Özet:

 


The hydrous ethanol combined with the
turbocharged engine with exhaust gas recirculation (EGR) has been investigated
with a phenomenological simulation model. This paper analyzes the influence of
the low pressure and high pressure cooled EGR, the intercooler and the amount
of recirculated gases, as they affect the performance parameters in a spark-ignited
ethanol-fueled engine. Using a phenomenological model developed in Matlab®, the
behavior of the pressure and temperature curves is analyzed considering the
variation of the crank angle, the formation of NOx, and the tendency for
knocking. The fuel analyzed is hydrous ethanol (E95h - 5%water by volume),
which is widely used in Brazil. The
proposed technique showed an increased power using the intercooler (IC) while
avoiding knocking. This study showed that the use of a cooled EGR and turbocharged
SI results in increased power, while also
reducing NOx formation, and preventing or reducing engine knocking. In some engines, the low pressure cooled EGR is better
than high pressure, but this can be different for another engine. The model helps to find the best or more adequately equipped for each model
of engine.
