Fossil fuels are still one of the world’s major sources of energy. Because of their reduced availability in the future, however, renewable resources like biodiesel provide an attractive substitute to meet the growing demand for energy supply. Signi

Anhydrous nanoscopic CuF2 is synthesized from alkoxides Cu(OR)2 (R=Me, tBu) by their reaction either in pure liquid HF at -70 °C, or under solvothermal conditions at 150 °C using excess HF and THF as solvent. Depending on the synthesis method, nano

The use of biodiesel as fuel for diesel engines can reduce emissions of hydrocarbons (HC), carbon monoxide (CO), and particulate matter (PM). Unfortunately, however, biodiesel tends to increase emissions of nitrogen oxides (NOx) (EPA, 2002) [1]. Prev

In consideration of the CO2 saving potentials of biofuels, a quota of biodiesel in fossil diesel fuel is established in a number of countries all over the world. However, primary investigations on fossil diesel fuel/biodiesel blends showed a certain

Due to the fact that modern diesel engines require very well-defined fuel properties to ensure high efficiency, low emissions and a long durability, the fuel properties and their determination methods have to be standardized. Most diesel fuel standar

The degradation of rapeseed oil methyl ester (RME) under accelerated conditions was investigated by use of total fluorescence spectroscopy (TFS). This technique provides an easy and quick analysis of natural antioxidants (e.g. vitamin E, chlorophylls

The combustion of chemicals in engines is much more than a transformation of chemical energy into kinetic energy. Fuel, engine and exhaust gas treatment form a unit with mutual dependencies and optimisation potentials. Above all, the creation of dies

This study presents the impact of adsorbents in augmenting the oxidative stability of biodiesel. Engine oil performance is affected by the use of biodiesel as it can accumulate in a vehicle’s sump and impact engine oil durability. This work aims to

An increasing use of renewable fuels in the transport sector reduces the dependency on fossil oil and lowers the emission of greenhouse gases. This is a prime political and economic goal in Europe and also in many other parts of the world. In the die
