The objective was to evaluate the effect of used engine oil on structural behavior of reinforced concrete elements. Six full-scale beam specimens were tested in three sets. The difference between the three sets was the mode of failure of the beams: flexure; shear; or bond. The two companion...
Nano-graphene lubricating oil with appropriate concentration shows excellent performance in reducing friction and wear under different working conditions of diesel engines, and has been widely concerned. Lubricating oil has a significant impact on partic

This paper investigates the characteristics of particle size distribution in exhaust gas of engine fuelled with pure diesel and with diesel mixed with base oil or with oil additives. The experiments are conducted on a turbocharged diesel engine with fast particulate spectrometer DMS 500 connected to ...
In order to investigate the performances and emissions of our fuels it was measured the engine power, the specific fuel consumption, smoke density and gas emissions such as nitrogen oxides (NOx) and total unburned hydrocarbons (HC). 展开 关键词: biodiesel sunflower oil diesel engine diesel ...
Biodiesel can be used in its pure form or can be blended with diesel to form different blends. The purpose of this research was to evaluate the potential of karanja oil methyl ester and its blend with diesel from 20% to 80% by volume. Engine performance and exhaust emissions were ...

For example, it has become expensive to design furnances for use of high-sulfur coals and fuel oils, and in piston-engine design there is a trade-off between efficiency of combustion and NO production. Consideration of these facts along with the previously discussed use of combustion in waste...
