Title:
INTERNAL COMBUSTION ENGINE EXHAUST PROMOTION METHOD, EXHAUST PROMOTION DEVICE, AND EXHAUST SYSTEM IMPROVEMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2021/255973
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing an internal combustion engine exhaust promotion method, exhaust promotion device, and exhaust system improvement method capable of further improving the exhausting efficiency that results from exhaust gas being exhausted at high speed. The present invention is characterized in that exhaust gas discharged from an internal combustion engine is repeatedly expanded in multiple stages to lower the temperature thereof, thereby exhausting the exhaust gas while suppressing behavior attributable to the thermal energy of the exhaust gas.
