This manuscript describes a rheological and tribological study carried out on eco-friendly lubricants. These ecolubricants were made up of nanoclays as dispersed phase (a layered nanosilicate (montmorillonite Cloisite 15A) fiber-like nanoclay (sepiolite Pangel B20)) vegetable-based oil continuous (castor (CO), high oleic sunflower (HOSO) their mixtures). A series nanoclay-based prepared by vary...

The purpose of this study is to investigate injection timing affected particle size distribution a diesel engine fueled with biodiesel/diesel blends. biodiesel blending ratios include 7, 10 and 20%vol. experiments were operated at speed 1,500 rpm under 25, 50 75% loads two different (25.5 CAD BTDC 27.5 BTDC). effects addition on the changes in black smoke discussed. Results showed that standard...

Abstract Determination of oxidation stability becomes a critical fundamental analysis to ensure biodiesel quality. The biodiesel’s degradation by may compromise fuel properties and engine durability due forming products fatty acid decomposition. In this present study, the palm-oil its blends with diesel (cetane number 48) was determined using EN 15751 (Rancimat Method) ASTM D 7545 (Rapid Small ...

Countries globally are focusing on alternative fuels to reduce the environmental pollution. An example is biodiesel fuel, which leading way other technologies. In this research, methyl esters of castor oil were prepared using a two-step transesterification process. The respective properties (Ricinus Communis) estimated ASTM standards. effect performance and emission diesel engines was noted for...

The optical response of the lowest-energy isomers of the B20 family is calculated using time-dependent density-functional theory within a real-space, real-time scheme. Significant differences are found among the absorption spectra of the clusters studied. We show that these differences can be easily related to changes in the overall geometry. Optical spectroscopy is thus an efficient tool to ch...

With their higher sustainability index, biofuels, environmentally-friendly and renewable nature is a viable alternative energy source in the transportation sector. This study presents effect of waste cooking oil (WCO) biodiesel on performance, combustion, emission from compression ignition engine. The was blended with diesel varying proportions 5% 95% (designated as B5), 10% (B10), 15% (B15), 2...

A one-port surface acoustic wave (SAW) resonator based on Co40–Fe40–B20/SiO2/ZnO/quartz multilayer structure and exhibiting a dual mode, Rayleigh Love modes, is investigated to achieve multifunctional sensor measuring both temperatures magnetic fields. The mode of the used for temperature measurement with sensitivity ?37.9 ppm/°C, field measurement. Co40-Fe40-B20 sensitive layer, quartz crystal...
