What is the fuel-air ratio in a jet engine?
The ratio is about 15:1 fuel to air.
What causes power dip when accelerating?
incorrect fuel to air ratio. usually the cars computer or ECU has not adjusted the fuel ammount to compensate for the extra air intake due to acceleration
Do cars need an o2 sensor?
Yes they do. All cars with a computer "80's and newer require an O2 sensor, it gives the computer the amount of air/fuel in the exhaust system so the computer maintains a 14.7.1 fuel ratio .

Where is the air and fuel mixture on VW Polo 2003?
It is controled by the cars ECU (computer) The air fuel ratio on a car cahnges depending on RPM , load on the motor , and air tempature. http://en.wikipedia.org/wiki/Air_fuel_ratio
The air fuel ratio of the petrol engine is controlled by?
The air fuel ratio of the petrol engine is controlled by Carburetor
What are fuel injectors and what do they do?
a fuel injector is an electronically controled fuel releser the fires a small mist of fuel into the air manifold just prior to entering the combustion chamber.. a proper fuel to air ratio is 14 parts air to 1 part fuel and this is monitored by the cars computer from a numerous amount of sensors
What is a AFR?
Air/Fuel Ratio
What is the part of a car engine that begins with CAR?
There is the CARburetor, which mixes the air and gas to the right ratio in some cars. the carburetors have largely been replaced with Electronic Fuel Injection for modern cars.
How do you install air fuel ratio gauge?
Air fuel ratio gauges rely on a sensor that is very much like an O2 sensor used in a car's emmission system. Therefore you would have to have 'bung' drilled and welded into your cars exhaust system to mount the sensor for the air/fuel gauge. After that, run the wiring and mount the gauge like any other aftermarket gauge.
What is stiochiometric air fuel ratio?
It is when the "correct" air to fuel ratio is used to completely burn the fuel in question in an internal combustion engine. If exactly the correct amount of air is used this is called the stoichiometric mix.
What is fuel air ratio?
Air to fuel ratio is the ratio between the weight of air to the weight of fuel, for example: 14.7 pounds of air to 1 pound of fuel would be a air:fuel ratio of 14.7:1 This particular example is called the stoichiometric ratio for gasoline...it's ideal ratio in order to efficiently use all the fuel. This ratio varies for different fuels....for example, ethanol fuels have a stoichiometric air:fuel ratio of 13.85:1. In actuality, a gasoline car gets it's best fuel mileage when the fuel is reduced slightly and produces it's best power when the ratio is a little heavier on the fuel side.
What does a fuel system do?
A FUEL SYSTEM stores, and supplies fuel to the cylinder chamber where it can be mixed with air (air & fuel ratio) to transmit power
