Background The production of fuels and chemicals from renewable resources is increasingly important due to the environmental concern and depletion of fossil fuel. Despite the fast technical development in the production of aviation fuels, there are still several shortcomings such as a high cost of raw materials, a low yield of aviation fuels, and poor process techno-economic consideration. In r...

In today’s scenario, researchers around the world are looking for ways to develop alternate forms of fuel. With the ever-rising fuel costs, developing alternate energy is a top priority. Biodiesel was developed to combat the high gas and oil prices. It is especially made for use in diesel cars and trucks. Biodiesel can be made from all Natural foods that can produce oil. Virtually all oils that...

The relevance of this study is due to the need replace petroleum diesel fuel with motor fuels obtained from alternative raw materials. Rapeseed oil and ethyl alcohol are considered as promising fuels. use these biofuels a makes it possible solve problem reducing carbon dioxide emissions into atmosphere switch carbon-neutral energy. possibility using mixtures for engine considered. Poor flammabi...

Vegetable oils are renewable in nature and can be directly used as fuels in diesel engines. However, their high viscosity and poor volatility lead to reduced thermal efficiency and increased hydrocarbon, carbon monoxide and smoke emissions. Transesterification is one of the methods by which viscosity could be drastically reduced and the fuel could be adopted for use in diesel engine. This Ester...

A rapid compression machine (RCM) has been designed and built for investigating the autoignition characteristics of bio-derived jet and diesel fuels. The RCM has been designed with a particular emphasis on versatility, so that non-volatile fuels may be tested in a premixed gas phase, as a fuel spray, or as an aerosol in an oxidizing bath gas. A blend of these test approaches provides insight in...

agricultural waste biomass generated from agricultural production and food processing industry are abundant, such as durian  peel, mango peel, corn straw, rice bran, corn shell, potato peel and many more. due to low commercial value, these wastes are disposed in landfill, which if not managed properly may cause environmental problems. currently, environmental laws and regulations pertaining to ...

The use of bio-ethanol as an alternative diesel engine fuel is increasing rapidly. Bioethanol is mixed with diesel fuel in different ratios and used in CI and SI engines. Vibrations have direct effects on engine components and users when the engine is operated on a vehicle. For this reason, analysis of vibration resulting from combustion in IC engines is very important. In this study, evaluatio...
