Advances in biodiesel, emulsified diesel and artificial chemical additives are driven by consumer demand to save energy and reduce emissions from diesel engines. However, the effect of emulsified bio-solution/palm-biodiesel/diesel blends in diesel engines has not been assessed. Experimental...

Homogeneous charge compression ignition (HCCI) combustion mode provides very low NOx and soot emissions; however, it has some challenges associated with hydrocarbon (HC) emissions, fuel consumption, difficult control of start of ignition and bad behaviour to high loads. Cooled exhaust gas...

Oxygen-enriched combustion of diesel engine can reduce smoke emission and improve thermal efficiency, but also lead to the increase of NO emission. In this research, experiments were conducted on a turbo-charged direct injection diesel engine under the two conditions of 2000 rpm and 180 Nm...

In the current work, the effect of using CPO (crude palm oil)–OD (ordinary diesel) blends as fuel on the performance of CI (compression ignition) engine is studied. Three different blends of CPO–OD (25%, 50% and 75%) were investigated using direct-injection, stationary diesel engine. The...

The interest in energy from biomass, in particular for transportation, is related to the need to differentiate the energy sources to improve environment and protect human health. Objective of this study is a comparative evaluation of performance and exhaust emissions of an automotive diesel...

The usage of neat cashew nut shell oil (CSNO) as a fuel in direct injection diesel engine suffers from the problems of incomplete combustion and low brake thermal efficiency due to high viscosity. To overcome this problem, the CSNO was blended with camphor oil (CMPRO) which is less viscous and...

Biofuel is a prominent alternative fuel because of its environmental benefits and similar physiochemical properties to diesel fuel. This study investigated the impact of high quality refined, bleached and deodorized (RBD) coconut oil blends and fuel throttle setting on performance and exhaust...

The effects of ethanol fumigation on the inter-cycle variability of key in-cylinder pressure parameters in a modern common rail diesel engine have been investigated. Specifically, maximum rate of pressure rise, peak pressure, peak pressure timing and ignition delay were investigated. A new...

In this paper, a waste heat recovery system is proposed where a high speed turbocharged diesel engine acts as the topper of a combined cycle with exhaust gases used for a bottoming Rankine cycle. The paper describes a mathematical model to evaluate the performance of Rankine cycle system with a...

Energy recovery has been found to be a promising approach for disposal of polymer waste such as expanded polystyrene (EPS) which entraps large volume of air. Biodiesel known as an advantageous alternative fuel possesses bio-solvent attributes and is feasible to be used for energy recovery from...
