摘要： PROBLEM TO BE SOLVED: To provide an exhaust heat recovery device which can be attached to an exhaust pipe by a simple method.
SOLUTION: The exhaust heat recovery device attached to a pipe 100 through which a heating medium flows, includes an exhaust heat recovery device body 10 having at least two cylinders 22, 32, and a criterion body 42 which serves as the criterion of relative positions of the two cylinders. The exhaust heat recovery device body is attached to the pipe via the criterion body. A Stirling engine may be employed as the exhaust heat recovery device main body. The exhaust heat recovery device can be attached to the pipe by the simple method. Since the criterion body and the pipe can be connected and secured to each other, the accuracy of attachment of the exhaust heat recovery device to the pipe can be prevented from being lowered. Further, since there is provided a heat transfer suppression structure which prevents the heat of the heating medium from being transferred to the outside of the pipe so that the transfer of the heat of the heating medium to the outside of the pipe can be suppressed, the loss of the heat source can be suppressed and the reduction in output of the exhaust heat recovery device can be prevented.

摘要：【課題】ブローバイガスによるエンジンオイルの劣化を防止する。【解決手段】機関1は、電動バキュームポンプ24の排気口に接続される排気口通路27と、クランクケースに新気を供給する新気供給通路21と、新気供給通路21と排気口通路27との連通と非連通とを切り替え可能な流路切り替え機構30を備える。機関1はPCV装置によるブローバイガスの換気量が不足する領域において、流路切り替え機構30を排気口通路27と新気供給通路21とを連通させ、電動バキュームポンプ24を駆動してクランクケース1D内に新気を加圧して供給する。その結果、従って、クランクケース1D内のブローバイガスを圧送された新気で掃気することができる。その結果、クランクケース1D内のブローバイガス濃度は薄くされると共にオイルとの接触機会も減少され、オイルの劣化を大幅に抑制することができる。【選択図】図1
