Diesel engines are one of the most important prime movers for mobility and reorganized power generation and are
categorized by heterogeneous combustion. Heterogeneous combustion leads to formation of soot and NOx in the
combustion chamber. The gasoline injection system, which is the heart of an engine, plays a pivotal role in the fuel–air
mixing processes inside the combustion chamber. Fuel atomization activities are mainly contingent on constraints such as
nozzle diameter, injection pressure, ambient conditions, and nozzle geometry. Fuel atomization also depends on fuel
properties such as viscosity, density, surface tension, and vapor pressure. The main objective of our research work is to
design and development of fuel injector holder in high pressure spray chamber, which is used to develop spray formation
and understand the behavior of various fuel spray characteristics like diesel and bio-diesel. An important parameters are
used to find in the characteristics are fuel spray, fuel spray length, fuel regions, droplet size. In our research also
concentrate to arrest the leak formation in high pressure spray chamber.
