Summary:

With the implementation of BS6 Norms, there is an increased focus on reducing particulate matter emissions from gasoline Direct Injection (GDI) engines. GPFs are effective in capturing particulate matter (PM) and particulate number (PN) but their calibration is critical to ensure optimal performance and emissions compliance.This paper presents a study on the calibration of Gasoline Particulate Filters (GPF) to comply with Bharat Stage-6 (BS6) emissions norms. The focus is on thermal management, soot loading, ash loading, and the unique challenges faced in the Indian market. Thermal management strategies include active and passive methods to optimize GPF regeneration and prevent thermal degradation. Soot load detection involves engine-out simulation-based approach as well as delta-Pressure-based approach for accurate soot modelling. Impact of ash loading and its effects on filtration efficiency and pressure drop will also be discussed.Further the strategies to overcome the challenges with respect to variations in driving conditions, ambient conditions, and the need for cost-effective solutions ensuring effective GPF calibration for Indian market
