Retrofitment Programme • In US densely populated cities in NE, emission from diesel vehicles accounted for 33% of all NOx and 80% of PM emissions. • Retrofit programme help in bridging the time gap until the new low emission vehicle models are able to penetrate the existing fleet. • Prerequisite conditions for retrofitment programme are‐engine condition; vehicle integration; low sulfur fuel and maintenance regime for in use vehicle fleet. • During the last decade number of countries have successfully implemented the retrofitment programmes. • These countries include ; USA (About 160,000 diesel vehicles); UK(14000 vehicles); France (5000 vehicles);Switzerland(10,000 Vehicles);Sweden (4000 truckes);Hongkong(50,000 catalysts);South korea(500000Vehicles) etc.
Retrofitmnet options • DPFs: (Diesel Particulate Filters) Reduce particulate matter from exhaust by mechanical filtering. It also reduces the size of particles in a uniform manner i.e. both small and large particles are reduced. For regeneration catalyst are coated on the surface of the filter which reduces ignition temperature to oxidise accumulated particulate matter. • DOCs: (Diesel Oxidation Catlyst) Oxidises CO and HC and liquid hydro‐carbon adsorbed on carbon particles called soluble organic fractions (SOFs) • SCRs: (Selective Catalytic Reduction) converts NOx into N2 and O2. Reduction in nOX is around 75‐90%. HC and PM also get reduced.It also reduces the odour produced by diesel engine and diesel smoke. In mobile source we normally use aqueous urea solution i.e. AdBlue. It is a amonia based reducing agent injected in the exhaust in downstream
