ASM2525 검사모드 중 시료채취관 이탈 확인방법 연구

The current fleet of more than 14.6 million vehicles driving on Korean highways is one of the most important source of air pollution. Much of emission deteriorations and malfunctions would be found after emission warranty of vehicle manufacturers. If these malfunctions could not be properly maintained, these vehicles will not perform as originally designed, causing them to work harder, wear out faster, and pollute more. Specific improvement plan for Korean inspection and maintenance (I/M) program is described in this study. Some recommendation for check method against improper sampling probe installation for ASM2525 test mode is recommended. Lambda and CO+CO₂value is strongly correlated to the amount of dilution air. Based on this review, the improvement plan for Korean ASM 2525 test for gasoline and gas fueled vehicle could be established.
