1. Purpose of Research
- Diesel vehicles is being aggressively regulated to reduce NOx emission from the public and regulatory agencies in Korea since 1991.
- Domestically, the number of passenger and light duty commercial diesel vehicles which were registered before EURO 4 regulation account for 45% of the number of all registered diesel vehicles.
- Regulations before EURO 4 allowed over 2~3 times higher NOx emission than regulations after EURO 4.
- Therefore, researches are necessary to reduce NOx emission for diesel vehicles which were registered before EURO 4 regulation. And the research team aims to develop Cooled EGR System to reduce NOx emission for decrepit diesel vehicles.
