Research on NOx Emission Characteristics of Medium Speed Diesel Engine

Abstract:

In order to research the NOx emission characteristics of the medium speed diesel engine DN8340, a finite element model is built. Calculate the influence of changing the intake charge temperature and injection timing on NOx emission, and forecast how it works to decrease the intake charge temperature and delay injection timing by the methods of Miller-cycle, oscillating cooling piston and electronic controlled high pressure common rail. The calculation result shows that Decreasing the intake charge temperature and delaying the injection timing can reduce the NOx emission to 2.22g/kWh effectively which meets the requirement of IMO TierIII.
