Abstract

Abstract

Emission control of heavy-duty (HD) diesel engines is one of the focuses to reduce the air pollution. California Air Resources Board (CARB) had taken the action on issuing a white paper to further limit the emission of heavy-duty vehicles, which especially suggested reducing the NO_x emission to maximum 90% based on EPA2010 legislation (0.027 g/(kW·h)). To satisfy the ultra-low emission requirements, global related research institutes carried on a lot of tasks to explore the potential pathway for the future heavy duty after-treatment solutions. To some extent, these actions purged the upgradation of emission legislation around the world, including Europe and China. This paper reviewed the current status of HD diesel engine emission control and available approaches for future emission control obtained from published materials and author's study from the point of aftertreatment component. Thermal management and emission control system should be considered together during the engine design. The paper compared different solutions such as passive NO_x absorber(PNA)/close-coupled SCR(cc-SCR)/SCR on Filter(SCRF) in NO_x control, ash management and PN emission in DPF control, electrical heated catalyst (EHC)/diesel burner in aftertreatment temperature control.
