Direct injection compression ignition engines have proved to be the best option in heavy duty applications like transportation and power generation, but rapid depleting sources of conventional fossil fuels, their rising prices and ever increasing environmental issues are the major concerns. Alternate fuels, particularly biofuels are receiving increasing attention during the last few years. Biod...

Biodiesel is a green fuel produced from renewable resources. It is a clean-burning alternative fuel, which has drawn the attention of energy researchers for the last two decades. This paper presents an experimental investigation on Alexandrian laurel oil as a potential feedstock for biodiesel development. Biodiesel was produced using a two-step esterification–transesterification process. Analys...

Abstract Due to the enormous of fossil fuels and ensuing increase in automobiles, an unprecedented scenario has arisen with pollution levels that are out human control. In this study, a fuzzy logic model is developed predict how well spark-ignition engine running on gasoline ethanol mixes would operate. A test was operated pure gasoline–ethanol fuel mixtures range ratios at varying speeds. orde...

Over many decades, isolated regions (e.g., islands, rural and remote areas) have heavily relied on diesel engine for producing power energy. However, due to depleting fossil fuels concerning emissions, biodiesels could be the substitute in generation sectors. This study developed a single-zone thermodynamic model predict performances such as brake (BP), torque, thermal efficiency (BTE), brake-s...

Biodiesel from waste sources can be considered as the cheapest and most viable fuel alternative to depleting mineral diesel. In this work, biodiesel has been produced different of oil; grilled chicken oil (GCWO) which is animal based source cooking (WCO) vegetable using transesterification method. The impact variables such temperature, time, amount catalyst on conversion yield were investigated...

In this experimental study, the effect of alcohol (ethanol and methanol) use on the performance, emissions and combustion characteristics of a low power single-cylinder engine described the rated power output of the engine e.g. 2 kW were investigated and the results were compared with conventional gasoline operation. The tests were performed at full-throttle valve opening and variable engine sp...

The use of biodiesel, the methyl esters of vegetable oils are becoming popular due to their low environmental impact and potential as a green alternative fuel for diesel engine. The aim of this study is to potential use of Pongamia oil methyl ester as a substitute for diesel fuel in diesel engine. Various proportions of Pongamia and Diesel (B25, B50, B75, and B100) are prepared by transesterifi...

In order to improve the performance of a V-type diesel engine at low and medium speeds, compound VGT-STC turbocharger system was proposed. First, bench established, which allowed switch between VGT STC boosting systems. Then, load characteristic tests with variable vane opening were conducted different speeds in 1TC 2TC, respectively. The results showed that VGT-1TC could provide much more air ...

Higher alcohols can be included as a third component in biodiesel-diesel mixtures to improve fuel properties and reduce emissions. Determining the optimum concentrations of these fuels according purpose engine use is important both environmentally economically. In this study, eight different diesel (D), waste oil derived biodiesel (WOB), 1-pentanol (P) ternary were determined by design experime...
