Diesel Engine Performance in Vector Space as an Actual Evaluating System
Rapport, 1983

A combination of the measured data from the engine with a mathematical model in terms of the homogeneous deformation theory, leads to appropriate information concerning the running condition of the diesel engine, diagnosis of abnormal conditions and recommendation of appropriate maintenance The most reliable data on physical processes and actual conditions of a diesel engine are generally obtained from a monitoring system. Such a system usually gives information about thermal overload, wearing of different parts of the engine, cylinder pressure, fuel pump performance and operating time of injectors. As a complement to monitoring, an investigation of the air gas path system conditions in terms of the deposits in the air filter, air cooler, compressor, turbine, exhaust piping and exhaust boiler is of great interest. A change in any of these deposits is reflected as a change in the thermodynamic properties of the gas flow throughout the whole system of the turbocharged engine. In order to investigate such parameters, the black box method is applied and the engine performance is reflected in vector space.
