Producing and using renewable fuels for transportation is one approach for sustainable energy future for the world. A renewable fuel contributes lesser global climate change. The present work reports on the utilization of liquified petroleum gas (LPG) as a primary fuel with diethyl ether (DEE)...

This paper presents the results of experimental work carried out to evaluate the exhaust emissions characteristics of ordinary Malaysian coconut oil (COCO) blended with conventional diesel oil (OD) fueled in a diesel engine. This project complies with Malaysian Government strategy on biofuel...

Improved thermal efficiency, reduction in fuel consumption and pollutant emissions from biodiesel fueled diesel engines are important issues in engine research. To achieve these, rapid and perfect air-fuel mixing are the most important requirements. The mixing quality of biodiesel spray with air...

An experimental study is conducted to evaluate the performance and exhaust emissions characteristics of diesel fuel blends with 8%, 16% and 24% (by vol.) diethyl ether (DEE), in a standard, experimental, single-cylinder, four-stroke, high-speed direct injection (HSDI), ‘Hydra’ diesel engine...

An experimental study is conducted to evaluate the effects of using blends of ethanol with conventional diesel fuel, with 5%, 10% and 15% (by vol.) ethanol, on the combustion and emissions of a standard, fully instrumented, four-stroke, high-speed, direct injection (HSDI), ‘Hydra’ diesel...

Many short-run studies point to the potential for direct fueling of compression ignition engines with plant oil fuels. There is a much smaller body of work that examines the potential for these fuels in long-run tests that illuminate engine endurance and longevity issues. Generally, longevity...

Diesel engine development for use in light-, medium- and heavy-duty road vehicles is mainly driven by more and more stringent emission standards. Apart from air quality related emissions such as nitrogen oxides and particulates, also greenhouse gas (GHG) emissions are likely to become of more...

In this experimental study, the influences of re-entrant combustion chamber geometry on a diesel engine emission, performance and on the combustion were investigated using Pongamia Oil Methyl Ester (POME). For this purpose, the pistons with Toroidal Re-entrant Combustion Chamber (TRCC) and...

Fat trap grease is a cheap source for biodiesel production, but until now its transformation into biofuel is not well studied. The effects of the use of biodiesel from degraded raw material on combustion in engines are not discussed by researchers. In this paper, engine tests were performed on...

In the paper, combustion and emissions of a multi-cylinder CI (compression-ignition) engine fueled with DMF–diesel, n-butanol–diesel and gasoline–diesel blends were experimentally investigated, and fuel characteristics of DMF, n-butanol and gasoline were compared. Diesel was used as the...
