Energysavers.gov,Energy Savers Gov,www.energysavers.gov | USsPost.com:With high energy costs looming on the horizon with the approaching winter, and save money is in everyone’s minds these days. Fortunately, your car and improve fuel economy both economically and environmentally smart. In the winter, one of the easiest ways to reduce gasoline consumption to warm up your engine for a period not exceeding 30 seconds, and Elizabeth said last week. Conservative leadership and buy a car fuel efficiency could be made more impact.
In the 2009 guide fuel economy, which was issued on 15 October, can help you to choose the most fuel efficient car for your needs, new and used alike. Whether you’re in the market for a compact car or small, and provides evidence of the miles per gallon and annual fuel cost per passenger vehicle available this year. And directory on the web, FuelEconomy.gov and his companion mobile site FuelEconomy.gov / m, and a number of special features, in addition to basic statistics.
Let’s talk about the new Department of Energy / Environmental Protection Agency and the economy in fuel consumption, evidence of how drivers can decrease the amount they pay at the pump, I met Dr. David Green, a national expert on the economy in the consumption of fuel in the Department of Energy Oak Ridge National Laboratory.
Shannon: Why should the average person interested in fuel economy guide?
David: I think that the average person should care about fuel economy and directory FuelEconomy.gov for the same reason they care about fuel economy. First of all, fuel economy provides them with money. Car model in the United States, even at three dollars per gallon of gasoline, and will use about $ 2000 of petrol a year. By choosing carefully, when buying new or used car, you can save a significant portion of it. Secondly, for most of us, our cars and trucks are the largest component of the rate of carbon dioxide. The typical car emits about 8 tons of carbon dioxide each year. So there again, we have the means to affect the amount of damage and our vehicle is not on the climate. Finally, there is a problem of our dependence on oil. I do not mean only oil or petroleum imported from some countries. But I mean, our overall strategy of economic and strategic dependence on oil. Our estimates, the economic damage resulting from reliance on oil this year alone, nearly three-quarters of a trillion dollars.
David: So this is not entirely responsible for the economic mess we are experiencing, but it is certainly a contributing factor.
Shannon: How do you calculate the fuel economy?
David: Well, the fuel economy is calculated by the Environmental Protection Agency, and especially by car manufacturers, and the so-called structure dynamometer. So is the device that sits in a laboratory is very large. The car is driven by the board, [with] the front or rear wheels, whichever is [are] the driving wheels, rollers on the drive, and driving over the test session. If you go to FuelEconomy.gov, you can see not only the choices of these test cycles, but you can watch the video of the cars being tested on them. Now, although the cars driven in the laboratory, adjustments are made to take into account such things as aerodynamics and tire rolling resistance, and possibly get a better understanding of worldfuel the real economy. Are tested on two cars – cycle city and highway cycle. In the future, and will be testing vehicles in 5 sessions, which reflect the different conditions, such as cold and weather conditions, reckless driving and the use of air conditioners. Even the Environmental Protection Agency has come up with the new appraisal system based on these courses (5) and we hope to give a more realistic estimation of what is happening people in the real world. Now, after a test session these figures are calculated, they are further adjusted on the basis of the statistical expertise of the real people what’s happening on the road to try and better estimate the average driver is going to get real on the use of such vehicles. There is a downward adjustment that make it before the numbers are placed in gas mileage guide or placed on the Web site FuelEconomy.gov.
Shannon: When I do not expect to start using the new evaluation system?
David: Well, we use the new appraisal system now, but most cars are still tested on two test session.
Shannon: So, the new appraisal system, but still on life-cycle?
David: Right. And manufacturers in the first few years of the transition to 5 tests, a new session.
Shannon: everyone will achieve the same fuel economy and this is written on the label?
David: No. Fuel economy is not in a specific number, such as the weight of a car or a horse. And depends on the fuel economy where you drive, and how you drive. It depends on the temperature when you drive, it depends on whether the trips short or long trips, it depends on the traffic conditions, it depends on many factors. And so, it is a variable. And you have some control over the economy car’sfuel your own, but [there is] also the external conditions such as temperature that can not be controlled. Or lengths of trips you need to be taken. So, you may be able to do something about it by combining trips. But by and large, there are many factors, such as traffic conditions, the economy determinefuel that do not control. And even different people go to get the fuel economy a different experience for the same car.
Shannon: What is a higher vehicle fuel efficiency in common? What makes them so efficient in fuel consumption? [Note: most and least fuel efficient cars are included in the FuelEconomy.gov in 2009, most and least fuel-efficient passenger cars and 2009 and most and least fuel-efficient trucks and vans, and SUVs.]
David: Well, I think, number one is good engineering. And the use of available technologies to increase fuel economy. You will find a large number of hybrid cars, and you will find a disproportionate number of diesel vehicles on the list of fuel economy. But you’ll also find a lot of gasoline-powered vehicles that are simply designed and constructed to achieve the fuel economy high.
