A water-in-Diesel emulsified fuel was investigated on a 6 cylinder Diesel engine to the influence of water emulsification on the engine performance and exhaust gas emissions. The existance of water Particles in the way of emulsification method in diesel fuels makes microexplosion phenomenon during combustion in the cylinder. With incidence of this process, more oxygen offer to the fuel and make it to be improved combustion.
Emulsified Diesel fuels by 5, 10 and 15% water/Diesel ratios by volume, were utilized in a 6 cylinder, direct injection Diesel engine. Fuel usage of the emulsion systems was more than that of diesel, but the tiny droplets of water improved diesel combustion. Compared with diesel, a reduction in carbon monoxide (CO) and nitrogen oxide (NOx) emissions and a slight reduction in HC was observed for emolsified fuel. The existance of water particles and additives in the fuel decreased the heating value of the fuel, and despite the improvement of combustion as a result of microexplosion phenomena, was made a loss of engine power.

Introduction
Diesel engines have been utilized in heavy duty vehicles for a ahead of time; it's just in the past decade that it has become popular in light duty application for their higher fuel efficiency. Higher fuel efficiency in the diesel engine is obtained as a result of high compression ratios along with high air concentration in the combustion chamber. Nevertheless, these same factors results in large NOx emission in diesel engine. The stringent emission norms have been a significant driving force to enlarge the internal combustion engines more environment friendly. The important emissions from diesel engin...

...gital flowmeter was used. This flowmeter was placed in the fuel flow path and fuel back path to the other tank redirected. Emission analyzer made by Germany was used for measuring the outflow pollutants from the exhaust that having a measurement capability of O2, HC, NOx, CO, CO2 and represents the oil temperature. The water-in-diesel emulsions consisting of Diesel fuel and ordinary tap water, were prepared in an ultrasonic vibrator. To stabilize the emulsions, a 2% by volume surfactant mixture consisting of Span 80 and Tween 80 was used. Four blends were tested: pure Diesel and Diesel fuel with surfactant and 5%, 10% and 15% water by volume. The prepared emulsion fuel is a milky white liquid that is observed in Fig 6. For each run the engine was started on pure Diesel and then switched to the test blend. A schematic picture of experimental set-up is given in Fig 7.

Here's 8 Questions to Ask Before Enrolling into a Diesel Mechanic School. 1. What is the difference between a. and a. Has the school been assessed by NATEF (which remains with the National Automotive Technicians Education Foundation)? Note: When I say NATEF realize that their essential concern is to enhance the nature of auto expert preparation programs all through the U.S. by means of deliberate confirmation accreditation. NATEF is run by a 14-member trustee board that is selected by the ASE Board.

