Flow analysis of piston head geometry for direct injection spark ignition engine
Abdul Rahim Shar Anuar1, Mohd Farid Muhamad Said2, Nur Adila Mohamad Shafie3, Azhar Abdul Aziz4, Henry Nasution5.
Constructors of gasoline engines face higher and higher requirements as regards to
ecological issues, and increase in engine efficiency at simultaneous decrease in fuel
consumption. Satisfying these requirements is possible by the recognition of the
phenomena occurred inside engine cylinder, the choice of suitable optimal
parameters of fuel injection process, and the determination of geometrical shapes of
the combustion chamber and piston head. The aim of this study is to simulate flow in
Fuel Direct-Injection engine with different geometrical shapes of piston head.
Designing piston head shapes was done by referring to existing motorcycle, Demak
200cc-single cylinder using SolidWork and ANSYS software. The parameter
investigated are shallow and deep bowl design of piston head. In term of fuel
distribution throughout the combustion chamber, engine model that has deeper bowl
(Model 2) shows better fuel distribution than model of shallow bowl as it manages to
direct the fuel injected towards the location of spark plug. Total kinetic energy of
Model 2 is about 20%
