| Abstract: | The paper describes the developed monitoring system which can be used in detecting,monitoring and diagnosing of diesel engines.To eliminate the error of passage effect,a digital filtering method for processing indicator diagrams of I.C.engines,which is based on the theory of digital processing,is investigated.On the basis of analyzing combustion characteristic of diesel engines,the paper also gives out a method to correct the error of TDC in cylinder pressure measurrements. |
