作動ガス循環型エンジン
Document Type and Number:
Japanese Patent JP5621760
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve the cooling capability of a condensation means for utilizing a heat medium used for cooling an engine body, in a working gas circulation type engine.SOLUTION: In the working gas circulation type engine including the condensation means for utilizing the heat medium used for cooling the engine body, a bypass for supplying the heat medium before cooling the engine body to the condensation means is provided to improve the cooling capability of the condensation means, and combustion product steam contained in a burned gas is separated and removed more efficiency. When a second condensation means is located at the downstream side in a circulation passage of the burned gas, the combustion product steam in the burned gas flowing into the second condensation means is sufficiently separated and removed, and thereby the workload in the second condensation is suppressed and fuel consumption of equipment (e.g., a vehicle) mounting the engine can be improved.
