Depends on the fuel. Type of engine is not important.
For gasoline, a 16:1 ratio would be ideal, for alcohol (Ethanol) 8:1 is considered ideal.
A good estimate for any fuel is to split the difference between Lower Explosive Limit (won't burn; too lean) and Upper Explosive Limit (won't burn, too rich). For example, Propane has a LEL of 24,000 ppm, and HEL of 96,000 ppm, so split the difference and 60,000 ppm should burn pretty well.
60,000 ppm should be about 6% or 17:1.

Kerosine burns the most efficiently at 15:1 ration, however in gas turbines usually operation varies from 45:1 to 130:1 I believe.

What is bleeding of turbine?
Bleed air in gas turbine engines is compressed air taken from within the engine, after the compressor stage(s) and before the fuel is injected in the burner
The main purpose of the turbine in the turbojet engine is to?
The major function of the turbine in the turbojet is that it supplies the power to turn the compressor. An automatic fuel control unit on a turbojet engine is influenced by the burner pressure.
How does a jet engine create thrust?
There are a few different jet engines, but it basically needs bleed air and fuel. Air enters the engine where it is compressed and mixed with fuel. Next, the air/fuel is heated in a combustion chamber, then it is unleashed through the turbine as thrust.
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.
Can a petrol engine run on lean air-fuel ratio such as 30 by 1 while a diesel engine can?
No, the perfect fuel/air ratio is 14.6 to 1. A ratio of 13 to 1 is a safe ratio for most non turbo gas engines. Turbo engines can run a 12 to 1 ratio. Chrysler's lean burn system of the 70's and 80's used a ratio of around 18 to 1 and it was horrible. No gasoline engine can run at 30 to 1.
The air fuel ratio of the petrol engine is controlled by?
The air fuel ratio of the petrol engine is controlled by Carburetor
What is the fuel-air ratio in a jet engine?
The ratio is about 15:1 fuel to air.
What is the air fuel ratio in petrol engine?
Ideally it is 14.7 air to 1 fuel in an internal combustion engine.
What is bleeding of turbine?
Bleed air in gas turbine engines is compressed air taken from within the engine, after the compressor stage(s) and before the fuel is injected in the burner
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.
A smoothly operating engine depends on?
A 14.7 to 1 air/fuel ratio.
The main purpose of the turbine in the turbojet engine is to?
The major function of the turbine in the turbojet is that it supplies the power to turn the compressor. An automatic fuel control unit on a turbojet engine is influenced by the burner pressure.
How does a jet engine create thrust?
There are a few different jet engines, but it basically needs bleed air and fuel. Air enters the engine where it is compressed and mixed with fuel. Next, the air/fuel is heated in a combustion chamber, then it is unleashed through the turbine as thrust.
The turbulence in diesel engine ensures to?
Ensures that all the fuel mixes with the air creating a proper air to fuel ratio to produce combustion.
What is a servo regulator in aircraft?
Regulates the amount of fuel to the engine to maintain the fuel/air ratio at the proper mixture
Why need more air ratio in diesel engine?
make the fuel sufficient burning
What are the functions of the carburetor?
to supply the engine a mix of air and fuel at 14.7 to 1 ratio.
