[연소부문] EMISSION 법규 강화에 따른 배출가스 측정 기술에 대한 연구

The interest on the air pollution is gradually rising up over the world and emission regulations get more stringent. All automotive industries have been working on the exhaust emission reduction from vehicles through a lot of approaches and researching equipments and methods precisely to evaluate exhaust emission levels of cars which is correspond to that stringent regulations. So in this paper, we focused on the side of equipment and valuating method to exclude the influence of ambient air contamination and water condensation. We discussed the effect of Air Purifier, the type of volume sampler and the heated pipeline in the equipment aspect and evaluated the difference between the regular OF(Dilution Factor) and the modified Of to suggest an appropriate combination of measuring equipment and method.
