Performance And Emission Characteristics of Bio Diesel from Pongamia Oil, Methanol, Koh and Its Effects on Ci Engine

Performance And Emission Characteristics of Bio Diesel from Pongamia Oil, Methanol, Koh and Its Effects on Ci Engine

Biodiesel can be produced from a wide variety of plant oils, both edible and non-edible biodiesel in most of the developed countries are being produced from sunflower, peanut, palm and several other feed stocks which are essentially edible in Indian context. Therefore, in the developing countries such as India, it is desirable to produce biodiesel from the non-edible oils which can be extensively grown in the waste lands of the country. The economic feasibility of biodiesel depends on the price of crude petroleum and the cost of transporting diesel over long distances to remote areas. It is a fact that the cost of diesel will increase in future owing to increase in its demand and limited supply. A great deal of research and development on internal combustion engines has taken place not only in the design area but also in finding an appropriate fuel. Many researchers have concluded that biodiesel holds promise as an alternative fuel for diesel engines, since its properties are very close to diesel fuel. The fuel properties of biodiesel such as cetane number, heat of combustion, gravity, and viscosity influence the combustion and so the engine performance and emission .

Performance, Emission and Combustion Characteristics of a Diesel Engine with Methyl Ester of Mango Seed Oil and Diesel Blends

India is importing crude petroleum and petroleum products from Gulf countries. Indian scientists searched for an alternate to diesel fuel to preserve the global environment and to withstand the economic crisis. As far as India is concerned because of its vast agro forestry base, fuels of bio origin can be considered to be ideal alternative renewable fuels to run the internal combustion engines. Vegetable oils from plants both edible, non-edible and methyl esters (Biodiesel) are used as an alternate source for diesel fuel. Biodiesel was found to be the best alternate fuel, technically, environmentally acceptable, economically competitive and easily available. There are more than 350 oil bearing crops that have been identified, among which only sunflower, soyabean, cottonseed, mango seed, rapeseed and peanut oils are considered as potential alternative fuels for diesel engines. Apart from the renewability, the advantages of biofuel are: High oxygen content, higher flash

Experimental Investigation on CI Engine for Performance, Emission and Combustion Characteristics of Dual Biodiesel Blended In Diesel

Experimental Investigation on CI Engine for Performance, Emission and Combustion Characteristics of Dual Biodiesel Blended In Diesel

BTE for conventional diesel is greater than its blends. The variations in the thermal efficiency of the biodiesel blends are due to the lower calorific value of WCOBD & PSBD when compared to diesel. Further, higher viscosity and slow vaporization of biodiesel present in these blends leads to inferior combustion of biodiesel which causes reduction in brake thermal efficiency [4, 5, 6]. It is noticed that as the biodiesel is blended with diesel for all proportions, brake thermal efficiency decreases.

compression ratio, benefits of GTL having high CN disparages as decreased pre-mixed phase of combustion results higher soot emissions. In spite of high tolerance of GTL fuel to EGR level, an abrupt increment in soot emission has been observed at higher levels of EGR. Lower distillation properties of GTL ensures improved atomization with uniform dispersion of fuel spray initiating rapid evaporation that lead towards proper combustible air-fuel ratio. Introducing pilot injection in association with common rail injection system (independent of fuel properties) favors the reduction in combustion noise with the support from lower heat release rate of GTL fuels. Pump-line–nozzle type fuel injection system (affected by fuel properties) engines fuelled by GTL demonstrates later injection timing compared to conventional diesel. The optimization of after-treatment system for zero sulfur fuel improves NO x reduction efficiency, because the catalyst can be designed to improve a low temperature

Experimental Study on Ci Engine Performance Using Bio Diesel Blends

petroleum products as a fuel for its running. Due to urbanization and increased population usage of no. of automobiles increased and consumption of petroleum products increased so continuous demand for the energy consumption increased from year to year as a result reserves of petroleum product are depleting in a faster rate. If this trend continuous in the same way entire world may face problem with shortage of petroleum products. Therefore it is necessary to find alternative fuels to be used in the standard internal combustion engine to bridge this gap of increased consumption. Simultaneously it is necessary to improve the combustion engine in terms of fuel efficiency and emissions. As we know so far petroleum based fuels are giving higher efficiency as compared with alternative fuels so to reduce the fuel consumption strict measures to be adopted to control the consumption and also alternative fuels to be developed to mix with the petroleum fuels so that petroleum product reserves will go for longer period and it will meet with increased demand. Otherwise once these fossil fuels are consumed means again it won’t exist in nature because of its non- renewable nature. So in this paper focus is given to increase the existence of non-renewable fuels by reducing its consumption with addition of suitable proportions of bio-fuels. In that context importance is given one is to improve the technology to increase the kilometers per hour of unit fuel consumption by improving the suitable modifications in the engine design and other is reducing the fuel consumption by adding renewable blends so petroleum products may last for several years. Here an experimental attempt is being made to reduce the consumption of fossil fuels (petroleum products) by adding bio-diesel blends of small quantities of renewable fuels. It will help to reduce the consumption of petroleum products hence longer period of reserves may be achieved. More over

Bio-Diesel production and Effect of Catalytic Converter on Emission performance with Bio-Diesel Blends

Bio-Diesel the word itself defines almost all the features of the Bio-Diesel literary. In the Era of this Global Warming where the people are making their living more and more comfortable and they are deteriorating the environment also. The uses of the automobiles with the conventional source of fuel leads to the production of the toxic gaseous substances like carbon monoxide, carbon dioxide, oxides of nitrogen, oxide of sulphur, hydro-carbons etc. The limitation comes with the rise in the price of the fuel as well as the produce of the green house gases as the exhaust gas. In the present study, a new method has been employed to produce Bio-Diesel in a homely basis. The production of the Bio-Diesel is done by using Bio-Diesel processor. It requires the used vegetable oil, methanol and the lye with the accurate proportionate. Generally, emissions of regulated compounds changed linearly with the blend level. The objective is to detect any posit ive or negative effects depending on blend levels, because conventional diesel fuel and biodiesel can be blended in every ratio. The known positive and negative effects of biodiesel varied accordingly and investigate the effect of Catalytic Converter on emission performance with Bio- Diesel Blends.
