The present study investigates the challenges on performing the on-road regeneration process in Indian road conditions for meeting BS6 emission. There are different types (DPF and SCR) of aftertreatment systems used for meeting BS6 emission. In which, active regeneration (on-road demand) is used to burn the particulate matter accumulated in the diesel particulate filter (DPF). This process must be performed frequently in order to prevent DPF system from over soot loading which leads to damage the DPF. This process is dependent on exhaust temperature, flow of exhaust and availability of oxygen etc. As we know, Indian roads are different from other countries such as European countries. The abnormal soot loading and frequent regeneration lead to many concerns such as oil dilution, performance of the engine and life of DPF system etc. In this work, different road conditions are categorized as city cycle, mixed cycle and highway cycle driving conditions for analyzing the active regeneration process. These cycles are defined based on the average vehicle speed (city = 25 kmph, highway = 50 kmph and mixed = 25 to 50 kmph). The vehicle was run in different cycles. The variation in the on-road regeneration was captured in all the cycles. This paper shows the variation of fuel quantity, exhaust flow, exhaust temperature and lambda variation in all the cycles. The difference in the regeneration frequency is analyzed in the three different cycles. The regenerations which are interrupted due to vehicle stop or idle stop are also studied to show the effect on the DPF regeneration.
