Analysis of Energy Utilization of a Diesel Engine

摘要

There are two methods evaluating the energy utilization system: energy balance analysis and exergy analysis. Energy balance analysis is to study the amount of energy conversion, transmission, utilization and losses, and also to determine the energy efficiency of a system or device. Nevertheless, exergy analysis is to judge the quality of different energies, such as high quality energy and low grade energy, to make full use of it and avoid wasting. In this paper, the simulation of working process on a middle-speed diesel engine is performed. With this simulation, the energy utilization is evaluated by the above-mentioned two methods.
