An Optical Engine Used as a Physical Model for Studies of the Combustion Process Applying a Two-Color Pyrometry Technique

This work describes an experimental installation for the investigation of combustion and injection processes. is based on a two-stroke direct diesel engine with total displacement 3 L cylinder head equipped three quartz windows. The windows are optical accesses that allow studying process injection, atomization evaporation fuel jet in inert atmosphere (nitrogen), reactive (ambient air). Additionally, application two-color pyrometry technique to measure soot formation this facility presented. A methodological study carried out regarding influence dynamic range detectors wavelengths used. Maps KL2C, flame temperature, error probability use cameras high provides better results since system seems be less sensitive measurement noise, fewer points obtained non-physical solution. Moreover, appropriate combination interference filters can improve reliability greater difference between both filters, solution, which improves results.
