TL;DR: In this article, the results of various researchers from different countries who prepared bio-fuels from vegetable oils and animal fats were reviewed and it was concluded that the use of biofuels as an alternative fuel for compression ignition engines improves the performance and emissions by adopting suitable combustion improvement methods.
Abstract: This paper reviews the results of various researchers from different countries who prepared biofuels from vegetable oils and animal fats. The performance and emission characteristics can be improved by blending with petrodiesel, changing the fuel injection parameters, adding oxygen-rich fuel additives and employing intake air oxygen enrichment methods. NOx emissions can be minimised by using exhaust gas recirculation techniques. From this review, it can be concluded that the use of biofuels as an alternative fuel for compression ignition engines improves the performance and emissions by adopting suitable combustion improvement methods.

TL;DR: An improved liquid diesel fuel for diesel engines is made by incorporating at least 0.003% by weight of a mixture of an iron salt of an aromatic nitro acid and a nitroaliphatic compound having one to four carbon atoms, into the diesel fuel.
Abstract: An improved liquid diesel fuel for diesel engines is made by incorporating at least 0.003% by weight of a mixture of an iron salt of an aromatic nitro acid and a nitroaliphatic compound having one to four carbon atoms, into the diesel fuel. The weight ratio of the aromatic nitro acid salt to the nitroaliphatic compound ranges from 1:10 to 1:100. The additive, when added to diesel fuel, (1) substantially eliminates hard carbon deposits from the valve and exhaust systems of diesel engines, thereby improving the efficiency of the engines and decreasing overhaul expense, (2) reduces air pollutants such as oxides of sulphur and nitrogen, and virtually eliminates carbon monoxide from diesel exhausts and (3) reduces or substantially eliminates slime deposits which form during diesel fuel storage.

TL;DR: In this article, a comprehensive comparative study of methanol and compressed natural gas (CNG) as transportation fuels is presented, and the authors find that no single alternative fuel is best in all categories.
Abstract: Concern over the environment and a potential oil shortage has resulted in an intensified research for alternative fuels for the transportation sector. Two fuels given strong consideration are methanol and compressed natural gas (CNG). This paper is a comprehensive comparative study of methanol and CNG as transportation fuels. The physical properties of methanol and CNG are discussed. The various concerns, such as source and potential fuel supply, safety, toxicity and health hazards, engine performance and emissions, fuel storage, fuel tank and refueling of these alternative fuels are addressed briefly in this paper. The authors find that no single alternative fuel is best in all categories. The merits and drawbacks of each fuel are tabulated and the vehicle characteristics are compared with gasoline. The study concludes that the neat methanol may be considered as an alternative for passenger cars and CNG may be considered for fleets, light and heavy-duty vehicles as the best near-term solution.

TL;DR: In this article, high-speed natural light (or chemiluminescence) imaging and simultaneous in-cylinder pressure data measurement and analysis were used to understand the fundamental influence of both low and high carbon content in alcohol fuels on turbulent flame propagation and subsequent mass burning with the potential to solidify butanol's reputation as a possible mainstream fuel additive.

TL;DR: In this paper, a four stroke four cylinder diesel engine was adopted to study engine power, torque, break specific fuel consumption, break thermal efficiency and exhaust temperature with the fuel of fraction methanol in diesel.
Abstract: A comprehensive study on the methanol as an alternative fuel has been carried out. A four stroke four cylinder diesel engine was adopted to study engine power, torque, break specific fuel consumption, break thermal efficiency and exhaust temperature with the fuel of fraction methanol in diesel. In this study, the diesel engine was tested using methanol blended with diesel at certain mixing ratio of 10:90, 20:80 and 30:70 of methanol to diesel respectively. The performance of the engine using blended fuel compared to the performance of engine with diesel fuel. Experimental results showed that the output power and torque for diesel fuel is lower compared to methanol-diesel blended fuel at any ratio. The best mixing ratio that produced the lowest exhaust temperature was at 10% of Methanol in 90% of Diesel fuel. The exhaust temperature for diesel fuel was higher compared to any mixing of the blended fuel. The brake specific fuel consumption for the three mixing ratios was not varying significantly but the lowest was for 30% Methanol and 70% Diesel. The specific fuel consumption for diesel fuel was much lower compared to any mixing ratio. It was noticed that brake thermal efficiency was thus improved in almost all operation conditions with the methanol and diesel blended fuels.
