Comparative Analysis of Emissions Using Cfd for Two Types of Combustion Chamber Geometryin A Diesel Engine

Lokesh Aurangabadkar, Ibrahim Hussain Shah

Abstract :

The objective of the present investigation is to assess the influence of the combustion chambers geometry on temperature distribution and engine emissions. A computational fluid dynamics (CFD) Code ANSYS FLUENT has been used for modelling the combustion chamber geometry and for its analysis. In particular two different combustion chamber geometries were investigated. To perform this work, a 30o sector of Diesel Engine Combustion chamber is modelled for two different geometries. In first case a 30o sector of Toroidal Combustion Chamber is modelled using ANSYS 14.0. This geometry under observation was analysed, by giving various operating parametric inputs and results were obtained for emission of NO, N2O, CO, CO2 along with the temperature profile. In second case the 30o sector of a Re–Entrant combustion chamber is modelled and same process has been adopted for this geometry. In the end the results for the two geometries are compared.