Have you ever wondered how those big heavy construction equipment are able to work day in and day out and able to go through so much work? Well that’s because of their mechanics like me and I’m going to show you what they do day in and day out to keep them going. Thesis Statement: The career of diesel mechanic is challenging, because of everyday is something new and anything can happen. The research will describe the career of diesel mechanic, what is required to become a successful, and the impact this career has on society.
Diesel mechanics are practically the backbone of this country. Everyone knows that things are delivered via eighteen wheelers these days occasionally they need to be repaired and have maintenance done to them. When that happens who’s there to save the day? DIESEL MECHANICS that’s who! You’re about to learn what it takes to become a diesel mechanic and what you’ll make when you are one.
Fig. 2(A) shows the phase diagrams of IPM, water, and surfactant mixtures at the ratios of 60:40, 65:35, and 70:30 (v/v), respectively. Fig. 2(B) shows the phase diagrams of ethyl oleate, water, and surfactant mixtures at ratios of 90:10, 95:5 and 100:0, respectively. Filled circles mean self-emulsifying points, and black areas represent the self-emulsifying regions. In other area, the compositions showed inverted emulsion, gel-like form, or phase-separation. In general, when the oil content in the oil and surfactant mixtures is ≤30%, the condition of the mixtures changed from water-in-oil emulsion to a clear gel-like form and then to microemulsion. Otherwise, the dispersions showed phase separation, this result was similar to the results previously studied by Guo et al. [16]. Our finding showed that IPM + surfactant mixture (65:35, v/v) and ethyl oleate + surfactant mixture (90:10, v/v) showed the most self-emulsifying regions (Fig. 2). Overall, in contrast to IPM + surfactant mixture (65:35, v/v), ethyl oleate + surfactant mixture (90:10, v/v) showed finer emulsion in larger self-emulsifying range. These results indicate that ethyl oleate and Tween 80:Carbitol (90:10, v/v) were identified as the optimal oil
The purpose of this lab was to investigate which additive(s) will create the longest lasting oil-in-water emulsion.
Driven in large part by global initiatives and the potential for stringent regulations, the past decade or two has seen a marked increase in the importance of improvements with respect to environmental standards, including emissions and increases in fuel economy. In 2002, Cummins Emissions Solutions was launched after the need was identified for an emission solution that would help engines meet future regulations. In 2006, Cummins pioneered a hybrid diesel-electric bus which reduced fuel consumption and greenhouse gasses by more than 30 percent and me...
The diesel engines combustion process is a little different than the typical gasoline engine. A couple main things that diesel engines have that gasoline engines do not are, carburetors and spark plugs. Unlike a gasoline engine, air is first allowed into the cylinder rather than a fuel and air mixture. Once the air is compressed it creates a source of heat, then a mist of fuel is injected to start the combustion process which then creates the energy. Since diesel engines do not have spark plugs they are able to take in larger amount of fuel, this obviously means there will be more power and will guarantee better efficiency. Another thing that is very important is that diesel tends to be a better lubricant than gasoline, being that it is a better lubricant there will be less friction which will generally increase the life of the engine (Woodford). Diesel engines operate at slower speeds than gasoline engines, therefore diesel engines tend to have longer lifespans than gasoline
Diesel Mechanics is a good field to to study and go into. The reason being is because everything you do or everything you buy or even get delivered to your house has something to do with diesel. Diesel trucks like tractor trailers are one of the main delivery systems in the world so someone has to know how to work on that if one of those trucks breaks down. Even though diesel motors are not as popular right now they are coming up fast and more and more people are wanting these kinds of trucks. Which means that diesel mechanics has a bright future in making more money and becoming more popular. By the year 2020 most cars in America and the world will be diesel which means more job opportunity and more money.
The main emmissions of a car engine are nitrogen gas, carbon dioxide, and water vapor.
85% equipments use single-cylinder diesel engines, while the rest use multi-cylinder ones. In the market of multi-cylinder diesel the competition is less intense because of excessive demand. The prospect is much more promising. Longxi has a certain competitive advantage in this market, resulting from its popular product such as SL2100.
Many years ago, engineers realized that in high heat petroleum-based oils break down and lose their lubricating capabilities. Over time, petroleum–based oils also begin to oxidize and create sludge, leaving damaging residue inside the engines. This problem led Dr. Hermann Zorn (German) to develop Synthetic Oil for high-temperature use in jet aircraft engines. To overcome the breaking down problem of petroleum-based oils, synthetic oil is formulated in laboratory and doesn't contain the naturally occurring chemicals that break down at high temperatures. Furthermore, Synthetic oil is manufactured without many of the chemical compositions that contribute to oil oxidation and sludge buildup. Synthetic oil tolerate the temperatures at which petroleum-based oils would burn up. Synthetic oil is not distilled from crude oil. It is made through a chemical process known as the Fischer-Tropsch process. It goes through many chemical reactions which uses methane, carbon monoxide, and carbon dioxide as the raw materials. Synthetic oil not only work best in heat but also provide various benefits in extreme cold. Petroleum-based motor oil gets thick in low temperatures as a result it requires the starter and battery to work harder ...
Diesel engines are a marvel of the world and have been since creation in 1892. Today there are several types of these engines including, two-stroke and four-stroke engines as well as the idea of how diesel engines operate. The diesel engine is a necessary component of the shipping industry as well as the daily lives of people.
Bad gas prices are causing more car companies to make more hybrid cars to save people money in the long run. Not all diesels are gas guzzlers. Most of the new diesel trucks get a lot better gas mileage now than they did ten years or so ago. Volkswagen is now beginning to make this new car that has a Turbo Diesel Injection Clean Diesel motor in it. Unlike old diesel engines, this one is more modern to get better gas mileage and be cleaner to the environment. This new car that they have invented gets much better gas mileage than the older diesel engines that were in old trucks and cars.
