Advantages And Disadvantages Of A Green Engine

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 The engine that was to replace the outdated, underpowered and overall inadequate 7.3l Powerstroke was the International Navistar 6.0l turbo diesel.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

Conventional wisdom was that diesel was the only way to deliver significant fuel economy improvements in trucks. However, the growing emergence of direct-injected and turbocharged gasoline engines have made the fuel economy difference between gas and diesel engines much smaller than before. Seredynski said that regardless of fuel, the end goal is the same: maximum power from the minimum amount of fuel. The Ram 1500 Eco Diesel is the current full size pickup mileage champ at 20/28 mpg in EPA testing, but Ford's new 2.7L Eco Boost V-6 gas engine is likely not be far behind. Another enabling technology that has increased economy on both gas and diesel engines are transmissions with much higher gear counts, with six speeds now considered the

For many years, the only way to fuel a car has been through gasoline. Many people believe that it the best form of operation, but recently alternatives to gas have surfaced. Today we opt to purchase hybrid, solar, and electric cars instead of gas fueled. The problem lies in the difference of efficiency of gas fueled cars versus alternative fuel options. Do we need gas fueled cars? Is it worth the extra money for an electric or hybrid car? Do gas fueled cars really affect the environment? Will getting rid of gas fueled cars cause a loss of jobs ? People need to understand that the continuation of gas fueled cars are detrimental to the environment. The replacement of gas fueled vehicles is best for the natural world.

Although some people believe that automobiles have not really changed over time, automobiles have changed an extraordinary amount over the past one hundred years,a plethora of things have changed such as the design of the engine from 1964 to now, the impact of the automobile, and the use of the automobile. There are now over 50 types of engines which include v8s, v6s and 4 cylinders. Over 70 million cars were produced in 2016 alone (worldometers.info). We have reached this milestone by innovating and inventing the technology we use to create these modern automobiles.

Fuel efficiency in automobiles has become a topic of much discussion in recent years in the United States. This is due largely to the environmental devastation that fuel emissions cause, but it is also sparked by the rising fuel costs. Making cars with high fuel efficiency not only saves consumers money, but also will drastically reduce the pollution that is caused by emissions. Today automakers are putting a tremendous amount of effort into making their cars more fuel efficient, both to meet government regulations and to make their car more appealing to the consumer.

These fuel efficiency automobiles would aid the nation to save on the total energy consumed by the citizens and also reduce on the energy expenses thus fostering growth through the transfer of resources to

In the article, “ Why the Gasoline Engine Isn’t Going Away Anytime Soon,” Joseph B. White writes about the reality of the old school, yet productive ways how the internal-combustion engine is going to stay in the competitive market. While at the same time he describes the change for the industry is coming just at a gradual slow pace. For years environmentalists and energy saving specialists could not accomplish what high oil prices did in just a couple years. Changing the game of auto makers focus to make improvements to their engines. The idea of changing from oil to electricity is possible but there is few chances of it succeeding until the future. The author states that cars powerful enough to serve more than one function are the basic need

it? Another factor in the amount of power added by the turbo is the engine’s size. The smaller the

In today’s world there are many different engines that gets assembled in vehicles. The main difference in the engines are if they are gas or if they are diesel. While bearing some minor similarities, the differences between gas and diesel are remarkable.

First, the weight of diesel engines are on average is 1,100 pounds. The engine has to be built stronger, because the compression ratio is a lot higher. As it runs, the pistons compress air to an extreme heat, and as it reaches top dead center, the fuel is injected into the combustion chamber. The fuel being injected directly in the hot air results in a highly destructive explosion that drives the piston down creating power. In addition, it makes the iconic diesel knock sound. Gas engines are built weaker because the compression ratio is lower. If a gas engine had the same compression ratio as a diesel, it would not even start to run because it would blow up at idle. The gasoline engine has spark plugs that ignites the fuel. They don’t need to compress air to an extreme heat like the diesels do. As the pistons travel up, the air-fuel mixture is introduced into the combustion chamber. The air fuel mixture just sits there for a split second, and then the plug sparks and ignites the fuel. This is why the gasoline engines are lighter than diesel.

Abstract – The world can’t be imagined without IC Engines ,as their applications are wider in various fields. And mainly used input for this engines are fossil fuels. But the challenge in this is decreasing rate of resources. The fossil fuels may not be available after some years if they used in the same way .Not only the fossil but also the electric power is the non renewable energy, This paper concentrates to run the engine without fossil fuels or electricity.

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.

These types of engines can be found not only in cars and trucks, but in boats, lawn mowers and generators to name a few.

Unlike petrol engines, diesel engines don’t need ignition system. Due to the inherent property of diesel, combustion will be automatically effective under a certain pressure and temperature combination during the compression phase of Otto cycle. Normally this requires a high compression ratio around 22 : 1 for normally aspirated engines. A strong thus heavy block and head is required to cope with the pressure. Therefore diesel engines are always much heavier than petrol equivalent.
