Cost and limited reserves of conventional fossil fuels have intensified the search for alternative fuels for use in internal combustion engines. A possible alternative engine fuel is vegetable oil because it is a clean burning, renewable, non-toxic, biodegradable and environmentally friendly transportation fuel. It can be used in a neat form without any modification of the engine. Vegetable oil...

The worldwide concern regarding global warming has increased the interest of using biomass as a renewable and CO2 neutral source of energy. Pyrolysis oil (PO), as one of the most important product of biomass conversion, has the potential to be used as a fuel oil substitute in many applications for heat and electricity generation. However, pyrolysis oil properties and its behavior during combust...

The microemulsion is the emulsion with dimension of molecules approx. micrometre and smaller. Such microemulsion of water and diesel oil creates new quality and lets on obtainment ecological and economic of effects, as well as eliminates the disadvantageous influence common emulsions, or unprofitable effects of the injection of water to inlet system of the engine, direct to combustion chambers,...

Biodiesel is an alternative diesel fuel that can be produced from different kinds of vegetable oils. It is an oxygenated, non-toxic, sulphur-free, biodegradable, and renewable fuel and can be used in diesel engines without significant modification. However, the performance, emissions and combustion characteristics will be different for the same biodiesel used in different types of engine. In th...

The greenhouse gas emission intensity of refining lower quality petroleum was estimated from fuel combustion for energy used by operating plants to process crude oils of varying quality. Refinery crude feed, processing, yield, and fuel data from four regions accounting for 97% of U.S. refining capacity from 1999 to 2008 were compared among regions and years for effects on processing and energy ...

The combustion of straight vegetable oil (SVO) in internal combustion engines has shown conflicting results in emissions, power, and engine longevity. Many early studies suggested that SVO should not be considered for long term use in diesel engines. However, waste vegetable oil has been fueling adapted vehicles in progressive communities for years. The issues involved in the combustion of SVO ...

Viscosity of vegetable oil is considered a constraint for its use as an alternate fuel for Internal Combustion(IC) engines. In this experimental investigation, the viscosity of cottonseed oil (CSO), which is considered a potential alternate fuel, is reduced by blending it in different proportions with diesel, and its viscosity at various temperatures was analyzed and used as a fuel in a compres...

Diesel is a fossil fuel that is getting depleted at a fast rate. So an alternative fuel is necessary and a need of the hour. Neem oil, which is cultivated in India at large scales, has a high potential to become an alternative fuel to replace diesel fuel. Direct use of Neem oil cannot be done, as its viscosity is more than the diesel fuel, and hence affects the combustion characteristics. The N...

A research program on combustion performance evaluation of Canadian middle distillates was carried out at the Combustion and Carbonization Research Laboratory. The program was initiated in response to the needs of the oil industry as well as the standard writing bodies for better fuel quality specifications. The combined effects of industry's effort to maximize the product yield from a crude ba...
