- Abstract
- A combination of experimental and numerical methodologies is proposed for the investigation of knocking in
spark ignition engines to aid in better understanding the physical and chemical processes that occur and to exploit the
capabilities of a developed computational tool. The latter consists of a thermo-fluid dynamics model, which is part of an
advanced 1-D fluid dynamics code for the simulation of the entire engine, and a complex chemistry model, which can be
embedded into the thermo-fluid dynamics model using the same integration algorithm for the conservation equations and the
reacting species. Their mutual interaction in the energy balance will be considered. The experimental activity was carried out
in the combustion chamber of an optically accessible, single-cylinder P.F.I. engine equipped with a commercial head. The
experimental data consisted of optical measurements correlated to the combustion and auto-ignition processes within the
cylinder. The optical measurements were based on 2-D digital imaging, UV visible natural emission spectroscopy and the
chemiluminescence of radical species (OH and HCO). The engine parameters, the pressure signals of the related data and
optical acquisition are compared on an individual cycle basis in the simulation by running the engine at a constant speed and
varying the spark advance from normal combustion to heavy knock conditions. (literal)
