Abstract

The purpose of this paper is to conduct an experimental research on the impact of mixing ratio of biodiesel from waste cooking oil and an innovative diesel fuel (in which a renewable component is contained) on the emissions of an up-to-date light and compact small engine that has a leading role in city cars and urban vehicles. Two blends’ mixing ratios (20% and 40% by volume) were tested and the results were compared to those obtained when the engine was operated with low sulfur diesel (ULSD) and ULSD blended with 15% by volume of renewable diesel. The results indicate that diesel+ enhances CO and HC emissions in the exhaust as regards ULSD. Blending diesel+ with WCO causes a further reduction for most of the engine operative field. Concerning particulate emission, accumulation mode dominates for all fuels. Diesel+ is always characterized by lower mean diameters as regards ULSD. The addition of WCO further reduces the court mean diameter. Particle number concentration obtained by fuelling the engine with B40 is the lowest as regards all the other tested fuels. Concerning , a moderate increase of the emission was observed when fuelling the engine with diesel+, net or in blends.

以汽油柴油、绿色柴油及废烹调油混合燃料作燃料的柴油引擎的排放表现

本文的目的是进行一项实验研究，研究从废食用油中提取的生物柴油和一种创新的柴油燃料(其中含有可再生成分)的混合比例对在城市汽车和城市车辆中起主导作用的最新轻型紧凑型小型发动机的排放的影响。测试了两种混合物的混合比(20%和40%体积比)，并将结果与发动机使用低硫柴油(ULSD)和低硫柴油与15%体积比的可再生柴油混合时的结果进行了比较。结果表明，柴油+增加了废气中CO和HC的排放。将柴油+与WCO混合会使大多数发动机的工作领域进一步减少。在颗粒排放方面，所有燃料的累积方式都占主导地位。Diesel+的特点是在ULSD方面的平均直径较低。WCO的加入进一步减小了法院的平均直径。用B40为发动机加油获得的颗粒数浓度是所有其他测试燃料中最低的。此外，当使用柴油+、净柴油或混合柴油为发动机加油时，观察到排放的适度增加。
