Environmental And Social Impacts Of New And Remanufactured Diesel Engines

In 2002 a joint project between International Navistar and the Ford Motor Company was born. “The goal of this project was to create an engine that was fuel efficient, emission compliant and would be able to outperform all of the competition” (Banks Power). With over 2 million ford super duty’s equipped with the 7.3l Powerstroke engine on the road, the new engine would have big shoes to fill. The engine that was to replace the outdated, underpowered and overall inadequate 7.3l Powerstroke was the International Navistar 6.0l turbo diesel.

Diesel is the fuel of choice in the European automotive market, due to the fact that it provides high-torque, efficient alternative to gasoline. The American view of diesel, however, is much less positive overall – most Americans remember the noisy, smoky diesels of decades past and know little about the quiet, clean diesels of the present. One of the best arguments for the switch to diesel fuel in the United States is that a fueling infrastructure is already in place, as transportation companies rely on diesel fuel to distribute goods across the United States (Is Diesel). This would negate the need to construct an entirely new infrastructure, which could cost hundreds of billions of dollars. Diesel is also considerably more environmentally friendly than gasoline, due to the fact that it is less refined (a process which uses large amounts of energy) and that it is more efficient than gasoline (ACEA). The combustion process in a diesel engine, which exerts high pressure on the fuel to ignite it, is the source of the motor’s increased

“The US auto industry directly employs 1.55 million Americans and impacting a total of 7.25 million US jobs, generates $500 billion in annual compensation.” (1) With such a large industry looming in the economy, it is inevitable that it will face environmental challenges. Environmental challenges can be hard to control and are essential to the success of a company. The challenges that the auto industry must contend with are many and complex, such as; global competition, consumer opinions, and new technology, a difficult fight lies ahead.

In 2011, Volkswagen was the world’s largest automaker, with brands from Audi to VW to Porsche. Volkswagen was the proud marketer of “clean diesel” cars. But the company, starting in

Whenever people think of diesel engines, they imagine black soot pouring out of a big rig on the interstate. While that has been correct in the past, the technology is arriving that changes people’s thoughts to that of a more ecologically friendly. Ever since Rudolf Diesel created the diesel engine, it has been written off as a smelly, inefficient, and dirty way of converting fossil fuels into power. Diesel noticed how the steam engines of the times were wasting 80-90% of the fuel they burn, making them very inefficient. After learning about how inefficient typical gas or steam engines were, he dedicated himself to create a clean burning engine. In the beginning, the stereotypes were completely accurate, but those same adjectives are simply incorrect in today’s times. These constant put downs by environmentalist are often uneducated and generalized by the small number of older, inefficient trucks that are still on the road. The modern diesel engine is an absolute marvel when it comes to the fuel efficiency, power output and societal benefits. While the light duty diesel pickup may be loud and intimidating, the benefits they provide society are vastly underappreciated and need to be more thoroughly recognized.

In the automotive world, efficiency and power are two elements of vehicle performance metrics that while important to many consumers and critics alike, appear to be elusive when in convolution with one another. In automotive history, good fuel efficiency equaled compromises in power and performance and vehicles with large displacements and torque usually had worse gas mileage. The exception to this rule were diesel engines, which managed to combine better efficiency than many four-cylinder gas engines while providing very high torque number for better performance. The main drawback that diesel’s faced was due to their stigma of being dirty, as they emitted more greenhouse gases including nitrous and sulfur oxides. Coupled with the stricter emissions that many states began to implement, primarily overseen by the EPA, it became harder for car manufactures to certify diesel engines for emissions while maintaining high fuel economy and power output figures. The emission control hardware and software in diesel vehicles also came at a high price and with increased complexity, both unwelcoming additions for any car company wanting to mainstream diesel’s.

The company has been facing several challenges recently which include the production of automotive machinery that have transmission problems whose impact has been proved to be a big problem. Pollution of the environment is another great challenge facing the company which comes both from the production mechanisms applied by the company and transmission problems of the vehicles which are released into the atmosphere greenhouse gasses. This fact places the company in a state that does not meet all the requirements of environmental sustainability. The project mainly aims at conducting an assessment of the corporation manufacturing techniques and all the necessary improvements needed to significantly reduce the levels of pollution. Implementation of innovative techniques of production, recycling of materials in production and designing cars together with machines

It has been proven that the diesel engine produces more power with fuel efficiency “Diesel fuel has the advantage when it comes to fuel economy, as there is more energy in a gallon of diesel fuel than a gallon of gasoline. In other words, a diesel engine can make more power with less fuel than a gasoline engine” (Hollis). However, Tom Venetis states that “ diesel, once the cheaper fuel for many years, now is the most expensive than gasoline per equivalent liter.” In fact, diesel engines are more commonly used in the work field because of their endurance and fuel

* Diesel engines get better mileage than gasoline engines for two reasons: diesel fuel contains more energy than gasoline, and a diesel engine injects fuel and air into a combustion chamber at a much higher rate of compression, which makes the fuel burn more efficiently than fuel in a gasoline engine.

Thesis Statement: The strain on the diesel supply in America is too high and a stable source must be

There are more than one billion cars around the world up to date and this number is increasing rapidly because of the demand for them. Most of the cars in the world have big engines right now. Big engines are made of eight cylinder (V8), ten cylinder (V10), or twelve cylinder (V12 / W12). Those types of engines have been used for many years in the car industry. Most of the car manufacturers prefer to use those engines because their customers like them and thinking that more cylinder means more power. For many years, those car manufacturers have not realized one thing that big engines emission rates are actually really important for the environment

The topic of vehicle emissions is always being discussed by people of all different fields. Engineers look at the problem as “How can we design vehicles to be more fuel efficient?”. On the other hand, environmentalist look at the problem as “How can we stop this?”. Authors Khan, ABM S; Clark, Nigel N; Gautam, Mridul; Wayne, W Scott; Thompson, Gregory J and Lyons, Donald W from the Department of Mechanical and Aerospace Engineering at West Virginia University in Morgantown have written an article for the “Journal of the Air & Waste Management Association” on the topic of vehicle emissions. The article is titled Idle emissions from medium heavy-duty diesel and gasoline trucks, the most of the contents of the article are results from an

Because many great innovations are being employed in the engine design such as: direct air intake, sequential variable compression ratio, super mixing process, constant volume combustion, controllable combustion time, high working temperature of the burner, high expansion ratio and self adapting sealing system etc., the thermal efficiency of the engine could be potentially as high as 65 %, even more if water add-in technology is to be

due to pre-mixing of fuel and air the petrol engine operates at higher speed than diesel,

In the automotive industry, there are drastic improvements and innovations in vehicular technology. These advancements are bred by research about our world and society, helping us understand how to revolutionize technology so that they can work as efficiently as possible. With the increase in knowledge, society has become more aware of the carbon footprint that they leave on the environment. In an effort to improve the
