The Study Of Intelligent Temperature Measure Diagnose System For Ordinary Failure Of Diesel Engine

From the structure and the law of diesel engine,it gives the influnces of the main parts of disel engine to the working state of disel enging,such as the air supply system,the disel oil supply system and the combustion system. So it put forword a diagnose method for diesel enging through temperature measure,just like the diagnose for a man. Compare to other diagnose methods,it is fasten more convenient cheaper and accurate.It gives the hardware and softeware design of the temperature measure diagnose system of diesel enging ordinary failure. The hardware includes a infrared temperature measure appratus which contains memory and communication unites -,a data analysis computer which is used to analysis the data from the temperature measure appratus and gives the result report. The software includes modules such as comunicatio data analysis result print and operation interface between man and computer.it uses BASIC computer language which is easy to the users,the data communication instead of the data input with hand avoids the disadvantage of man and the erro of man.It supplies a great deal of experimental data and the analysis of these data,the result reveals the efficient of this diagnose method,it can be forecast that with the extend of this method there will be much more profit comes from it. (l)It is very important for the state repair of diesel enging in our country;(2) It will help with the more accurate decicision of repair cycle of the engine;(3) It will improve the combustion state of the diesel enging and will keep the oil comsume at a lower level,at the same time,It lessens the dilute of the lubricanting oill in the engine.There are still some more research work to do,for it is just the begining. The mathematic model should be made and more accurate data rule should be established.
