Effect of mean piston speed and residual gas fraction on performance of a four-stroke irreversible Otto cycle engine

Year 2018, Volume: 1 Issue: 1, 6 - 12, 30.09.2018

Abstract

In this study, a four-stroke irreversible Otto
cycle model was constructed using the finite time thermodynamics to investigate
the effect of the mean piston speed and the residual gas fraction on the cycle
(or engine) performance. Fuel consumption was taken as a function of mean
piston speed, and initial cycle temperature was considered as a function of
residual gas fraction. It has been assumed that the specific heat does not
change depending on the temperature. A detailed numerical example study has
been made to see the effect of the mean piston speed and the residual gas
fraction on engine performance. As a result of the numerical example made, the
cycle thermal efficiency and the dimensionless power output were observed with
the increase of the residual gas amount and the mean piston speed. We think
that the results obtained are especially important for engine designers.
