formed in the engine 2 is prevented, and thereby, the startability is improved.
