Abstract
Diesel engines provide a good trade-off between customer requirements of high power, torque, quick response, fuel consumption and pollutant emissions; since they are optimized for this, hence further improvements becomes a hard task. Indian automotive market is govern by cost and when we are talking about off road application diesel engine, then this cost also govern by fuel economy and oil consumption. To makeup this cost all OEM's want solutions in quick time and with minimum expenditure. Design and manufacturing of diesel engines cylinder head is very complex work and if it is for off road application then we need to consider the development cost and time from first day. In-cylinder fluid motion is one of the key factors for controlling the diesel combustion process. Main objective of this work is to design and optimize 5 different inlet port options for a family of engines keeping cylinder head water jackets core common for all variants. Three dimensional CFD simulation approach involving Swirl and flow parameter is used for optimization of cylinder head swirl and flow values. Design and optimization work is carried out on 4 Cylinder 4V engines with swirl options ranging from 0.75 to 1.8 for combustion optimization strategy and are validated on actual cylinder head. © 2018 FISITA.
