Özet
In this study, experiments have been carried out with the use of gasoline, liquified petroleum gas (LPG), and biogas fuels in different volumetric percentages in a single cylinder, four strokes, spark ignition (SI) engine with different throttle position. In experiments, data were compared which were obtained by using gasoline, biogas and LPG; brake thermal efficiency (BTE), cylinder pressures, mean gas temperature (MGT), brake specific fuel consumption (BSFC), carbon dioxide (CO2), carbon monoxide (CO), hydrocarbon (HC) and nitrogen oxide (NOx) emissions. According to the results, with the use of biogas and LPG in the full throttle opening (FTO), a 75.52% and 34.19% increase in the BSFC was determined compared to the use of gasoline, while a 16.04% and 8.95% reduction in the BTE was determined. On the other hand, with the use of biogas and LPG, a decrease of 15% and 62.03% in CO emissions, 23% and 63% decrease in HC emissions, 6.77% and 56.42% decrease in CO2 emissions were detected compared to gasoline. In the half throttle opening (HTO), BSFC increased by 85.2% and 45.51%, while BTE decreased by 33.43% and 20.22%. In addition, a decrease of 15.97% and 47.65% on CO emissions, 21.19% and 62.38% HC emissions, 6.84% and 69.54% CO2 emissions were detected. In terms of cylinder pressure value, with biogas and LPG, cylinder pressures decreased about 17.76% and 24.41%, respectively. On the other hand, compared to the gasoline, MGT increased with the use of LPG and decreased by the usage of biogas.
