Turbulence Modeling Of Vehicle 's Exhaust System

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 The engine that was to replace the outdated, underpowered and overall inadequate 7.3l Powerstroke was the International Navistar 6.0l turbo diesel.

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.

Exhaust manifold is a part of diesel engines and is required to collect the exhaust gases from the cylinder head and send it to the exhaust system. This is found in between the engine and exhaust system. Exhaust manifold plays an important role in the performance of automobile. Particularly, the efficiencies of emission and the fuel consumption are nearly related to the exhaust manifold. The manifold may be a casting or made of relatively light material depends on working environment. The purpose of the exhaust manifold is to collect and carry these exhaust gases away from the engine cylinders with a minimum of back pressure, without affecting engine performance.

Automobile designers and major leading automobile companies are researching trying to find the answer to creating the best automobile possible. Factors surrounding this problem include improving fuel efficiency, aerodynamics, speed, and creating a futuristic design. Students should get involved in Co2 drag race for lots of reasons. A few of those reasons are that students should go out and have fun dragster racing and it is also a nice break from textbooks. Co2 drag racing will also teach them skills such as building dragster cars, teamwork, go through challenges, and intelligence.

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

The expertise used to test automobiles could not fully and accurately describe the limitations of driving. Real driving is much more hostile and wide-ranging than analysis technologies could then excuse for always. The tests must measure exhaust emissions in a strong and repeatable method. While the tools we use for testing have developing immensely over the years, the challenge to be ever more self-motivated and precise still remains.

Cristina the RT placed patient on transport vent. RN left with the patient while Cristina pushed the 840 vent. RN reported that the patient began Brady and desaturating she started bagging the patient. RT called to the bedside IR and RT made sure vent was functioning correctly. High peak alarm was displayed. Patient’s procedure was cancelled and the patient returned to bedside. Clinical specialist Raven and Manager Laura notified transport vent was taken to out of service sent to BIOMED. Breina ran a service check in which found that the high pressure alarm was malfunctioning. Brena communicated via email and verbal with Risk, director of respiratory to inform them of the situation. Transport Vent sent to company for service.

Three main areas Computational Fluid Dynamics, Alternative engines and advanced materials are considered in research.

The same principle that allows an airplane to rise off the ground by creating lift from its wings is used in reverse to apply force that presses the race car against the surface of the track. This effect is referred to as "aerodynamic grip" and is distinguished from "mechanical grip," which is a function of the car mass repartition, tires and suspension. The creation of downforce by passive devices almost always can only be achieved at the cost of increased aerodynamic drag (or friction), and the optimum setup is almost always a compromise between the two. The aerodynamic setup for a car can vary considerably between race tracks, depending on the length of the straights and the types of corners; some drivers also make different choices on setup.

When a body moves with high velocity at that moment aerodynamics forces such as drag, lift (or down force) are the primary concern that are caused by the airflow over the body. In engineering aerodynamics principles are applied in every kind of design or structures such as automobiles, aeroplanes, tall buildings and bridges. However, largely the aerodynamics principles are applied on aeroplanes and automobiles. This project involves the influence of aerodynamics principles over the rear wing of a Subaru Sports Sedan race car.

Electric cars are becoming very popular in today’s world and are becoming more main stream. One reason for this is the need for automobiles that have a lower or a zero carbon footprint. For the majority of the history of the automobile, the propulsion system was a gas or a diesel engine that would run off of fossil fuels. The burning of fossil fuels is very hazardous to our world and also creates much toxic pollution. However, electric cars run off of electricity, which is a very clean and pollution free resource, depending on how the electricity was produced of course. In this paper we are going to examine the history of electric cars, look into modern electric car technology, and peer into the future of electric car technology to see if EVs might be the answer to dramatically reducing our global pollution.

CE1.3] Baja SAE is an intercollegiate engineering design competition for undergraduate and graduate engineering students. The object of the competition is to simulate real-world engineering design projects and their related challenges. Each team is competing to have its design accepted for manufacture by a fictitious firm. The students must function as a team to design, build, test, promote and build a vehicle within the limits of the rules, also to generate financial support for their project and manage their educational

The findings indicated manufacturing combustion engines use gasoline contributes toward Warming Climate Change. The major problem with cars and trucks plays important role in our society transport infrastructure is contributor to Air Pollution. These machinery that uses combustion engines burn gasoline or other fossil release polluted chemical. The major contamination pollutants are carbon monoxide, hydro-carbons, nitrous oxides, carbon dioxide. The environmental understanding the ten vehicles selected contributed toward emitted directly into the atmosphere when the carbon in fuel doesn 't burn completely. There is aftermath a secondary pollution after contamination has been released into atmosphere. The combination of various types of air pollution combines in sunlight. Result in holes ozone in the atmosphere ozone protects us from the sun’s ultraviolet rays which causes cancer. Hazard gases cause’s holes in the atmosphere’s ozone layer allow ozone to come closer to earth. Motor vehicle importance contributes towards smog accumulation causes serious respiratory illness. The number of vehicles in operation worldwide surpassed the 1 billion-unit mark in 2010 for the first time ever (Greenhouse). According to Ward’s research, which looked at government-reported registrations and historical vehicle-population trends, global

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.

In the world, pollution from automobiles are among the greatest pollutions to the environment. Exhaust fumes coming from a vehicle 's engine not only pollute the air with harmful substances that all living creature, like us inhale. But it is also seen as the leading cause to
