In the present study, experimental analyses were conducted by using biodiesel derived from second-generation feedstock. terms of cost and accessibility, feedstock has gained more attention due to its environmental approach. Waste-cooking-oil-derived methyl ester was produced through a transesterification reaction in presence synthesized magnesium zirconate (Mg2Zr5O12) heterogeneous catalyst. Th...

The major aim of the research is to investigate ability biogas as an alternative fuel for gasoline-powered Spark Ignition (SI) engine. In this study, biogas/gasoline mixtures containing different ratios biogas, gasoline, and were tested in SI engine with increased compression ratio at loads constant speed. According comparison utilization generally decreased Brake Thermal Efficiency (BTE), whil...

A direct injection (DI) diesel engine is tested with different biodiesel-diesel blends, such as B0 (neat diesel), B5 (i.e., 5 vol. % biodiesel and 95 vol. % diesel), B10 (10 vol. % biodiesel), B20 (20 vol. % biodiesel), B50 (50 vol. % biodiesel), and B100 (neat biodiesel) for performance and emissions under different load conditions. Engine performance is examined by measuring brake specific fu...

Experimental investigations carried out on a single-cylinder four-stroke motorcycle spark ignition engine operating on gasoline and natural gas are reported in the present paper when compressed natural gas (CNG) and hydrogen were used as fuel. The investigations were carried out by mixing a small percentage of hydrogen (5 to 30%) with CNG and supplied to the engine. Hydrogen and CNG were mixed ...

As an alternative fuel biodiesel can be played an important role to meet the future energy demand. Biodiesels have lot of good advantages over diesel which attract the users to use it as the substitute of diesel. It has huge biodegradability, less environmental impact, higher flash point and cetane number, higher lubricity and so on. However, for the widespread practical applicability of biodie...

The aim of this study was to find out the thermal and environmental performance a four-stroke, single-cylinder, direct injection 10-kW CI engine at varying load conditions using different test fuels. formulated fuels, viz. CeO2 nanoparticles-dispersed water–diesel–biodiesel fuel blend (CNWEDB) (WEDB), were prepared emulsification technique nanoparticles water as additives in diesel–biodiesel (B...

Reducing fuel consumption is a major goal for the aviation community due to environmental concern and fuel price uncertainty. The Federal Aviation Administration (FAA) is currently developing and implementing Air Traffic Management (ATM) technologies to ensure reliable operational performance that is robust to delays caused by congestion and weather. These technologies will reduce planned and u...

In this study, we investigated the effects of canola oil biodiesel (BD) to improve combustion and exhaust emissions in a common rail direct injection (DI) diesel engine using BD fuel blended with diesel. Experiments were conducted with BD blend amounts of 10%, 20%, and 30% on a volume basis under various engine speeds. As the BD blend ratio increased, the combustion pressure and indicated mean ...

The increase in fuel price is constraining car manufacturers to produce highly efficient engines with more regulations in terms of pollutant emissions. The increasing complexity of modern engines has rendered the prototyping phase long and expensive. This is where engine modeling becomes in the recent years extremely useful and can be used as an indispensable tool when developing new engine con...

In this study, the principal objective is to compare performances of an air-cooled one cylinder, four-stroke direct injection diesel engine using blends (5% by volume B5, 10% B10) and biodiesels derived respectively from palm oil, castor oil raphia sese De Wild with pure diesel. All used in work come plant species democratic republic Congo as listed above. The (power, torque brake specific cons...
