Research Of Engine Data Acquisition System

On abroad,the combustion analyzer specialized for researching the process of cylinder is more mature and powerful, but it is more expensive and difficult for maintenance, thus it is to develop the relative equipments in demestic.On the basis of imitating the combustion analyzer of abroad, self-developed and worked out a number of engine data acquisition analyzers which suit our conditions .The study of this thesis as follows:Firstly, Design the hardware system which needed by the Acquisition and combustion Analysis of diesel engine Transient cylinder pressure.Secondly,Use the Visual C + + 6.0 and Visual Basic 6.0 tools, with the object-oriented design method, and make use of multi-threaded, multi-buffer, and other technical to compile the cylinder pressure Acquisition and combustion Analysis System.The software can achieve data acquisition, mapping, data archiving ,combustion Analysis and other complex functions.Thirdly,Determine the analysis model of Combustion Heat Release Rate for Diesel Engine to calculate the Combustion Heat Release Rate and draw the corresponding graphics.Using current equipment in laboratory. multi-cylinder, engine signal acquisition and combustion analysis system is developed. Through the real-time monitoring of the cylinder dynamic pressure, develop data acquisition and combustion analysis system, draw the Dynamometer Card , and analysis cylinder combustion conditions which provide valuable information for scientific research...
