I. INTRODUCTION A turbocharger is device as important part of all multicylinder diesel engines. Turbocharger is an exhaust gas driven induction device used in I.C. Engine to improve engine performance. This is done by forcing compressed air into the combustion chamber allowing more fuel to be burned resulting in a large air fuel ratio, large power & the method is called turbo charging. These devices use the energy of exhaust gases out from engine to run the turbine that in turns the air-compressor that provides. Now a day’s Waste gate operated turbocharger are also becoming popular now a days. Waste gate valve bypasses the flow that is coming from exhaust so that we can vary speed of turbine. It has certain effect of emissions that is being …show more content…
[1]Attention was paid to the exhaust emissions that is CO, HC and CO2.The engine was tested at three speeds within the entire load range. The results shows that the Wastegate TC is has less emissions than normal TC that is wastegate TC is advantageous at high loads at low and medium speeds. At rated speed, however, the Standard TC proved better than the WG one.[1]How Boost pressure influences the engine torque, power, and efficiency and exhaust emissions was studied by Sritharrajoo [3].Itmentioned that the incorporation of intercooler to the turbocharger system increases the performance even further. As per conclusion it is mentioned that addition of the turbocharger increased the maximum output of the engine and reduction in emission at the speeds above 2000rpm.Also HC and CO emissions are reduced when the engine is turbocharged compared to its stock naturally aspirated condition [3].The effects of turbocharger on the performance of a diesel engine using diesel fuel and biodiesel in terms of BP, torque, BSFC and thermal efficiency, as well as CO and NO emissions was also investigated[2] For this used biodiesel was rapeseed oil methyl ester, at full load condition at the speeds between 1200 and 2400 RPM. Emissions of CO in the operations with biodiesel were less than those in the operations with diesel fuel, whereas NO emission in biodiesel operation was found higher [2].Effects of different opening ranges of waste-gate on the exhaust soot emission of a turbo-charged DI diesel engine was investigated [5].How Waste-Gate Turbocharging Controlled in Automotive SI Engines and its Effect on Steady and Unsteady Turbine Performance is
"You can see that it is difficult to say which is better. The main advantages to supercharging are low-end response and simplicity. The main advantages to turbocharging are efficiency and the realization of maximum power. It is up to the vehicle owner to decide which solution is best for him or her" (Turbocharger or Supercharger).
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...
One main thing that people may be concerned about today when shopping for a vehicle is efficiency, people are always trying to find vehicles that provide the best fuel economy. What many people do not know are the advancements and environmental factors that diesel engines provide and protect. People are also unaware of the great mileage that these vehicles can provide. With the new ULSD and the new diesel engine technology, people can see mileage up to 58 MPG with a Volkswagen Jetta
Ideally an engine takes in Air (Oxygen and Nitrogen) and fuel (hydrocarbons) and produces CO2, H2O, and the N2 just passes through. However under normal driving conditions an engine will encounter lean conditions when cruising on the highway (better mileage) and rich conditions when accelerating (better power). The lean condition results in oxide and harmful nitrogen production. Rich conditions result in carbon monoxide production. For this reason catalytic converters are used on an engine’s exhaust.
BMW having high market share in European and U.S luxury car markets, started facing issues with launch product qualities and also facing a fierce competition from Japanese producers. Currently the market share was still stable but the rigorous growth of Japanese producers would affect BMW in future. These Japanese competitors had set higher standards of conformance.
The tradeoffs of using gasoline for cars are large emission of carbon dioxide and required large amount of chemical t...
When the Tesla Model S was first released, Consumer Reports named the Electric Vehicle (EV) the most remarkable auto ever tested. The consumer protection publication; that has been looking out for their readers since 1936; said that the Flagship vehicle from Elon Musk’s Motor Company, was essentially flawless. Its performance on the track and in safety testing was second to none. However, due to a drop in quality class; from average to below; the Tesla Model S has been removed from Consumer Reports’ Recommended List.
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).
