Experimental Analysis on Exhaust Gas Temperature of Various Four Cycle Gasoline Engines 790308

This paper discusses the relation between the exhaust gas temperature and the engine parameters.
The engine speed, load, spark timing, air fuel ratio and exhaust gas recirculation ratio were chosen for the calibration parameters, and the compression ratio, valve overlap timing, engine displacement, the number of cylinders and others were chosen for the design parameters. A series of tests were done on six different engines. The data were analyzed statistically and the experimental equation was derived with which the exhaust gas temperature can be estimated.
The paper includes the process of the analysis and some application of it.
