Introduction The diesel engine dominates the field of commercial transportation and agricultural machinery on account of its superior fuel efficiency. However they emit more emissions. The use of oxygenated fuels seems to be a promising solution towards reducing emissions in existing and future diesel engines. Oxygenated fuel is a chemical compound containing oxygen. It is used to help fuel burn more efficiently and cut down on some types of atmospheric pollution. Oxygenated fuels are characterized by the following molecular conditions of the fuels: molecular weights are low and the molecules have high hydrogen to carbon ratios and a low number of carbon to carbon bonds which lower the formation of solid carbon particulates, molecules contain oxygen which suppress the formation of soot, molecular bonds break up to radicals at reasonable activation energy which leads to high cetane numbers. The oxygenated blends usually enhance the combustion efficiency, burn rates and the ability to burn more fuel and these blends offer the reduction of exhaust emissions. Oxygenate utilization to produce "cleaner burning" diesel fuels has been known for over fifty years. Oxygenates are well known to reduce particulate emissions. Low molecular weight alcohols, such as methanol, ethanol, and t-butyl alcohol, have been reported to reduce emissions. Higher alcohols, carbonates, diethers, such as diglyme, and various glycol ethers have also been reported. Particularly attractive are P-series glycol ethers, which contain both ether and a propylene glycol end-group. This paper deals with 2-Ethoxy Ethyl Acetate criterion and emmision reductions in modern diesel engine. Various application strategies to reduce emissions and enhance diesel fuel performance ... ... middle of paper ... ...ve on the Performance and Emission Characteristics of Diesel Engine”, National Conference on Recent Trends in Engineering & Technology, 13-14 May 2004.

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...
Hydrogen lies in one of the copious replacements for gasoline. It is not an energy source such as oil, but an energy carrier that is produced instead of digging and finding it underground. Though replacing fossil fuels by hydrogen fuel cell is very hard and costs a great deal, for the most part, hydrogen fuel cell is a zero carbon emission fuel which highly reduces the carbon emissions that causes pandemic global warming. Hydrogen is very helpful for nature by cause of replacing fossil fuels with hydrogen fuel cells might end global warming once and for all.
New vehicles can use this data to improve emission control and improve the vehicle’s efficiency. The Engine Control Unit (ECU) of the vehicle can adjust the concentration of fuel injected in to the engine to improve the type of burn. The ECU can be used to mai...
The Diesel engine, a compression ignition, internal combustion engine, was invented in 1893 by French inventor Rudolf Diesel. Diesel continued to developed his invention until 1897. “[his]... compression ignition engine could burn any fuel, the prototypes he built would run on peanut or vegetable oil–and needed no ignition system: It ignited by introducing fuel into a cylinder full of air that had been compressed to an extremely high pressure and was, therefore, extremely hot.” The Diesel engine impacted greatly on society in many ways, both good and bad.
The tradeoffs of using gasoline for cars are large emission of carbon dioxide and required large amount of chemical t...
On the whole, the purpose of the petrol and diesel engine are the same, to combust fuel
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).

Prior to 1978, both manufacturers and customers had paid little attention to quality of diesel. Later, they have been realizing the importance of quality. Under-quality products may cause customers to lose production time due to engine breakdown. They may also cause manufacturers to delay engine production and incur high cots in repairing. So quality will have more and more significant implications for future business of all manufacturers including Longxi.

With new diesel technology in today’s world, I think people should consider trying or using new diesel cars and trucks as well as the use of clean diesel.

Diesel engines are an important component of society in how they are used efficiently and effectively. Diesel engines have been around since 1892 when inventor Rudolph Diesel was able to achieve his goal of developing an internal combustion engine that can achieve maximum efficiency as seen in the Carnot Theorem. The Carnot Theorem set the standard for determining the maximum
Recent years have shown an increasingly large need for a practical renewable energy source for such reasons as diminishing fossil fuels and increases in greenhouse gasses. Hydrogen appears to be a way out of this gasoline-dug hole, or at least, a way out in the future. Hydrogen fuel cell cars are being engineered as we speak as the technologies to refuel them cleanly are being proposed. Unfortunately, most of the technologies associated with hydrogen are still in the prototype/pre-production stages and require better enhancements before becoming mainstream. This paper assesses the practicality of hydrogen power in cars both now and in the future while explicating the actual process of how a hydrogen fuel cell works.
Hydrogen would be one of the easiest sources of renewable energy to incorporate into our current energy infrastructure. Since hydrogen is a gas of normal temperature, it is possible to have it be used as a fuel in vehicles similar to current ones. For example, Hydrogen could be introduced into the vehicle as a gas, stored...
