Zustand: Sehr gut. Zustand: Sehr gut | Sprache: Englisch | Produktart: Bücher | TiO2 and CuO nanoparticles are investigated as potential additives to diesel fuel to reduce emissions and enhance engine performance. Various concentrations of nanofuels are examined under different loads to accurately determine their influence in combustion process. The measured emissions are CO, CO2, NO, O2, unburned HC meanwhile the mechanical parameters are BSFC, brake power, RPM, thermal efficiency and exhaust temperature. It is worth mentioning that the experimental work was conducted on two conditions; cold start and hot start.…

Zustand: Sehr gut. Zustand: Sehr gut | Sprache: Englisch | Produktart: Bücher | In this research, we could achieve a new route through introducing an insulating material with lower thermal conductivity and lower cost. The polyurethane foam and rice straw composite proved to have a higher efficiency than the pure polyurethane foam through the insulation properties, mechanical properties and the overall cost. The thermal conductivity of this new composite is 12% lower than that of the polyurethane foam with thickness reduction of also 12%. The advantage of this sample is also using a waste such as rice straw which is easily available for free. Rice straw is a good selection as a filler due to its low thermal conductivity which improves the material insulating properties. Consequently, this results in reducing the cost of insulation by 28.35%.…

Zustand: Hervorragend. Zustand: Hervorragend | Sprache: Englisch | Produktart: Bücher | Gasoline produced in Egypt is a low-grade gasoline that contains high concentration of harmful components that are having a toll on our environment. In addition, those pollutants cause countless diseases and deaths annually to the Egyptian population. This paper targets two main sectors in the production of commercial gasoline. The improvement engine efficiency through the upgrading of octane number is first experimented by using a blendstock that ranges from gasoline fractions and Isomerates. An optimum was then chosen depending on the results obtained from different tests. Through those experiments, it was determined which samples obeyed the EU regulation for transportation emissions. Having an excellent gasoline with a high octane number but produced large quantities of harmful emissions was unacceptable. This leads to the section aim of this research, which was to produce an environmental gasoline. This meant that once the gasoline sample is combusted, it should produce limited amounts of emissions such as 1% benzene since benzene is carcinogenic.…

Zustand: Hervorragend. Zustand: Hervorragend | Sprache: Englisch | Produktart: Bücher | Chemically, polymers are long chain molecules of very high molecular weight, often measured in hundreds of thousands. For this reason, the term macromolecules are frequently used when referring to polymeric materials. Any polymer sample consists of many chains of different lenghths. A polymer should constitute of a large number of simple repeated building units called monomers, the number of which is termed as degree of polymerization the first polymer used were natural products, specialty cotton, starch, protein and wool. Beginning in the twentieth century systemic polymers were made as Bakelite and nylon showed that tremendous possibilities of the new material.…
