Transient performance anlaysis of combustion engines for alternative automotive fuels:simulation and experimental results

摘要

In this study the heat transfer from the walls of an SI engine cylinders to the cooling medium has been analyzed.Theoretical analysis has been arried out by the simulation program SOM-I.The calculated heat transfer coefficients were compared with the experiental ones different coolign water parameters and for alternative fules i.e. natural gas an dhydrogen.The effect of the alternative fuels on the expergetic effiuciency and the exhaust emissions were also studied and discussed.
