A Review : Efficiency Improvement And Reduction Essay

Bio diesel is good for the economy because it is a fuel which can be created from locally available resources such as vegetable oils, coffee grounds, and animal fats. Biodiesel production and use

I believe this switch is vital to our future. With gasoline prices volatile and the Obama administration committed to easing the United States ' addiction to oil, many Americans seem to be taking more interest in pursuing alternative fuels. These alternative fuels include those derived from farm crops and other renewable organic sources. Among the most widely available are biodiesel and vegetable oil, both of which can be used to power a diesel engine.

[4] Biodiesel is another possible alternative. It can be produced from vegetable oils, animal fats, and recycled restaurant grease. Some of its advantages are that it is biodegradable, is generally safer to handle and it produces significantly less carbon dioxide emissions (up to 15% less). However, it too has problems. Similar to ethanol fuels, it has a lower energy content, which results in lesser MPG for cars. Fuels that contain a high percentage of biodiesel are also not

In today’s world there are many different engines that gets assembled in vehicles. The main difference in the engines are if they are gas or if they are diesel. While bearing some minor similarities, the differences between gas and diesel are remarkable.

Gasoline and diesel vehicles have been around for a long period of time ever since they were first designed around the 1930’s. The diesel market is in the middle of a revolution. Over the years that diesel has been around there are new enhancements that are increasing engine power and torque, lowering emissions and enhancing fuel economy, creating new and cleaner diesel vehicles. Through advancements in technology, gasoline and diesel powered vehicles have evolved since they were first designed to become more environmentally friendly.

Methanol as a biofuel is an environmental friendly substitute to pure diesel and can be obtained from biomasses. Use of biofuels such as methanol for combustion process is associated with positive environmental impacts. Using pure methanol or blended with diesel fuel in automotive has been proposed by researchers. In this paper, methanol was injected into combustion chamber of a ISM 370 HD diesel engine and exhaust emissions of this engine which took advantage of pure methanol were evaluated by using AVL FIRE CFD code software at four engine speeds (1200, 1400, 1600 and 1800 rpm). Additionally, influences of EGR mass fraction and various injection timings were investigated. For validation of simulation, in-cylinder mean pressure and rate of

Limited resources are available in the word. Transportation is very important element now days in the world. Trucks, public buses trains, planes and submarine are all a daily part of our lives. In the automobiles, buses, trucks, train commonly used gasoline fuel for transportation Gasoline is a refined product of petro diesel. Diesel fuel mainly used for heavy duty vehicles such as buses, trucks, train etc. Gasoline oil is the most hazardous fuel because it emits higher level of toxic gases in the atmosphere. Gasoline and diesel exhaust gases create negatively affect of air quality and damage the environment. These particular gases are not compatible with the respiratory systems and processes of life on Earth. Conventional petro diesel is limited resources available. . After sometimes fossil fuels are depict from the world. Thus alternative fuel is reducing the dependency of petro diesel

In spite of the fact that higher BSFC of n-butanol/diesel fuel the enhancement, oxygen content of the fuel blends gives higher BTE. The improvement in BTE can be referred to the enhanced oxygen content, which helps improvement in combustion, particularly during the diffusion combustion phase. Another influence factor that affects the BTE is cetane number. Lower cetane number of the BA-diesel fuel blends causes of the

The emissions from two stroke outdoor power equipment, light terrestrial vehicles, and marine vehicles are a significant detriment to air quality, human health, and the environment. Due to the mechanical nature two stroke engines operations, engines running on fuel oil mixtures that have been blended from biologically based oils generate far less Green House Gas emissions than two stroke engines running fuel oil mixtures blended from more traditional petroleum based outdoor power equipment oil. Preliminary results of previous research support the hypothesis that equipment running on bio-synthetic fuel-oil blends emits drastically lower amounts of Hydrocarbons, Nitrogen Oxides, and Carbon Monoxide than equipment operating exclusively on petroleum based fuel-oil mixtures. In addition, qualitative factors such as the color and smell of the exhaust fumes, and differences in engine performance have also been monitored and recorded. These data have been gathered in two separate and complimentary stages where the results were accumulated, condensed, and analyzed with the objective of discovering differences in the emissions and engine performance of Outdoor Two Stroke Power Equipment (OPE) running on petroleum based oil versus bio-synthetic oil.

This project will be developed to test the different performances of different types of fuel. The different types include bioethanol, kerosene, gasoline, and diesel. These fuels are used in everyday life to power different engines on different types of machinery.

Usage of diesel engine in automobiles is increasing worldwide because of its high fuel efficiency. As the usage increases, the emissions from the exhaust gases also increases which affects the atmosphere, thereby causing environmental issues such as global warming, smog and even acid rain. These emissions are mainly due to non-stoichiometric combustion, dissociation of Nitrogen and impurities in the fuel and air mixture. Major emissions include Oxides of Nitrogen, Oxides of Sulphur, unburnt Hydrocarbons, oxides of carbon and other carbon particles or soot. Significant measures are taken by the automotive industries for several years to reduces the intensity of these exhaust gases. There are two ways of reducing these exhaust gases are

Tables 1.4 and 1.5 present the detailed properties of biodiesel obtained by synthesis based on the starting oil, as well as a general guide to biodiesel properties with regard to the type of oil contained in chain departure [29]. Table 1.5 shows that it is advantageous to use an oil with short chain and saturated. Indeed, in this case only the calorific value is not favored. The five most common channels in vegetable oils chains are palmitic, stearic, oleic, linoleic and linolenic. As mentioned above, the FFA content influences the process and the final properties of biodiesel.

Significant energy demands related to population growth together with environmental concerns about the effects of fossil fuel usage (e.g., global warming) resulting in more stringent legislation for engine pollutant emissions have been attracting new interest in renewable, sustainable and environmentally friendly energy resources. Many ways have been applied or employed to reduce emissions levels as well as improve engine efficiency. Some fuels additive are being investigated and they have potential of emissions limited to, keeping the extra cost to the minimum as can possible. Alcohol biofuel such as ethanol, butanol are extensively investigated and commercially used. The experimental results revealed that significantly

Engine crankcase oils influence automotive fuel efficiency through the energy required to overcome viscous shear and boundary friction. Energy Conservation is an important performance feature of gasoline engine oils. Studies of power loss in internal combustion engines indicate that only 40% of the power developed by motor vehicles is available for useful work output and about a quarter of this work is consumed by friction losses. With half of these losses occurring in the piston assembly alone, the behavior of lubricants in this part of the engine are of particular importance. Past improvements in the lubricant-related fuel savings have principally derived from the development of the lower SAE viscosity grades. Fuel economy has linear relationship with
