The world is getting modernized and industrialized day by day. As a result vehicles and engines are increasing. But energy sources used in these engines are limited and decreasing gradually. This situation leads to seek an alternative fuel for diesel engine. Biodiesel is an alternative fuel for diesel engine. The esters of vegetables oil animal fats are known as Biodiesel. This paper investigat...

The performance, emission and combustion characteristics of a single cylinder four stroke variable compression ratio multi fuel engine when fueled with different blends of rice bran oil methyl ester and ethanol are investigated and compared with the results of standard diesel. Bio diesel produced from Rice bran oil by transesterification process has been used in this study. Experiment has been ...

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...

Falling oil revenues and rapid urbanization are putting a strain on the budgets of oil producing nations which often subsidize domestic fuel consumption. A direct way to decrease the impact of subsidies is to reduce fuel consumption by reducing congestion and car trips. While fuel consumption models have started to incorporate data sources from ubiquitous sensing devices, the opportunity is to ...

Continued legislative pressure to reduce exhaust emissions from CI (compression ignition) has resulted in the development of advanced fuel injection equipment. This advanced injection system produces higher temperatures and pressures at the injector tip, where deposit formation is initiated. In this research, an endurance test was carried out for 250 h on 2 fuel samples; DF (diesel fuel) as bas...

In this study, the biodiesel produced from cottonseed oil was prepared by a method of Transesterification and its blends of 25%, 50%, 75% and 100% in volume, and standard diesel fuel separately. The effects of biodiesel addition to diesel fuel on the performance, emissions and combustion characteristics of a naturally aspirated DI compression ignition engine were examined. Biodiesel has differe...

Crude oil is one of the most important energetic resources in the world. It is used as raw material in numerous industries, including the refinery-petrochemical industry, where crude oil is refined through various technological processes into consumer products such as gasoline, oils, paraffin oils, lubricants, asphalt, domestic fuel oil, vaseline, and polymers. Oil-derived products are also com...

The aim of the thesis is to describe how the minimum biofuel requirement affects the monopolistic oil markets. This is an increasingly important questions, because the governments are smoothing the biofuel’s way into the fuel markets for both the economical and environmental reasons. The focus in this thesis is mainly on the minimum biofuel requirement, but at times that policy is compared also...
