Abstract: A system for recycling exhaust heat from an internal combustion engine is based on a recycling type of circulating a working fluid using the exhaust heat from the internal combustion engine. The system may include an EGR line configured to circulate a portion of exhaust gas generated from the internal combustion engine to an intake side, a working fluid circulation line configured to rotate a turbine with a working fluid vaporized by heat transferred from the EGR line, and an EGR side heat exchange unit configured to thermally connect the EGR line to the working fluid circulation line to cool an EGR gas by transferring heat from the EGR gas to the working fluid.

Abstract: A system of recycling exhaust heat from an internal combustion engine may include a working fluid circulating line configured to rotate a turbine with a working fluid vaporized by heat received from an EGR line of the internal combustion engine, an EGR side heat exchanging unit configured to perform a heat exchange between an EGR gas and the working fluid to thereby cool the EGR gas and transfer heat from the EGR gas to the working fluid, and a gas-liquid separator configured to be formed between the EGR side heat exchanging unit and the turbine to thereby supply only a gas component of the working fluid to the turbine.

Abstract: Disclosed is a wing structure of air swirling device for internal combustion engine, which has a swirling device body mounted in an air cleaner, a plurality of wings mounted slantingly and radially on the swirling device body for accelerating or increasing an airflow revolution, and one or more slits formed on prescribed positions of the plurality of wings for suppressing the formation of eddy in a negative pressure zone on the rear surface of each of the plurality of wings, includes a plurality of auxiliary wings protrudedly provided to the outside with reference to the surface of each of the wings, so that the airflow collided against the surface of each of said wings go straight ahead.
