India is moving to Bharat Stage VI (BS-VI) from 2019 significantly lowering particulate mass (PM) , particle number (PN) and Nitrogen Oxides NOx emissions limits, as well as Carbon Dioxide CO2. BSVI’s particulate limits will require the use of diesel particulate filters (DPFs), which will need to operate properly under the driving conditions prevalent in India. Furthermore, NOx and CO2 emissions control will include advanced combustion modes with advanced fuel injectiontechnologies based on high pressure fuel injection and smaller injector holes, in combination with active NOx reduction measures. These advanced technologies will increase sensitivity to fuel quality, so will require tighter control of sulfur content, water contamination, fuel stability, lubricity and corrosion. These are real challenges for the robustness and durability of strategies developed for BS-VI and beyond.
