Abstract
The aim of current study was to compare the global fuel spray
characteristics between renewable hydrotreated vegetable oil (HVO)
and crude oil-based EN 590 diesel fuel. According to previous
studies, the use of HVO enables reductions in carbon monoxide (CO),
total hydrocarbon (THC), nitrogen oxide (NOx) and
particle matter (PM) emissions without any changes to the engine or
its controls. Fuel injection strategies and global fuel spray
characteristics affect on engine combustion and exhaust gas
emissions. Due to different physical properties of two different
fuels, fuel spray characteristics differ.
Fuel spray studies were performed with backlight imaging using a
pressurized test chamber imitating real engine conditions at the
end of compression stroke. However, the measurements were made in
non-evaporative conditions. Various injection parameters such as
injection pressures and orifice diameter were tested. The global
fuel spray characteristics such as spray tip penetration and spray
angle were compared with various injection parameters and two
different fuels. Velocities of spray tip penetrations were measured
by double frame imaging method.
