The Impact of Bioesters on Lubricity of Diesel Fuels
نویسندگان
چکیده
The paper discusses the influence of two fatty acid methyl esters (bioesters) derived from soybean oil (SME) and from rapeseed oil (RME) on the lubricity of the petroleum diesel fuels: Ekodiesel (S:26 mg/kg, HFRR: 555 m) and Citydiesel (S: 8 mg/kg, HFRR: 617 m). High-frequency reciprocating rig (HFRR) equipment was used to examine diesel fuels, neat bioesters and blends containing from 0,1 % up to 20 % of soybean ester or rapeseed ester in each reference fuel. Lubricity evaluation was based on the measurement of the diameter of the wear scar left on the oscillated ball being in contact with a stationary disc submerged in the examined fuel. The examinations have shown that soybean ester is the most effective additive enhancing the lubricity of both base diesel fuels, but the changes in the lubricity were more dynamic for the diesel fuel with higher level of sulphur.

متن کاملMicroalgae : The Future Fuel ( Review )
Petroleum prices are increasing day by day and for fueling we are completely dependent on the fossil fuels. Sources of fossil fuels are depleting continuously due to the increasing demand of petroleum products. Renewable carbon neutral transport fuels are necessary for environmental and economic sustainability. There are many options in this area, but unlike solar, nuclear, and fossil fuels, bi...
متن کاملNear-frictionless Carbon Coatings for Use in Fuel Injectors and Pump Systems Operating with Low-sulfur Diesel Fuels
While sulfir in diesel fuels helps reduce friction and prevents wear and galling in fuel pump and injector systems, it also creates environmental pollution in the form of hazardous particulate and S02 emissions. The environmental concern is the driving force behind industry’s efforts to come up with new alternative approaches to this problem. One such approach is to replace sulfur in diesel fue...
