Indicator Diagram Simulation And Burning Analysis System Of Internal Combustion Engine Based On LabVIEW

There should be deeply analysis on burning process and emission statement of the internal combustion engin in order to decrese the fuel consumption and the emision,also improve the thermal efficiency.Additionally,emmision prediction is also essecial in designing and improving the performance of a internal combustion engin,which can greatly saving money and time.From these points,we know that burning analysis,emision analysis and prediction are there main elements in the burning and emmision analysis system for internal combustion engin.Indicator diagram is the basis for researching and diagraming the working statement,heat release rate analysis, and emission prediction. So,indicator diagram must be included in the burning and emmision analysis system.Additionally,indicator diagram can also be used for basic performance character calculation,dynamic and intense analysis,and assessing the burning process.Generally,there are two methods to obtain the indicator diagram.One is by experiment,the other is by numerical simulation.Above on,burning and emmision analysis system for internal combustion engine includes indicator diagram acquisition,emission analysis and emission prediction.This dissertation has developed some part of the burning and emmision analysis system,includes "pressure handling and burning analysis subsystem "and"indicator diagram simulation for diesel".Main works as follows:1. Programming the simulation and analysis software includes data playback,data process,burning analysis and indicator diagram simulation in use of Lab VIEW.2. Software test. Test every function of the system using the referent data from 6135ZG.3. Burning analysis on 6135ZG4. Comparatively analyse the working statement of the engine when it works within the load characteristics curve.From this dissertation,we know that it is feasible to establish the burning and emmision analysis system for internal combustion engine using visual instrument technology,which makes the system more flexible,lower cost and circle time.