The case revolves around Bob Marvin, president of the Motor Parts Corporation (MPC), and his executive vice president, AL Shepherd, who held a key senior management position in the company. After Bob, Al had the most important job since most of the line functions reported directly to him. His job required a considerable amount of traveling which he was not able to do lately because of his wife’s illness. Al 's wife, Ruth, was suffering from a malignant brain tumor due to which he was spending more and more time away from work to be with her.
The business world is becoming more and more heated up as a result of the ever increasing levels of competition. Each and every industry is witnessing an alarming rate in the number of competitors that exist within it. This is further fueled by the increasing world population, which brings about the speculations that the future of the market is rather bright. It is interesting as to how many things are nowadays done based on speculations and future expectations. In the turmoil of it all, marketing has been established as a very effective tool used by various firms to gain competitive advantage over others. As such, each organization has been able to develop its own marketing strategy based on the various things that affect the industry and the nature of business undertaken. Theories and practical research are two major items that form the basis of development of marketing strategies. Rolls-Royce is one of the many organizations that have been in big business for a long time. As such, the company has been able to identify major areas of strength and weakness when it comes to marketing.
Portfolio Project: Tesla Motors Case Study Tesla Motors (Tesla), founded in 2003 by Elon Musk, is an automotive company focused on enhancing Electric Vehicle market by creating optimum performance, all electric, vehicles for every class of consumer (Tesla Motors, 2015). In order to achieve such ambitious goals, Tesla Motors not only designs, but also manufactures, and personally sells the company’s electric vehicles (Hirsch, 2015). As additional quality assurance, Tesla Motors also designs, manufactures, and sells, electric vehicle power-train components, and battery products (Hirsch, 2015). Yet, despite the pivotal role Tesla’s self curated products play in the success of Tesla’s vehicles, the socially responsible company does not privatize Apart from Musk’s concise vision statement Tesla has a truly inspiring mission statement, “At the core, Tesla Motors believes that electric cars should not be perceived as a sacrificial mode of transportation. Tesla Motors has brought the best of both the automotive and technological worlds together by permanently etching the image of electric cars being a step backwards in performance, efficiency, and design” (Tesla Motors, Chiefly, and most apparently, it is the goal of Tesla Motor to generate demand for Tesla vehicles (Andrade, Holloway, Payne, Roy & Sheffield, 2015).
Hunsk Engines is a motorcycle company that made the fatal mistake of expanding its research in the market on its new products. The companies main competitors were companies like Harley Davidson, where they sold classic products that were seen as something with altering respect. Marty Echt is hired on by Hunsk Engines to restore the company’s image, on what used to be classic motorcycles. He argues that the company made the mistake of forgetting about its original products and, “lost its identity”. This problem frequently happens when companies attempt to grow, in order for new products to make it in the market place you have to carefully strategize its competitive characteristics and know when to introduce a new product through Michael Porters life cycle.
Most people today fill up their car with different qualities of petrol, because that's what the average car takes. They don't usually consider an alternative for the petrol that they load into their cars. Although petrol is widely used, it is not the only source for a car to get its power from; diesel and electricity are alternatives to the general petrol used by most cars. Although different from each other, diesel and electricity are alternatives to the average gasoline received at a gas station. Diesel is a more concentrated type of fuel that is usually used by big automobiles because they require a lot of power in a little amount of time. Electricity is a method that uses the power of batteries to produce a low horsepower but, nevertheless fast automobile. Electric cars are generally created to be soundless and environment friendly. The purpose of this paper is to classify and educate the reader of the different types of fuel available for an automobile to use: petrol, diesel, and electricity. The general petrol, used by most people, is usually the only type of fuel accepted on the average car in the United States today.
...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.
China is a strategically important market for Burger Fuel as it has all the ingredients which Burger Fuel wants in its target markets. The main competitors of foreign players for Burger fuel are Mc Donalds, Burger King, KFC are intense and it should be compete with them. It means the more opportunities are creating in china for the Quick service restaurant that will be expanded. Such situation is better as it encourages continuous innovation. The targeted market of China economy is highly emerging now which also control the world 's economy now. It has not so long history to open China market for the foreigner. Currently, the market penetration of fast food are very low which is about 8.7% of chicken fast food and 3.1% of
