External oil supply risk is an important aspect of energy security and oil import diversification is viewed as one of the most effective measures to reduce supply risk. By using the diversification index approach, this research attempts to assess external oil supply risks of oil importers with...

The micro combustor is the key component of the micro TPV power generator. To obtain high power density and performance efficiency, it is important for a micro combustor to achieve a high and uniform temperature distribution along the wall. In this paper, we compare the performance of a micro...

The demand for energy sources that are compact, lightweight and powerful has significantly increased in recent years. Traditional chemical batteries which are highly developed are unable to meet the demand for high energy intensity. This gap is expected to widen in the future as electronic...

A novel emulsion fuel with 82.4% diesel, 5% water and 12.6% nano-organic additives by volume is introduced in this work. Unlike other emulsion fuels (milky in color) developed around the world, it is green in color and very stable. The performance and emissions of the diesel engine fueled by the...

An experimental study was conducted on a Euro IV diesel engine to evaluate the performance, combustion and emission characteristics of pure biodiesel and its blend fuels. For each tested fuel, the performance and emissions were measured at four different engine speeds (800rpm, 1200rpm, 2400rpm...

This study numerically investigated knocking phenomenal of a RCCI (Reactivity Controlled Compression Ignition) engine fuelled with biodiesel and methanol. A reduced biodiesel/methanol chemical reaction mechanism coupled with 3D-CFD model was developed and applied to capture local pressure and...
