Abstract

Waste utilisation and emission of greenhouse gases are two of the world's most pressing challenges today. This study seeks to solve the problem generated by the disposal of Waste Cooking Oil (WCO) as a tiny step forward in contributing to the reduction of waste disposal. WCO has a high potential as a bio fuel for internal combustion engines, hence it was chosen for this investigation. WCO of 20% and diesel 80% is used. This study looks at the performance, combustion and emission parameters of a dual fuel compression ignition engine running on WCO biodiesel with a hydrogen additive at atmospheric condition. The parametric study include variation in engine load (0-18 kg) and hydrogen flow rate (3, 6, 9 LPM). The experiment was conducted on a four-stroke diesel (computerized), single cylinder, water cooled power at 5.2 kW at 1500rpm Kirloskar engine. From the experiment overall parametric variation of 35.38%, 34.06% and 32.37% of brake thermal efficiency was obtained and emission was observed. However, with increase of hydrogen flow rate resulted in increased engine performance, increase in CO, NOx and reduction in emission of UBHC and CO2.

使用柴油-废烹饪生物柴油混合燃料时，氢对CI发动机减排的影响

废物利用和温室气体排放是当今世界面临的两个最紧迫的挑战。本研究旨在解决因处理废食用油而产生的问题，作为减少废物处理的一小步。WCO作为内燃机的生物燃料具有很高的潜力，因此选择它作为本研究的对象。WCO为20%，柴油为80%。本研究考察了常压条件下WCO生物柴油加氢双燃料压缩点火发动机的性能、燃烧和排放参数。参数研究包括发动机负荷(0-18 kg)和氢气流量(3、6、9 LPM)的变化。实验是在一台四冲程柴油(计算机化)，单缸，水冷动力5.2 kW, 1500rpm的Kirloskar发动机上进行的。实验结果表明，制动热效率总体参数变化幅度分别为35.38%、34.06%和32.37%，并对排放进行了观测。然而，随着氢气流量的增加，发动机性能提高，CO、NOx排放量增加，UBHC和CO2排放量减少。
