| Abstract: | The exhaust emission experiment is taken for an automotive EFI gasoline engine under 9 mode emission test cycle.Based on the calculated contributions of the single mode and same kind of test modes,each test mode emission contributions of three kinds of pollutants(CO,HCand NOx)are analyzed,the degree of the effect of the engine emission experiment results in each mode is obtained,and the key modes of this kind of gasoline engine to improve the emissions level is presented. |
