Abstract

About one-third of passenger vehicles available in the world market are diesel powered, which leads to greater emphasis on improving the performance of a diesel engine without changing the engine configuration. In this study, an attempt has been made to improve the combustion efficiency of nanofuel, CeO2 nanoparticles dispersed diesel. It was prepared using a tip sonicator with different concentration of ceria varied in the range of 0.02, 0.04, 0.06, 0.08, and 0.10 wt. % in diesel. Cerium concentration in diesel played an important role to control the concentration of toxic exhaust gases by influencing the complete combustion of fuel. The maximum reduction of emission gases and an increase of engine performance were observed at an optimum condition of 75 % of load and 0.06 wt. % of CeO2 in diesel, where brake thermal and mechanical efficiency were increased by 10 % and 7 %, respectively and the specific fuel consumption, NOx, and CO was found to be decreased by 10 %, 50 %, and 40 %, respectively. It is concluded that the use of nanofuel is a very efficient tool to protect our environment from the toxic gases emitted from the burning of fossil fuel.

利用纳米燃料减少柴油机的排放——纳米二氧化铈分散柴油

世界市场上大约三分之一的乘用车是柴油驱动的，这使得人们更加重视在不改变发动机配置的情况下提高柴油发动机的性能。本研究尝试提高纳米燃料CeO2纳米颗粒分散柴油的燃烧效率。在柴油中，二氧化铈的浓度分别为0.02、0.04、0.06、0.08和0.10 wt. %。柴油中铈的浓度通过影响燃料的完全燃烧，对控制有毒废气的浓度起着重要作用。在负荷为75%、柴油中CeO2含量为0.06 wt. %的最佳条件下，最大限度地减少了废气排放，提高了发动机性能，制动热效率和机械效率分别提高了10%和7%，比油耗、NOx和CO分别降低了10%、50%和40%。结论是，纳米燃料的使用是一种非常有效的工具，可以保护我们的环境免受化石燃料燃烧产生的有毒气体的影响。
