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.

Why is dynamic compression ratio so important to engine durability?
Dynamic compression ratio is important to engine durability by ensuring its compatibility with a specific cam and octane. A higher ratio means the engine derives optimal mechanical energy from an air-fuel mixture.
What is primary air supply?
Primary air supply refers to the initial flow of air introduced into a combustion system, such as a furnace or boiler, to support the combustion of fuel. This air is essential for maintaining the proper fuel-to-air ratio, ensuring efficient and complete combustion. In many systems, primary air is mixed with the fuel before ignition, contributing to the overall combustion process and affecting emissions and energy efficiency. Proper management of primary air supply is crucial for optimal performance and environmental compliance.
What is the fuel-air ratio in a jet engine?
The ratio is about 15:1 fuel to air.
The air fuel ratio of the petrol engine is controlled by?
The air fuel ratio of the petrol engine is controlled by Carburetor
How is fuel air ratio calculated?
The fuel-air ratio (F/A ratio) is calculated by dividing the mass of fuel by the mass of air in a combustion process. It can be expressed as F/A = (mass of fuel) / (mass of air). To determine this ratio, you can use the specific fuel's energy content and the stoichiometric coefficients for the combustion reaction. This ratio is crucial for optimizing combustion efficiency and reducing emissions in engines and burners.
What is a AFR?
Air/Fuel Ratio
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 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
What is mean by air fuel ratio?
the ratio of the amount (mass) of air to fuel. Ideal is 14.7 lbs of air to 1 lb of fuel to completely burn air the fuel. A slightly rich raitio of about 12.5:1 car produce more power at the expense of emissions.
What is air fuel ratio for lpg in furnace?

What is the air fuel ratio in petrol engine?
Ideally it is 14.7 air to 1 fuel in an internal combustion engine.
What ratio of air-fuel is called lean?
A lean air-fuel mixture refers to a ratio in which there is more air than fuel, typically having an air-to-fuel ratio greater than 14.7:1 by weight for gasoline engines. This means that there is less fuel relative to the amount of air, which can lead to more complete combustion and improved fuel efficiency, but may also cause higher combustion temperatures and potential engine knock if excessively lean.
Can air be used as fuel for a car?
Air is used in combination with gasoline at a ratio of 14.7 (air) to 1 (fuel) for an ideal combustion mix.
What does carburetor do?
Mixes fuel and air at the desired ratio for burning.
