EXHAUST HEAT RECOVERY DEVICE OF ENGINE

PROBLEM TO BE SOLVED: To provide an exhaust heat recovery device of an engine so formed that a condensed water produced in an exhaust gas heat exchanger is hardly frozen at a small diameter portion in an exhaust gas route when the engine is operated to stop in a short period of time. SOLUTION: The e...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an exhaust heat recovery device of an engine so formed that a condensed water produced in an exhaust gas heat exchanger is hardly frozen at a small diameter portion in an exhaust gas route when the engine is operated to stop in a short period of time. SOLUTION: The exhaust gas route is set to feed the exhaust gas of the engine from the exhaust gas heat exchanger 9 to a plurality of mufflers 23, 25, and 27 positioned above the exhaust gas route. The exhaust gas outlets 236 and 255 of the intermediate mufflers 23 and 25 are open to chambers 235 and 254 on the upper part of the inner bottom parts of the chambers 235 and 254. Since the chambers 235 and 254 are used as reserving chambers for the condensed water when the engine is stopped, the accumulation of the condensed water near the outlets 236 and 255 on the upper side of the reserving chambers can be suppressed. Exhaust gas hoses 21, 24, and 26 are laid out so that a horizontal part is absent for preventing the condensed water from being accumulated. COPYRIGHT: (C)2006,JPO&NCIPI
