Overview: In light of the increasingly stringent emission standards for heavy-duty on-highway diesel engines, this paper highlights the role of insulation in maintaining high exhaust temperatures and ensuring that emission reduction targets are met. It presents a brief history of the on-highway emission standards and details the industry's response to the emission control standards for diesel engines with reference to engine modification and after treatment strategies. The importance of proper insulation of the exhaust, catalysts and SCR systems to maintain high internal temperature and ensure optimal performance and burn-off of the exhaust gases is detailed. The paper concludes by stating that insulation will continue to play a significant role in the various emission reduction solutions.
