Among existing diesel engines, fuel improvement through additives is an attractive option to meet increasingly stringent pollutant emission regulations for diesel engines. Because of the good REDOX properties of rare earth materials, it can improve the combustion performance of diesel engines and reduce pollutant emissions. This paper characterizes the performance of inorganic acid rare earth and organic acid rare earth and analyzes the emission reduction performance from the crystal structure, which aim to compare the effects of inorganic acid rare earth and organic acid rare earth on the emission reduction performance of existing diesel engines under similar conditions. The emission reduction performance of two rare earth fuel additives of cerium carbonate and cerium stearate in Changchai twin-cylinder direct injection diesel engine at five rotational speeds is contrastively studied. The experimental results show that two kinds of rare earth fuel additives can effectively reduce NO X , CO and HC emissions of diesel engines. And the maximum reduction rate of NO X , CO and HC in cerium carbonate is 11.37%, 14.63% and 13.80% respectively, while the maximum reduction rate of NO X , CO and HC in cerium stearate is 10.19%, 12.15% and 9.40% respectively. Cerium stearate has higher NO X , CO, HC and PM emissions than cerium carbonate due to its small specific surface area. So the emission reduction effect of cerium carbonate is better than that of cerium stearate.

“…Поэтому для глубокоочищенных ДТ, допущенных к производству на территории Российской Федерации, разработан метод определения смазывающей способности ДТ на аппарате с высокочастотным возвратно-поступательным движением шарика (HFRR), по которому диаметр пятна износа должен быть не более 460 мкм 1 . Решением проблемы снижения противоизносных свойств стало добавление веществ на основе жирных кислот и их производных, которые повышают смазывающую способность [4][5][6]. Также в производстве ДТ используются цетаноповышающие, депрессорно-диспергирующие и др.…”

In conformity with a constant tightening of environmental requirements, sulfur compounds are removed from the composition of diesel fuel using the hydrotreating method. However, this has led to a significant deterioration in the anti-wear properties of diesel fuel. To restore the lubricity, oxygen-containing compounds are added to diesel fuel, including carboxylic acids and their amide derivatives, as well as esters, polyamines and other organic compounds. The recommended concentration of the additive, which ranges from 0.015 to 1.0 wt %, is dependent on its specific properties. In addition to anti-wear additives, cetaneenhancing, depressant-dispersing and other additives are added to diesel fuel to correct the properties of the fuel. A method for producing an esterification product for improving the properties of diesel fuel is described. It is shown that an esterification product containing up to 65% fatty acid esters can be obtained at a temperature of 110–115 °С and a process duration of 120–240 minutes when using 3–5 wt % ion-exchange resins for fatty acids. The effect of the additive content on the lubricating properties of diesel fuel is investigated. When 0.5 wt % or more is added, the corrected wear spot diameter is reduced from 615 to 420 µm; when 1.5 wt % is added, it is further reduced to 230 µm. The addition of esterification product to the diesel fuel is shown to result in an increase in the cetane number of initial fuel. When adding 6.0 wt % of the esterification product under development, the cetane number of the fuel is increased from the original 43.0 units to 51.6. In this case, the esterification product can be used as a component for preparing a mixture of biodiesel fuel B6-B20, according to GOST 33131-2014.
