Fuel economy in automobiles - Wikipedia, the free encyclopedia (2625 words) |
 | Fuel economy is the amount of fuel required to move a vehicle over a given distance. |
| Fuel efficiency can also be hampered by unnecessary friction in the engine where drivers do not take advantage of situations where engine speed could be reduced. |
| As fuel efficiency is related to the complete combustion per fuel molecule in order to get the most energy out of each unit of fuel, the air intake plays a significant role. |
