Reduction Of Carbon Diesel Engines And Catalytic Converter

After many years of trial and error, a combination of inventors and engineers developed a practical, effective internal combustion engine that greatly affected the world. This paper will give opposing views on the background and analyze the effects it had on transportation and the environment.

To stop the pollutants from entering the atmosphere car manufacturers have fitted these cars with extremely effective filters but the issue with that is people tamper with them. So when a diesel can emits a dark black smoke it is most likely because the filter is broken or it's missing altogether. A down side to the filter is that it works best when it is hot so short trips around the city won’t do anything to the NOx that passes through it. Car manufacturers have been finding other ways to reduce the emissions by recirculating it back from the exhaust to the cylinder. Another thing they have been doing is injecting urea which is made of ammonia to trap the

Central Idea Statement: There has been three major technologies added to diesel exhaust systems since 2003 including an EGR, DPF, and SCR that have dramatically reduced NOx emissions (smog gases).

In 1859, the first oil well was dug, however, the gasoline had no use until the invention of the automobile (EIA, 2014). Nowadays, gasoline is classified as a refinery product and is produced as three types: Unleaded Regular, Premium and Super-Premium (Gary, J. et al, 2007). The first one is most common between automobiles, it is a byproduct of crude oil with an 87 octane rating and a highly flammable material. It is also environmentally-friendly and has less hazardous to health due to no lead compounds. Premium Gasoline is less polluted due to its detergent additives that make engines cleaner. It shares similar characteristics

Chapter 6, “The Burden of History: Expectations Past and Imperfect” from Kirsch’s book, The Electric Vehicle and the Burden of History, focuses on the problem of automobiles in the modern day. Kirsch states that internal combustion engines release greenhouse gasses, which harm the environment. Each individual contributes to air pollution

With the supply of fossil fuels steadily declining, gas and oil is becoming harder to harvest which means it is getting more expensive. Fossil fuels take millions of years to be naturally produced, yet each person burns gallons of gas per day (Maehlum par. 5). Though fossil fuels are produced naturally, when burned they release nitrogen oxides gases into the atmosphere, which contributes to the formation of smog and acid rain. According to the EPA, major sources of these nitrogen oxide emissions come from cars and trucks, coal-fire powered plants, large industrial operations, and ships and airplanes (EPA par 3). By reducing the number of gas powered cars on the road, we can reduce the amount of harmful chemicals we are releasing into our atmosphere.

As a result of EPA regulations, today’s diesel engines are more efficient than ever before seen in large and midsized trucks. Certain regulations restrict truck owners from using certain truck models, because of excess diesel emission. Increasing drastically as technology improves, cars and trucks produce less and less diesel exhausts and emissions. “But because diesel engines can operate for 30 years or more, millions of older, dirtier engines are still in use,” (Epa.Gov). Reducing exposure to diesel exhaust from these engines is especially important for the preservation of human health and the environment. According to the EPA, the United States Environmental Protection Agency,

We have developed a process that has been successful in improving fuel economy and engine life while simultaneously reducing harmful emissions output.

Environmental concerns have been raised from time to time because of the dependency on the gasoline-fueled engine as the chief auto powertrain technology. This has resulted in exposing many automobile users to unpredictable prices of fuel. These issues were, however, the reason for

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.

The growing dependence of many countries, especially the USA and Europe on the imported oil and the daily increase of oil price and the heightened concern on the global warming and the environmental pollutions which has forced many car manufacturing companies to study the new and innovative techniques in solving this very important issue.

The world we live in is surrounded by diesel engines. They are on the freeways, railways, airways, and are one of the leading electricity producers in the world. They are also becoming more popular in automobiles. These engines are efficient and reliable and they are getting very sophisticated. However, the physics behind these engines has not changed.

Since the development of the steam engine people had been interested in creating self-powered vehicles, this manifested during the industrial revolution as the train. However, as time went on people became interested in creating a vehicle that wasn’t confined to tracks. The earliest attempts were moderately successful but served little practical purpose. Automobiles first began to truly spread with the invention of the electric motor which created cheaper, more powerful, and safer automobiles. Still the automobile still had numerous problems and were mainly in the hands of the rich. It was the development of the internal combustion engine and the assembly line that was truly able to create a practical vehicle that could be used by all and

A way to approach the elimination of carbon monoxide from car exhaust is through the use of organometallic catalysts. Through the use of a catalyst, a reaction can occur at a faster rate and at lower activation energy. Said catalysts serve are of great commercial interest because they essentially convert simple mole-cules into more complex ones.6 Unlike homogeneous catalysts, heterogeneous catalysts are not in the same phase as how the reac-tion is occurring. Because of this, the catalysts are considered to be cheaper and easier to obtain. It is also considered more envi-ronmentally friendly to use.6-7

Road transportation providers have adopted several innovations that have lowered the environmental impact of this transportation mode. The adoption of clean diesel technology by the industry has resulted in significant reductions in fuel use and emissions by trucks. This innovation in diesel engine
