...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 bare minimum, just as eight-speeds and higher are starting to become the norm. Refinement: Gas, But Barely Diesel engines have evolved tremendously over the last 20 years in almost every area, but perhaps the most impressive strides have been made in the area of noise, vibration and harshness. In the '80s and '90s, it was not uncommon to have to turn your engine off in the drive-through so the cashier could hear your order. On some of today's trucks, the engine type is almost unnoticeable from the driver seat. The biggest enabler of this is vastly more refined injection technology, which has made diesels nearly the peer of their gasoline counterparts. In the case of direct fuel injection, the technology has had a different effect on gasoline and diesel engines...

...Diesel Vehicles By: Brandi Roeder Environmental Science Rick Henry There are many different types of fuel used to power a vehicle, some of which include solar, electrical and diesel. Out of these fuel types I would choose diesel as the best. There are advantages and disadvantages in all types of fuel sources. Solar and electrical are good environmentally but the diesel overpowers in all categories. Diesels are the better choice of all the fuels in my opinion. I would choose a diesel fuel because according to Consumer Reports they have a 30% better fuel economy than a gasoline vehicle. Also they are more affordable than a hybrid vehicle. According to The Diesel Page, diesel engines get better mileage than gasoline engines. Diesel engines also do not have spark plugs or distributors so you do not need to worry about the usual maintenance of these two things. Diesel engines are built to be used for hauling and they usually also last longer than gasoline engines (Health Research Funding). While speaking of hybrid vehicles, let’s backtrack to the solar and electrical vehicles. According to How Stuff Works solar powered cars have many practical problems with them. Solar powered cars do not gather enough energy to move the car very quickly, there cannot be too much weight in the car otherwise it will slow it down and use more energy. Solar cars also do not have a very good way to store energy. The layout for solar power is good for buildings, but it is much too heavy to...

...Introduction The Lotus Rental Car’s Chief Financial Officer is making an assessment on the feasibility of adding alternative fuel vehicles to the fleet. This analysis will cover the Energy Act of 1992 concerning the alternative fuel sources, explain the pros and cons of using alternative fuel technology such as Hybrids, Battery power, Diesel, Biodiesel, and Natural Gas, and also the factors that will impact the American people having to find resources easily, which can be difficult. Energy Act of 2005 As early as 2005 the United States knew that we could not rely on fossil fuels indefinitely and did not want to rely on foreign oil. The Energy Act of 2005 sec 301 defined what the Alternative Fuels are: Ethanol, Biodiesel, Propane, Natural Gas, Hydrogen, and Electricity are all naturally produced domestically in the US. Currently the US has learned that burning gasoline is bad for the environment, and when you burn gas you create bi products such as Carbon Dioxide, Nitrous Oxide. According to an EPA study the Green House gasses that affect out atmosphere are made up of 82% Carbon Dioxide, 3% Fluorinated Gas, 6% Nitrous Oxide, and 9% Methane.(Refer to graph 1). Overview of Green House Gases EPA.gov As you can see the bulk of the emissions are carbon monoxide and carbon dioxide. The global goal is to reduce the amount of carbon emissions in the world, not just in the US. The goal is to create a smaller carbon footprint...

... There has been a recent shift in the consumer’s mind set as far as environmental consciousness, as well as the consumer’s overwhelming vocal concerns over emissions destroying the ozone. Even though electric cars do not put out the high emissions, the batteries these cars must use are worse for the environment because the chemical makeup is harsher for the eco system, and tests have shown a regular battery does less damage to the environment (Cherry,2010). The workings of a gas/diesel engine are very different from that of an electric car engine. Where the gas/diesel engines use fuel and combustion, the electric car runs solely on a battery. There are hybrids that use both a fuel engine and alternately run off of a battery, but they are in another category. A fuel engine uses the spark from a spark plug to ignite the gasoline fumes inside the carburetor which starts the engine, whereas a diesel engine uses hot air to ignite the diesel fuel fumes. Gasoline engines run hot externally while a diesel engine runs hot internally. After both of these engines are started and running, they emit what is called emissions from the exhaust. The emissions from these types of vehicles are what, according to the Green movement and some scientists, is to blame, in part, for the hole in the ozone (Britanica, 2012)....

Of these, diesel comprises 70% of that growth (figure 1). This shift away from gasoline to diesel is driven by better light vehicle fuel economy and the growth in commercial transportation that comes from developing nations (Exxonmobil 2013). Although diesel is becoming the more prominent...

