AVL Visiolution SoftwareTest environment integrationIntegration platformEfficient use of development tools requires wellintegrated measurement systems and devices.IndiCom offers seamless integration into any testbed environment.In addition to engine calibration work at the testbed, measurements and ECU calibration are alsodone in vehicles to verify the test bed results andto optimize the vehicle, especially in relation to itsemissions and drivability. Getting the completepicture of all measured values in the vehiclerequires an integration platform which can collectand evaluate data from various sources and whichis compatible with the data acquired at the testbed. IndiCom has access to combustion and ECUinformation, fast time based data, drivability values,the vehicle’s CAN bus and the interface to theETAS calibration tool INCA so it is ideally suited tostudy the effects of driver inputs on internal combustion and thus the vehicle’s responses.IndiCom is also a key system for automated ECUoptimization when used in conjunction with AVLCAMEOTM. It additionally provides interfaces toCAN devices, time based acquisition cards, ECUdata and the unique drivability assessment toolAVL DRIVETM. The combination of these toolsmakes the correlation between combustion and itsvarious quality criteria clearly visible.Automatic data synchronization, powerful calculation possibilities, graphical analysis and compatibility with AVL CONCERTOTM post processingmake IndiCom the ideal solution for all in-vehiclemeasurements.Top: Test bed integrationBottom from left to right: INCA OHI interface / in-vehicle testing / IndiCom parameter editor (IndiPar)AVL optical combustion analysis at thetest cell and on boardIndicating tools for analyzing the combustion process have been used for more than 100 years. Butdue to the engine’s increasing complexity, pressure indicating alone is no longer sufficient; this iswhy optical analysis tools are applied. For manyapplications such as the visualization of mixturepreparation, flame kernel monitoring, flame propagation or knock localization, AVL Visiolution Softwareis a perfect extension to pressure indicating toimprove combustion stability, knock probability orthe engine’s exhaust pollution. Its features includedata acquisition, the documentation of referenceconditions and the calibration of light transmission.Furthermore, many comprehensive algorithms forevaluation are provided. Mixture formation leaves a footprint in combustion: measurement of cylinder pressure, flameradiation and flame propagation provides fastinformation about emission and soot formation Knocking – ignition border line: optical sparkplug sensors showing the formation of the flamekernel and knock distribution improve the engine’s efficiency when developing knock Endoscope based technology: easy access forvisualizing processes such as injection or combustion Optical flame temperature measurement: mostlynonintrusive and without delay, inside combustion chamber or exhaust systemEfficient and robust Combustion optimization in transient operation:optical onboard technique supports calibrationwith cycle-based and cylinder-based emissionformation dataTop: Optical spark plug sensorBotton from left to right: VisioFlame, evaluation of flame propagation / diesel flame / VisioKnock, irregular combustion
AVL GCA – Gas Exchange & Combustion AnalysisSupport by Understanding the whole engine processProductivity through traceabilityWorldwide customersMaximum productivity in engine testing requiresefficient management of resources and confidencein the accuracy of the measured data.Acting globally requires global communication anddata exchange. IndiCom is ideally suited for locallyand globally operating companies. It enables theexchange of result data, reports and calculation formulas with the support of an integrated unit conversion tool, a free iFile viewer, and compatibility withthe powerful post processing tool AVL CONCERTOTM.One-dimensional thermodynamic calculation playsa central role in the development process of moderncombustion engines. With its proven and robustsimulation software BOOST, AVL offers a sophisticated tool for the one-dimensional simulation of theentire engine. GCA is based on BOOST and exploitsin great detail parts of this simulation in combination with measurement values. Since both tools usethe same calculation model the consistency of theirresult data is guaranteed. The software option GCAGas Exchange & Combustion Analysis, fully embedded into IndiCom, is used for the detailed calculation and analysis of the whole cycle, the entire gasexchange and combustion process. When calibrating an engine the calibration process becomesmore and more complex, therefore additional andreliable information is needed. GCA provides know ledge of the thermodynamic process directly at thetest bed and delivers additional results that cannotbe measured.Standard input, high information outputFor its analysis, GCA uses measured intake, exhaustand cylinder pressure curves and engine specificTop: Pressures and flowsBottom: Residual gas content due to valve overlappingvalues such as valve lift curves, flow coefficientsand fuel parameters. The results include the rateof heat release, energy and heat balance, wall heatlosses, mass flows, and residual gas content in thecylinder and gas exchange efficiency considering gasdynamic effects.Calculation in dynamic operationThe investigation of the engine’s behavior in dynamicoperation is essential to reducing pollutant emissions.Especially for the engine cold start, high injectionrates are needed, which can cause misfire and entailhigh pollutant emission levels. Therefore GCA provides a cycle-to-cycle analysis for engine calibrationin transient operation.GCA - the virtual sensor Provides information about the whole combustionprocess based on data that cannot be measured– even in transient operation Helps identify the potential for increased power orreduced fuel consumption Checks plausibility to confirm the accuracy of thecombustion measurementAVL’s SensorDataManagement SDM with patented automated sensor detection, sensor runtimetracking and a calibration database ensures thecorrect setup of the measurement chain withreduced parameterization effort.The sensor database is a central digital repositoryfor the administration of sensor specific data. Itcan be either a local or a network database. Foreach sensor all calibration data are stored, the totalnumber of performed cycles or sensor runtime ismonitored and service or calibration intervals canbe scheduled according to the user’s testing needs.Quality assurance standards are supported by thetraceable documentation of the complete measurement chain, which is stored in the measurementfiles (iFile format).
