Title:
ENGINE EXHAUST DEVICE
Document Type and Number:
Japanese Patent JP2015200196
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an engine exhaust device which can enhance exhaust heat recovery efficiency more than before in an operation state that exhaust flow rate is small while maintaining the exhaust heat recovery efficiency low in an operation state that the exhaust flow rate is large.SOLUTION: An engine exhaust device which introduces exhaust discharged from an engine to the outside comprises a plurality of distribution passages which distribute exhaust discharged from the engine and makes it flow, and exhaust heat recovery machines which are arranged at a plurality of the distribution passages one by one, and recover the heat of the exhaust. The exhaust heat recovery machine comprises a cylindrical exhaust heat recovery part which is arranged in the distribution passage, and recovers the heat of passing exhaust, and a cooling part which cools the exhaust heat recovery part from an external peripheral side via a cooling fluid. A diameter of the exhaust heat recovery part is set larger than an axial length of a shaft of the exhaust heat recovery part.
