摘要：
An exergy model for naturally aspirated compression ignition engines has been validated with experimental data from a four-cylinder 3.92-litre engine testing on a dynamometric test bed. For full load, in two engine operation modes at rated speed and maximum torque speed, the influence of the atmospheric pressure and temperature factors on the main exergy terms was investigated, as well as that of the compression ratio and excess air coefficient. The results indicate the paths to reduce exergy destruction by means of engine design and operation parameters.
