Stringent diesel emissions regulations around the world have put much pressure on the shoulders of manufactures to reduce the level of emissions entering the atmosphere from diesel engines. Much of the initial attempt to achieve this by the manufactures was by the substitution of biodiesel in place of the conventional petroleum diesel. In order to create a balance between the vehicle performance and the imposed emissions regulations, many manufacturers prefer to blend petroleum diesel with biodiesel in a proportion which is deemed suitable to run on their engines.
In a statement from the diesel fuel injection systems manufacturer’s association, they suggested that diesel fuel specification should be updated on a regular basis, to allow for the gradually increasing percentage of biodiesel. By so doing injection components could be manufactured such that they are protected from the possible secondary effect of the fatty acid methylesthers, which includes filter plugging due to softening and corrosion of zinc or aluminium parts in the fuel injection system due to the presence of free menthol residues.
Whilst biodiesel has been highlighted as a plausible substitute for petroleum diesel, great concerns still arise over the effects of its emissions on health and environment, considering the fact that only a few of its hydrocarbon emissions are yet known. Studies about the effects of increasing biodiesel blend ratio on the operation and emissions of diesel engines have been documented in a vast amount of published and unpublished literature since the 1980’s (1), (2), (3). A general trend of observation amongst most of the literatures reviewed is a reduction in CO and THC emissions with increasing biodiesel blend ratio, like wise incre...

...ation of after treatment systems have been proposed by some researches, as a viable solution in reducing CO, THC and NOx emissions to a non-harmful level. Some of these proposed after treatment systems include DPF (Diesel particulate filter) and DOC (Diesel Oxidation Catalyst). Amy et al’s (27) research in to effect of biodiesel emissions on the performance of a diesel particulate filter in a diesel engine, showed that increased biodiesel blend ratio produced less soot and thus required a lesser regenerative temperature, when compared to the conventional petroleum diesel. Their conclusions indicated the fact that with biodiesel fuels, the regeneration of particulate filters could be carried out without the fear of causing an over heat in the exhaust system. They applauded the reactive nature of the biodiesel soot, as a major contributor to this trend.
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.
When I get out of high school I want to be a diesel mechanic. A diesel mechanic works on diesel engines, they repair and maintain diesel trucks/automobiles and make sure everything is working right. There are multiple kinds of diesel mechanics such as, Aircraft and Avionics Equipment, Mechanics and Technicians, Heavy Vehicle and Mobile Equipment Service Technicians, and small engine mechanics.
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...
In the future the automotive industries will need alternative fuel sources, in turn that means they will need alternative engines in their automobiles. The engines found in their cars will have to be changed to fit the new fuels being made. They have many directions in which they can go concerning engine types and fuel types.
In the United States we have been looking into alternative energies to reduce our dependence on oil and help reduce our carbon footprint. One method the EPA has come out in support of is ethanol production. Ethanol is considered a green fuel because it recycles the burned carbon each time new crops are grown. In theory ethanol is a good stepping stone between using gasoline and zero emission power sources. However biofuels are still young technology that has many problems before it can be useful. The EPA is in full support of biofuels and has mandated that by 2020, 36 billion gallons of biofuels are to be produced in America. Currently almost all of America biofuels comes in the form of corn based ethanol which is extremely inefficient and can cause sustainability problems. Due to this reason only 15 billion gallons of the mandated biofuels can be form corn based ethanol. The rest of the biofuel must come from non-corn based alternatives such as cellulosic ethanol which the EPA projects to create all most all of the 21 billion remaining gallons of ethanol. Cellulosic ethanol uses the cellulose that is in all plants matter to create ethanol. Cellulosic ethanol is far more efficient than corn ethanol because you can use the whole plant and it sets no limitation on what type of plant matter can be used. Even though the EPA projects that these number will be achievable, due to current setbacks and efficiencies cellulosic ethanol will not be able to meet this output within the time constraints and a goal of 2034 years would be more realistic in the long run.
Diesel Mechanics and Auto Mechanics share both similarities and differences when it comes to their duties and responsibilities. The similarities can include the responsibility of staying up to date on the latest technology used in both diesel and regular gas powered vehicles. Plus fixing, repairing, and inspecting either type of engine by making sure the vehicles engine is working properly. The differences can include the duties of fixing only diesel powered engines to fixing things that do not have diesel powered engines. Also one works on small cars and trucks, while one works on big trucks, boats, buses, and construction equipment, such as bulldozers, and excavators. The career paths of Diesel Mechanics and Auto Mechanics also have both similarities and differences in terms of the duties involved, the rewards, and challenges.

When the problems with gasoline use are considered, the catastrophic environmental effects are the primary concern. Automobile use consumes 70 percent of the United States oil supply and is responsible for one-third of the nation’s carbon emissions (Lovins 173). This results in pollution, global warming, and health problems for the people, plants, and animals. The search for alternative fuel is powered by the increasingly evident environmental problems and long-term health of the planet (Povey 17). Fortunately, reducing emissions globally is predicted to have a positive effect and offset previous harms (Backer).
The ecologists are of the opinion that the racing industry is an unnecessary burden for the society, that it does not serve any purpose. But the fact is that the racing industry is just like any other industry that is driven by diesel fuels like car manufacturing and airplane development. If these two consumer goods are considered an important part of human technological innovation, there is no need to sideline the racing industry. On the basis of this, we can also say that using biofuels for racing is preposterous because the biofuels cannot give the thrust that the racing cars need in order to compete. Biofuels are not of high-octane in nature; diesel fuels are. Biofuel cannot be characterized as an energy rich fuel. Using biofuel instead of diesel fuel will negatively impact the performance of racing cars, leading to heavy losses for the racing industry (The Royal Society 08).
After Diesel’s death, the diesel engine underwent much development and became a very important replacement for the steam piston engine in many applications. Because the diesel engine required heavier, more robust construction than a gasoline engine, it was not widely used in aviation. The diesel engine became widespread in many other applications, however, such as a stationary engines, submarines, ships, and much later, locomotives, trucks, and in modern automobiles. Diesel engines are most often found in applications where a high torque requirements and low RPM requirements exist.
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.
The diesel we use today is much “cleaner” than previous types. Clean diesel is a type of diesel fuel that is often referred to as ULSD. This acronym stands for Ultra Low Sulfur Diesel. This type of fuel is a more refined fuel than previous standard types of diesel. Although it is not the same as biodiesel, many people do not actually know the difference between “biodiesel” and “clean diesel”. Biodiesel is a fuel derived from biological substances which can include plants, plant oil, and animal fat. Even though biodiesel and clean diesel are two different things, they are usually mixed
...ch is used to replace natural gas. He also stated that, among the equipment used to burn the biofuel, the suspension burner have the ability to exceed 99% efficiency and whole-tree burner can reduce the cost of harvesting and handling woody fuels by about 35% (Brown, 2003). Moreover, the usage of bio-energy in long term is to provide a degree of ecological balance and climate change, avoid acid rain, reduce soil erosion and minimize water pollution (Gevorkian, 2007). Therefore, biomass is environmental friendly like solar energy. Based on the research that has been carried out regarding the synthesis of gas from biomass, the gas gasifies in the internal combustion engine. The relative energy density of synthesis gas is higher than the fossil fuel under certain conditions. In addition, the relative flame speed of synthesis gas can reduce the time for spark ignition.
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.
