Review on BS-VI norms and Particulate Matter emission of diesel engines

The new BS-VI norms which will bring down the NOx, HC & PM values for diesel and petrol engines.For diesel engines will have less no. of NOx, HC + NOx & PM values. The emissions from the engines will be measured in a different way than the traditional method; it will be done by use of a particulate counting machine, which will be counting the particulate matters that are coming out of the exhaust of the engines. Particulate matter consists of 3 major sub-types i.e. soot, insoluble part, and soluble part. For reducing Particulate Matter emission of diesel engines, Diesel Particulate Filter (DPF) is used. In this review paper we are focusing on composition of diesel exhaust gases, Particulate matter types, Need and evolution of BS-VI engine norms, Techniques used for measurement of emission from engines and Diesel Particulate Filter. Future scope involving Real time Driving Emissions is also discussed in this review paper.
