Abstract
Performance of compression ignition engine is known to be spray characteristics related. Precise
experimental information on fuel sprays is of utmost importance to model the fuel spray formation
and its development in the engine combustion chamber. The previous experimental work of the
present author on non-evaporating sprays produced by using a FIAT single-hole orifice type
nozzle and a distribution type commercial fuel injection pump forms the basis to derive
correlations for penetration rates, break up times and lengths of diesel sprays. The results are
compared with the existing published work and the agreement is found ideal. The correlations
derived can be useful to do CFD modeling of sprays under variable conditions of injector nozzle
hole diameter, fuel injection pressure, combustion chamber pressure and temperature or air
density.
