Abstract
Diesel engines are used in automotive and stationary
applications. The main problem with diesel engines is emissions
of nitrogen oxides (NOx) and particulates. In order to minimize
the emissions, it is necessary to design the diesel engine with
better in-cylinder flow (air-fuel mixing) and combustion
process. Computational Fluid Dynamics (CFD) simulation
helps to understand the Diesel engine temperature distribution
and NOx species concentrations with respect to time. A small
direct injection (DI) engine was chosen for the study. CFD
simulation results were compared with that of engine emission
tests. Results were found to be in agreement with NOx
emissions. This paper also presents the simulation results of
direct injection diesel engine in-cylinder flow (air-fuel mixing)
and combustion.
