Decreased performance and fuel mileage.
The engine control computer keep the fuel ratio at 17 to 1. This has been found to give the best performance and fuel mileage. There is not any manual adjustments to be made.
The air fuel ratio of the petrol engine is controlled by Carburetor
The ratio is about 15:1 fuel to air.
It can effect engine performance and fuel burning efficiency.
a percentage or amount of something AE: the fuel. there is a cut off ration on your fuel system so that your engine does not flood out and stop running.. or burn up.. its main purpose is to improve gas mileage and air fuel ratio. increasing performance
A fuel level sensor will not affect performance. Fuel level can due to weight of fuel and accumulated heat in the returned fuel from the engine.
In diesel engine fuel to power ratio is 1:50
Fuel injection gives the best air to fuel ratio for best performance and efficiency.
It depends on the engine.
Gear ratios will let the engine run at the speed and load at which it is most efficient, which is good for low fuel consumption and an exhaust that is as clean as possible.
Yes, the higher the compression ratio, the more octane the fuel has to be. Anything over 10.0:1 has to be 91 or higher. However, if performance is not an issue, than you can use any type of fuel you want, but car will not accelerate fast and its torque curve will be very bad. Using low octane fuel in a high compression engine will also cause knocking (pinging, pinking). This will cause damage if continued.