Shannon: The diesel vehicles is pretty new, right?
David: Yes. Even in the past two years, diesel vehicles were not able to meet our criteria air pollutant emissions. And only in recent years, manufacturers of diesel technology development necessary to produce these vehicles clean enough to meet the emission standards. Even now that the technology in place, things like special filters that clean the particles from diesel vehicles, NOx catalystics lean or different types of nitrogen oxide control systems, and reduce smog-forming pollutants from diesel vehicles to levels that are as good as vehicles gasoline. So now that those vehicles that may be advanced pollution control technology, manufacturers are beginning to introduce them to the market to see if customers like them.
Shannon: Did they expect to begin to combine some of these techniques together to have a higher fuel efficiency?
David: Well, I do not think we will see very soon, hybrid and diesel fuel, for example. I think we will see many of the hybrid gasoline and we’ll see some more diesel-powered cars. Especially with the diesel cars in the categories of luxury cars and the largest truck classes, where the torque of a diesel engine, which is really good to Qatar, is of particular value. We may see some plug-in hybrid cars that come out in the next few years. This depends on the continued progress the battery. It depends on that, but I think that manufacturers would very much like to introduce these vehicles. I think that first we will see will be a long range electric, but will allow you to plug in the car, and take some energy from the electricity grid, instead of having to buy all your energy in the form of gasoline.
Shannon: What are the unique features FuelEconomy.gov drivers do not offer?
David: The number one feature I think that we offer in your miles per gallon feature, where now about 25,000 motorists across the country have told us the economy whatfuel get with their car. So you can compare the experience of real people with official government classifications. I think that this is very important to the people because they are the basis for comparison. As you can see how many people who have real experience is different, and it will give you a sense of what you may have miles per gallon. There are a number of other features that people find useful. We have a fuel economy advantage, for example, not only can tell you, ‘gets 25 miles per gallon,’ it tells you how much it will cost you to drive this car 25 miles. What is your annual fuel bill is likely to be? Such things. I think we are the only place I know where you can obtain the full assessment on greenhouse gas emissions from cars and light cars and trucks, model year 2009, all the way back to 1985.
Shannon: Now, it is clear that not everyone in the market to buy a new car. What can consumers do to improve the fuel economy of their cars now?
David: Well, first and foremost, as I said, we have the fuel used car valuation: the economy back to 1985, even if you’re in the market to buy new or used car, and the site can help you compare. But there are also a lot of things that people can do in their own leadership to maximize fuel economy. Let me just mention that we have in the Web site of your miles per gallon, these 25,000 people, three-quarters of them beating their estimates of the Environmental Protection Agency. Even if they can do it, you can do it, probably. These are things such as staying within the speed limit. Reduces the speed of your fuel economy. Every five miles per hour you drive over the speed limit will cost you seven or eight percent in fuel economy of your.
Shannon: Yes, this is very important.
David: Also, avoid aggressive driving. Stomping on the gas pedal, and passing of all, the tail so you have to use excessive breaks, and not to anticipate traffic conditions. This kind of things can waste an awful lot of fuel between 5% -30%, depending on how strongly you are driving. That things as well. And then there are the usual things you can do to maintain your car properly maintained, such as ensuring that your tires are inflated properly. Which not only helps the economy in your fuel consumption but it makes your tires last longer and be safer. Scrap of getting a car that you are carrying around in the trunk or in the flat bed of your pickup truck. Such things can also help because every 100 pounds, or what is going to cost you a couple percent in fuel economy. Even if you’ve got in the presence of things that you should be taken out but you’re just carrying it around, you’re wasting fuel. Also, if you have a car top carrier that you do not use, would increase the drag and you can take off and save some fuel as well. Other things you can do and include planning for travel, both to reduce the amount of travel you need to do to make sure that your car fully warmed many as you want at one time rather than many small trips. In fact, it takes a great deal of energy to the engine to warm up for proper temperature.
Shannon: I did not realize how much fuel was used by myself and I read about it recently.
David: So I think if you can plan a little better, then you can certainly provide some fuel. Of course, we have lists for maintenance tips and advice on leadership FuelEconomy.gov.
Shannon: Great. Is there anything you think that people should know about fuel economy or directory FuelEconomy.gov we did not talk about?
David: Well, I think they will find a lot of features in that there is more than we were able to cover. There is everything to information on how to get your tax credit or tax incentives to buy hybrid, a diesel fuel or alternative fuel vehicles to and links to sites that can tell you where you can purchase items E85 to the latest news on the economy in fuel consumption and on and on and day. So I think that people who go there really will find there a wealth of information about this topic.
Shannon: Thank you very much!
David: You’re welcome.
