| Abstract: | In order to decrease NOx emission for an automotive gasoline engine by means of exhaust gas recirculation(EGR),the EGR rate characteristic was optimized experimentally on a dynamometer test bed. Two kinds of pressure controlled EGR systems were developed and their compostions and functions were described. The EGR rate characteristics of the systems were measured. Emission test results of the engine with developed EGR systems were obtained and compared. |
| Keywords: | gasoline engine EGR emission |
