Light Duty Diesel Exhaust Gas After Treatment Challenges and Technologies for Post BS-IV Regulations 2013-26-0051
With the implementation of Emissions Stage 5 in Europe all passenger cars with diesel engines need after treatment systems with Diesel Particulate Filters (DPF). Therefore Indian post BS-IV regulations are expectedto force the introduction of DPFs for the Indian domestic market as well. In this paper a new low porosity Aluminum Titanate (AT) DPF generation is discussed and how this new product family can help address specific requirements for the Indian market. Two new technologies of the DuraTrap®AT DPFs complement the existing portfolio. One technology has an increased soot mass limit, the second new product significantly reduces the pressure drop over the filter.
