A Thermodynamic System Analysis Model of a Diesel Engine.
Abstract
A thermodynamic system model of a direct injection-type diesel engine has been developed. The objective of the modeling was to enable predictions of the instantaneous temperature distribution along and into the combustion chamber of a diesel engine. The present model has a main emphasis on the heat transfer computation with inclusion of new submodels of conduction, radiation heat transfer of the engine, plus engine energy conversion processes. The development of submodels of space-resolved heat release and species distribution in the global model was not possible during the period of the present contract (01 August, 1984 - 31 July, 1985). Consequently, some assumptions were employed for replacing the said submodels in the selected sample computations based on some of the reported results on heat release and heat transfer rates made available in literature. Some results obtained from the present computational study are included in the report and the usefulness of the new computer program for the actual engine design is suggested herein. In addition, recommendation for improvement of the present computational model is included. Keywords: Pistons; Finite element analysis; Three dimensional heat transfer; HEATRAN computer program; FORTRAN. (Author)
