| Zusammenfassung: | From the beginning of IC engine era, it is trying to improve the performance and
efficiency of internal combustion engine. In this study, numerically analysis on
combustion of Propane, Propanol and Octane in SI engine have been done
thoroughly and presented to assess the potentiality and highlighted the
comparison. For this analysis thermodynamic engine cycle model is developed
for numerical analysis. Mathematical models considering fundamental equation
and empirical relation are implemented in a single cylinder 4 stroke spark
ignition engine (system) with the help of FORTRAN 95 to find out heat losses,
friction losses, output parameter etc. Single cylinder four-stroke spark-ignition
(SI) engine is considered as system. In this study, different working parameters
like 8 and 12 compression ratios with three different rpm 2000, 4000 & 6000
are considered for simulation. This study shows the different comparisons of
energy-exergy content (%), as example of exhaust gas 35.08 & 17.82, 37.02 &
19.22, 37.79 & 19.79 for Octane (at compression ratio 8 and 2000, 4000, 6000
rpm) etc., which explains the potentiality content and the potentiality losses in
different process like combustion, mixing of gases etc. It also shows for the fuel
propane and propanol in similar way with changing different operating
conditions. Maximum inside cylinder temperature, 1st law and 2nd law
efficiencies were determined for the fuels with respect to different compression
ratio and engine speed. |
