Abstract
A problem to be solved is to provide an exhaust promotion method, an exhaust promotion device, and an exhaust system improvement method for an internal combustion engine capable of further improving the exhaust efficiency by high-speed exhaust of exhaust gas. What is characteristic is that an exhaust gas discharged from the internal combustion engine is expanded in multiple stages repeatedly to reduce a temperature thereof, and thus exhaustion is performed while suppressing a behavior derived from a thermal energy of the exhaust gas.