...Compressed Natural Gas more commonly known as CNG is as form of Natural Gas which is used in the transport sector. Natural gas is a mixture of hydrocarbons mainly methane (CH4) and is produced either from gas wells or in conjunction with crude oil production. Due to its low energy density for use as a vehicular fuel, it is compressed to a pressure of 200 - 250 bars to facilitate storage in cylinders mounted in vehicle and so it is called compressed natural gas (CNG). There are abundant supplies of natural gas in the world and most of these supplies can be developed and produced at a low cost as compared to other natural resources. Natural gas is one of the most cost effective means by which we can maintain the energy supplies but also reduce CO2 emissions. Natural gas is important in many sectors of the economy. It can be used for varied purposes such as electricity generation, an industrial heat source and can also we used for water and space heating in residential or commercial buildings. It can use to substitute petrol or diesel in the transportation sector. Among the fossil fuels natural gas has the lowest carbon intensity, hence emitting the least amount of co2 per unit of energy generated compared to other fossil fuels. It burns cleanly and efficiently with very few non carbon emissions. It requires limiting processing unlike oil. CNG is a clean burning fuel. Since it is mainly composed of methane, when burnt is produces carbon dioxide and water vapor which are the...

...culture has changed and changed again in response to new additions which have woven their way into our lives. But, none has affected our society as deeply as the automobile. From the way we work and play to how we design the buildings we call home, the automobile has created in many ways a car culture with its own status symbols. However, while the automobile has changed the lives of us all in a positive light; this does comes with a price, and the price is our environment. Currently “cars and other highway vehicles continue to emit some 60 million tons of carbon monoxide per year. Motor vehicles also emit as much as 50 percent of our carcinogenic and toxic air pollutants, such as benzene and formaldehyde. And heavy vehicles, particularly diesel-powered buses and freight trucks, constitute a significant source of soot and other unhealthy fine particles that, when inhaled, lodge in and damage human tissue.” (Turk, J & Bensel, T 4.3) In this paper, I am going to debate why cars should be made more efficient for the sake of saving the environment in which we live in. I will then give the different options as to how cars can be built to be more efficient; and then, debate as to why these options would not be a wise decision for some. Even with all the different makes and models of cars being sold today; it is still difficult to find one that best fits you, you’re wallet, and the environment all together. With that being said; let’s look at the hybrid. There are a lot of pros...

...Efficiency of Hybrid cars Have you been to the gas station lately? Have you been shocked with the high fuel prices? When the price went beyond $40 or higher you must have thought for a second to trade in your SUV for a car with a better gas mileage, or you even might have thought about global warming. The car industry has found a technology that has an answer for these questions. The answer is the hybrid car. Most of the big car manufacturers have a hybrid model on the market. You might have heard about some or even seen some driving down the street already. Hybrid cars work differently than other cars, they are made differently than other cars, they perform differently than other cars and they are more efficient than other cars. How does a hybrid car work? What is it that a hybrid car is so much more efficient than a normal car, and is it really better for the environment because the gas mileage is so much better? In this essay I want to explain how this amazing technology called hybrid car works. What makes a car a hybrid car? Every vehicle is a hybrid when it uses two or more energy sources. In fact, a lot of people have owned or still own a hybrid. For example, an electronic bike is a hybrid because it combines the power of an engine with the force that comes from people using the pedals. Hybrid vehicles are everywhere around us. A lot of diesel locomotives pulling trains are diesel-electric hybrids. In cities like Seattle, they use diesel-electric busses. These busses use power...

Rudolf Diesel and his invention diesel engine is the object of the paper. The goal of the paper is to analize this invention, talk about Rudolf Diesel and his theory of diesel engine, its advantages and disadvantages, types and working principles. The diesel engines of today are refined and improved versions of Rudolf Diesel's original concept. They are often used in submarines, ships, locomotives, and large trucks and in electric generating plants. Technology has affected society and its surroundings in a number of ways. In many societies, technology has helped develop more advancedeconomies (including today's global economy) and has allowed the rise of a leisure class.

...Alternative fuel Opportunities "Most of the observed increase in globally averaged temperatures since the mid-20th century is due to the observed increase in anthropogenic greenhouse gas concentrations"(E.E.R.E.) If there isn’t some form of a major change in the way we use, renew, and obtain energy our world will be severely effected. By 2100 if we continue at the rate we are going with fossil fuel abuse there will be an average increase of forty-eight-degrees Fahrenheit to the global temperature (E.E.R.E.). Many people believe that the effects of global warming are not going to occur until centuries from now, but reality is that there are changes already happening. Sea levels are currently rising due to glacial retreat and arctic shrinking (E.E.R.E.). There are also severe long term effects. Some major events would be severe weather events such as an increase in the more violent hurricanes and tornadoes, reversal of seasons, and even sever economic depression due to a decrease in crop production. There are many different solutions or alternatives to our current declining global situation. Cars can be powered by bio diesel, ethanol, electricity, fuel cell, hydrogen and a combination hybrid (Alternative Energy). The possibilities are endless for future possibilities to fuel our power hungry world. All it would take for our ecosystem to be saved is a little time and a slight bit more money, if nothing is done future generation will perish. A large portion of our global warming...
