- Summary:
- The Diesel Particulate NOx Reduction (DPNR) system is used for simultaneous reduction of PM and NOx in diesel engine. DPF is used to trap particulate matter in diesel engines. NOx absorber technology removes NOx in a lean (id est oxygen rich) exhaust environment for both diesel and gasoline lean-burn GDI engines. The NOx storage and reduction catalyst is uniformly coated on the wall surface and in the fine pores of a highly porous filter substrate. Combination of these two components in the DPNR results in a compact size of the system. The base diesel engine model validated with pressure crank angle diagram and performance parameters such as Indicated mean effective pressure. This base engine's exhaust emission is given as an input to the DPNR system. The surface reaction is connected to the DPF through chemcon template. The surface reaction is NOx storage and reduction chemical kinetics like Lean NOx Trap. The modelling of DPNR and Base engine is done using GT-SUITE. This paper describes about the 1D simulation of DPNR system with base diesel engine model and the percentage reduction of PM and NOx from the base model
