Abstract 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.

SI发动机不同节气门位置汽油、沼气和LPG燃料对发动机性能和尾气排放影响的研究

摘要 在本研究中,对不同节气门位置的单缸四冲程火花点火(SI)发动机使用不同体积百分比的汽油、液化石油气(LPG)和沼气燃料进行了实验。在实验中,比较了使用汽油、沼气和液化石油气获得的数据;制动热效率 (BTE)、气缸压力、平均气体温度 (MGT)、制动比燃料消耗 (BSFC)、二氧化碳 (CO2)、一氧化碳 (CO)、碳氢化合物 (HC) 和氮氧化物 (NOx) 排放。根据结果​​,在全节气门开度(FTO)下使用沼气和液化石油气,与使用汽油相比,BSFC 分别增加了 75.52% 和 34.19%,而与使用汽油相比,BSFC 分别增加了 16.04% 和 8.95%。 BTE 已确定。另一方面,与汽油相比,使用沼气和液化石油气后,CO 排放量减少 15% 和 62.03%,HC 排放量减少 23% 和 63%,CO2 排放量减少 6.77% 和 56.42%。在半节气门开度(HTO)中,BSFC分别增加了85.2%和45.51%,而BTE分别下降了33.43%和20.22%。此外,检测到二氧化碳排放量减少 15.97% 和 47.65%,HC 排放量减少 21.19% 和 62.38%,二氧化碳排放量减少 6.84% 和 69.54%。在气瓶压力值方面,使用沼气和液化石油气,气瓶压力分别下降约 17.76% 和 24.41%。另一方面,与汽油相比,MGT 会随着 LPG 的使用而增加,而随着沼气的使用而减少。与汽油相比,检测到的二氧化碳排放量减少了 42%。在半节气门开度(HTO)中,BSFC分别增加了85.2%和45.51%,而BTE分别下降了33.43%和20.22%。此外,检测到二氧化碳排放量减少 15.97% 和 47.65%,HC 排放量减少 21.19% 和 62.38%,二氧化碳排放量减少 6.84% 和 69.54%。在气瓶压力值方面,使用沼气和液化石油气,气瓶压力分别下降约 17.76% 和 24.41%。另一方面,与汽油相比,MGT 会随着 LPG 的使用而增加,而随着沼气的使用而减少。与汽油相比,检测到的二氧化碳排放量减少了 42%。在半节气门开度(HTO)中,BSFC分别增加了85.2%和45.51%,而BTE分别下降了33.43%和20.22%。此外,检测到二氧化碳排放量减少 15.97% 和 47.65%,HC 排放量减少 21.19% 和 62.38%,二氧化碳排放量减少 6.84% 和 69.54%。在气瓶压力值方面,使用沼气和液化石油气,气瓶压力分别下降约 17.76% 和 24.41%。另一方面,与汽油相比,MGT 会随着 LPG 的使用而增加,而随着沼气的使用而减少。使用沼气和液化石油气,钢瓶压力分别下降约 17.76% 和 24.41%。另一方面,与汽油相比,MGT 会随着 LPG 的使用而增加,而随着沼气的使用而减少。使用沼气和液化石油气,钢瓶压力分别下降约 17.76% 和 24.41%。另一方面,与汽油相比,MGT 会随着 LPG 的使用而增加,而随着沼气的使用而减少。
