Energy balance analysis of diesel engine

In this paper, the energy balance analysis of diesel engine system is introduced, and a medium-speed diesel engine was used as a research object to build simulation models. The correctness of model was verified by comparing simulation data to experimental result. The energy balance on thermodynamic cycle is analyzed by combining the results of simulation data and theoretical analysis to evaluate the energy efficiency of this diesel engine. Factors of energy efficiency are pointed out by theoretical analysis, and the result of the research on effects caused by changes of parameters is been used to pointing out the path of improving the energy efficiency of diesel engines.
