/ 159 With the help of optical measuring methods, a detailed insight into the complex processes of fuel mixture and combustion beyond the findings of the pressure indicating method can be achieved. AVL Visiolution technology helps users understand the whole process in detail and, therefore, provides the right tool for improving performance in terms of fuel consumption, mixture formation, exhaust emission and engine power. The system is based on indexing in the combustion chamber. AVL Visiolution technology provides the perfect tool for flame evaluation, thermal radiation and injection monitoring, making complex processes clearer. The formation of pollutant emission in transient operation becomes understandable. Engineering duties are finished in record time and with utmost precision. MEASURING PRINCIPLE Visioknock/VisioFlame/VisioTomo: Special spark plugs or head gaskets equipped with glass fibers allow optical access to the combustion chamber. This allows observation of flame propagation, localisation of knocking sounds and access to combustion patterns. VisioFEM: cycle-precise, cylinder-specific recording of phenomena that contribute significantly to pollutant emissions VisioScope: carburetion, fuel injection, soot formation and temperature distribution are recorded by endoscope and camera BENEFITS AT A GLANCE • Measurement in highly transient operation • Best suited for exploring injection strategies • Finding critical emission cycles • Engineering mixture formation • Evaluation of flame propagation • Evaluation of thermal risk • Detect potential for knock limit improvement • Detection of root causes of irregular combustion • Cold start/tip-in/tip-out emission evaluation • Services covering the whole Visiolution range • Perfect interface to existing AVL indicating chain AVL Visiolution Systems Optical Access to the Engine
