Is fuel consumed when a car is in gear and going down a hill?
I remember Jeremy Clarkson testing an Audi Diesel from Scotland to London to see how far it would go on a tank of diesel and he made some comment about the car not consuming fuel with your foot off the accelerator?
Answers:
fuel is released when u push the accelerator, most cars have a regulator but some cars such as bmw dont bleed like fords etc so for someone to call u daft is just silly, jeremy clarkson is right, u can ride the clutch an coast without admitting fuel, but u will use more oil and water and damage ur clutch, so coast easy an enjoy the fact ur not often wrong but your right this time xx
If the engine is turned on of course it uses fuel even when standing still.
Any time the engine is rinning, fuel is is being consumed
your car is retarded if your coasting down a hill its like idleing in a parking lot big silly goose but ofcourse it uses more gas climbing the hill its like for a person is it easier to walk up a hill or on level ground
If the engine is running then it is consuming fuel. Plain and simple.
you still consume fuel but not at the rate if you were doing highway speeds
duuuuuh! can you still hear the engine running, well guess what dumb ***, that mean the egines running.. what do you think its running on .. fumes?
IF IT IS RUNNING IT IS BURNING FUEL, JUST LESS WHEN THERE IS LESS LOAD ON THE ENGINE.
Well, of course, while the engine is running, it needs gas to run. What your MPG indicator is saying is that there is no way to compute that ratio, since it needs what the sensors that connect to the accelerator are signaling. No signal means no way to calculate the gas expense, thus it indicates 0 MPG.
My best guess, only!
Well when coasting down a hill of course you are using fuel. But not as much. It also depends if your vehicle is an automatic or manual trans. because an automatic will go to around 1,000 RPM's when you release the throttle.
But a manual trans depending on what gear you are in and how fast you are going is generaly going to stay at the rpm's it was on when you were giving it gas. unless you put it in neutral. but you are still using gas.
If idling your car requires fuel to turn it.
If on 'over-run', ie. it you lift off and the car requires no fuel to continue moving. eg, going down hill in a higher gear than normal, or lifting off the gas when approaching a junction the a modern can will not inject any fuel into the engine as it is not required. This effect can clearly be seen if you have a fuel / trip computer set to display instant consumption. On over-run, it will read as 999mpg instead of a normal amount.
So for the people that say you need fuel to keep an engine turing - how wrong you are.
Yes, because the engine is ticking over.
yes it is
