Abstract: Based on the study of the mechanism of automotive thermal reactor and the experimental study on the exhaust temperature characteristic of automotive gasoline engine,the varying scopes of exhaust temperature of gasoline engine under diverse typical running operations are explored. And the purification effect of thermal reactor is discussed on the engine rig tests under several essential characteristic operations as well.

Key words: Exhaust temperature, Gasoline engine, Secondary air, Thermal reactor
