Diesel vehicle provides higher thermal efficiency and less CO 2 emission but there are some more problems such as PM and NO x emission. PM has been decreased to around 90% by applying current diesel particulate filter technology to diesel vehicles. However, in order to meet Euro-6 emission regulation NOx must be reduced to a certain level of emissions. NO x reduction technology such as LNT, LNC and SCR has been developed and applied to especially to heavy duty diesel vehicles and passenger
