关于能源效率的事实

能效是核心价值。它也是美国石油和天然气工业的日常实践。能源效率有助于公司管理成本,加强竞争力,并为消费者带来更实惠的能源产品。今天,美国比发代前更节能。美国石油和天然气产业正在努力实现这一部门的建立。

关于燃油效率的常见问题

You can use energy more wisely if you remember CAMS – Combine trips, Accelerate smoothly, Maintain your vehicle, and Slow down.

我能做的最好的事情是为了节省汽油?

结合旅行。计划康复,对你开车有多敏感。通过避免不必要的旅行,结合差事和拼车来保护。

When I am behind the wheel, how can I get more miles per gallon?

加速顺利。Jackrabbit开始消耗两次燃料作为逐步开始。另外,你的驾驶。保持恒定速度优于连续加速和放慢速度。慢下来。你开车的速度越快,汽车用途越汽油。每小时65英里的驾驶而不是每小时55英里,每加仑大约两英里减少燃油经济性。

Besides changing driving habits, what can I do to improve vehicle fuel efficiency?

Maintain your vehicle. Have your car tuned regularly and keep tires properly inflated. An engine tune-up can improve car fuel economy by an average of one mile per gallon; under-inflated tires can reduce it by that amount. Also, less use of your air conditioner can improve fuel economy by as much as two miles per gallon.

我开车的车有所作为吗?

More fuel-efficient vehicles can save gasoline. A highly fuel-efficient vehicle could potentially cut gasoline use in half or more. How much depends on the vehicle and driving habits and needs. If a less fuel-efficient car requires 20 gallons of gasoline a week compared with 10 gallons for a highly fuel-efficient vehicle, more than 500 gallons of gasoline could be saved annually.

What about ethanol?

Ethanol, which is often blended in gasoline, contains less energy per gallon than gasoline. However, a 10-percent or less ethanol blend would have only a slight impact on fuel efficiency. According to U.S. Department of Energy and U.S. Environmental Protection Agency fuel economy guidelines, E-85 (85 percent ethanol/15 percent gasoline blend) may reduce fuel efficiency by 26 percent.

Can I avoid fuel evaporation and loss by keeping my tank almost full?

它不应该是一个问题。车辆燃料系统的技术变更几乎消除了燃料蒸发损失。

Does it help to fill up in the morning when fuel is cool?

Very little. While it’s true that gasoline expands as it gets hotter (reducing the energy content in a given volume), the expansion is only about one percent for every 15 degrees F. Moreover, storage tanks at gasoline stations are buried several feet underground, helping to insulate fuel and keep temperature relatively constant. The benefits, if any, of filling up in the morning versus the evening would be hard to notice.
