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...

We critically examine how evidence and knowledge are brokered between the various actors (agents) in regulatory decisions on risk. Following a précis of context and regulatory process, we explore the role power and personality might play as evidence is synthesised and used to inform risk...

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...

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...

The present study aims to numerically investigate the impacts of ethanol blend ratio together with advanced fuel injection timings on biodiesel’s performance, combustion and emission characteristics. Simulations were conducted using coupled KIVA–CHEMKIN code for neat biodiesel and its blend...
