“…6 (e)). Nauwerck et al [2000] used endoscopy to investigate the in-cylinder flow structures during the gas exchange process inside a small two-stroke engine. They successfully implemented this system for PIV under a variety of engine operating conditions and speeds upto 6000 rpm, which is certainly not possible in an optical engine.…”

Due to increasing number of alternative fuels and strict emission norms globally, extensive experimental investigations are being conducted for understanding and improving fuel sprays and combustion of internal combustion (IC) engines. Main objective of this study is to assess the effect of advanced fuel injection equipment (FIE) and in-cylinder processes to improve efficiency and reduce pollutant emissions, in addition to improved understanding of combustion and pollutant formation mechanisms. In order to gain understanding of actual combustion processes and spray characteristics in production grade engines, researchers have developed various optical diagnostic techniques. Endoscopic optical visualization technique is a very effective and relatively cheaper but very challenging technique with great potential amongst them. This paper presents a summary of evolution of endoscopic optical visualization technique for analyzing spray and combustion characteristics in IC engines, current trends in engine endoscopy and some application case studies. This endoscopic technique has great scope in research and development activities for automotive industry.

“…The velocimetry techniques are used mainly to analyse flow of gases en the thermal engine. Some of the most recent applications for this technique can be found in the literature (Choi & Guezennec, 1999), (Kakuhou et al, 1999), (Nauwerck et al, 2000), (Neussert et al, 1995), and (Trigui et al, 1994), where the main application is focussed to the study of mixture formation inside the combustion chamber of a thermal engine, furthermore it considered to be one of the best techniques for this kind of analysis.…”

“…This is mainly due to the variability in access points for the probes. Various setup parameters for endoscopic PIV are described in a pipeline with bends or flow conditioners [4][5][6], internal combustion engines [7][8][9][10][11], rotorstator systems and swirling air [12] and low pressure turbine rig and turbomachinery [13,14]. In all of the mentioned cases it is clear that endoscopic PIV is approached using a two-probe method, that is one for the light sheet optics and another for the imaging optics.…”

Particle image velocimetry (PIV) is a successful flow mapping technique which can optically quantify large portions of a flow regime. This enables the method to be completely non-intrusive. The ability to be non-intrusive to any flow has allowed PIV to be used in a large range of industrial sectors for many applications. However, a fundamental disadvantage of the conventional PIV technique is that it cannot easily be used with flows which have no or limited optical access. Flows which have limited optical access for PIV measurement have been addressed using endoscopic PIV techniques. This system uses two separate probes which relay a light sheet and imaging optics to a planar position within the desired flow regime. This system is effective in medical and engineering applications. The present study has been involved in the development of a new endoscopic PIV system which integrates the illumination and imaging optics into one rigid probe. This paper focuses on the validation of the images taken from the novel single stem endoscopic PIV system. The probe is used within atomized spray flow and is compared with conventional PIV measurement and also pitot-static data. The endoscopic PIV system provides images which create localized velocity maps that are comparable with the global measurement of the conventional PIV system. The velocity information for both systems clearly show similar results for the spray characterization and are also validated using the pitot-static data.
