Objective
AN ESTIMATED AVERAGE ENERGY SAVING OF 5% IN SPECIFIC FUEL CONSUMPTION COULD ACCRUE FROM THE APPLICATION OF THE PROPOSED "FUEL MANAGEMENT SYSTEM" (FMS) IN DIESEL ENGINES. RESULTS FROM THE SOCIETY'S PHASE 1 PROGRAMME IN THIS AREA INDICATE SPECIFIC FUEL CONSUMPTION VARIATIONS UP TO 12% RELATED TO CHEMICAL DETAILS OF COMMERCIALLY AVAILABLE FUELS.
THE PROPOSED WORK WOULD ALSO PRODUCE A PREDICTIVE CAPABILITY FOR THE ASSESSMENT OF VARIABLE QUALITY FUELS AND WOULD INDICATE PROCEDURES NECESSARY TO IMPROVE SAFETY. THE PROPOSED FMS SYSTEM WILL OPTIMISE PERFORMANCE WITHIN A SET OF RELIABILITY CONSTRAINTS.
IN MODULE 3 OF THE PROJECT, ADVANCED COLLECTION AND ANALYSIS OF GASEOUS AND PARTICULATE CONSTITUENTS WILL BE UNDERTAKEN. TRENDS IN THE RELATIONSHIP BETWEEN FUEL, COMBUSTION AND ENVIRON,MENTAL EFFECTS WILL BE ESTABLISHED.
IT IS EXPECTED THAT A BASIS FOR LONG-TERM RESEARCH IN THE MATHEMATICAL INTERPRETATION OF FUEL RELATED COMBUSTION DETAILS AND FOR THE THEORETICAL EVALUATION OF FUTURE ENERGY RESOURCES WILL BE ESTABLISHED.
A comprehensive diesel engine simulation facility (DEFOS), which could be used to predict the effects of variable fuel quality on engine performance, was developed with the assistance of one of the most comprehensive fuel databases worldwide. During the 3 year project(1986 to 1989) some 40 different fuels were chemically analysed and tested in a number of experimental and production engines.
Chemical analysis was undertaken using nuclear magnetic resonance (NMR) spectroscopy, thermal analysis including thermogravimetry and differential thermal analysis (DTA), elemental analysis and hydrocarbon group analysis by high performance liquid chromatography (HPLC). The purpose was to analyse the influence of structure and composition of fuels on their ignition and combustion behaviour. 5 different engines (Ruston, Ricardo Atlas, Sulzer, MAN B&W, Fincantieri) were utilised in the test programme which was designed to investigate the interaction between engine design features and fuel characteristics.
Depending on the information available on fuel properties, engine type and fuel treatment equipment, DEFOS can be used to provide either qualitative advice or detailed quantitative predictions. For this purpose, a number of new ignition and combustion correlations established from the analysis of the experimental data were used. Furthermore, an existing combustion model has been extended using a revised fuel air combustion product property routine capable of accommodating any average carbon hydrogen ratio. It has been shown that it is possible to predict the full engine power to within 50% accuracy.
THE PROPOSED RESEARCH PROJECT COMPRISES EXTENSIVE EXPERIMENTAL INVESTIGATIONS AND ANALYTICAL WORK PERTAINING TO THE DEVELOPMENT OF A DIESEL ENGINE SIMULATION CODE FOR VARIABLE QUALITY FUELS. MECHANICAL AND THERMAL LOADINGS, WEAR RATES AND DEPOSIT, WILL BE COMPUTED, AND THEIR VARIATION WITH CRITICAL FUEL PROPERTIES WILL BE PROTECTED FOR DIFFERENT ENGINE DESIGNS.
THE ENGINE SIMULATION WILL BE BASED ON ESTABLISHED CODES WHICH WILL BE ENHANCED IN LIGHT OF THE TEST DATA AND NEW MATHEMATICAL MODELS TO BE PRODUCED IN THE PROJECT. IT WILL BE USED FOR THE DESIGN OF A FUEL MANAGEMENT SYSTEM WHICH WILL FACILITATE THE AUTOMATIC CONTROL OF ENGINE OPERATING PARAMETERS TO OPTIMISE PERFORMANCE IN RELATION TO A SET OF FUEL CLASSES. THE FUEL CLASSES ARE BEING DEFINED BY STATISTICAL ANALYSIS OF TEST DATA. DEVELOPMENT INVESTIGATIONS AND TESTS IN THE AREAS OF INJECTION, TURBOCHARGER AND CHARGE AIR TEMPERATURE WILL BE UNDERTAKEN TO ESTABLISH THE PRACTICAL CONSTRAINTS IN THE APPLICATION OF CONTROL SYSTEMS IN THESE AREAS. THESE DEVELOPMENT TESTS WILL ALSO VALIDATE THE OPTIMIZATION PROCEDURES.
