Experimental study of filtration behavior of diesel particulate filter in a diesel engine to meet BS-VI emission norms in INDIA

Abstract

Due to upcoming Bharat Stage-VI emission norms, emission control has to become mandatory for every vehicle in India. Bharat Stage-VI are the stringent emission norms to be introduced by the Indian government for controlling the vehicle exhaust emissions. Diesel powered vehicles are more popular because of its high thermal efficiency, lower fuel consumption, and lower CO2 emission compared to the petrol engine. Although, diesel-powered vehicles produce more oxides of nitrogen and particulate matter. Diesel particulate filter (DPF) is the new technology to abate the particulate matter. In this paper, a DPF was installed into the exhaust of a single cylinder direct injection diesel engine. In order to investigate the filtration efficiency of DPF and its effect on fuel economy, indicated power and emission characteristics, experiments were conducted on a single cylinder diesel engine test rig. Results showed that after installing the DPF on the engine exhaust there was more than 90% reduction in particulate matter, while specific fuel consumption was increased by about 4% and indicated power was decreased by approximate 2KW.
