What is the meaning of air-fuel?
Definition of air gas 1 : a combustible gas made by charging air with the vapor of some volatile hydrocarbon mixture (as gasoline) and used for lighting and heating. 2 : a producer gas consisting chiefly of carbon monoxide and nitrogen and made by blowing air into a producer.

What is air-fuel ratio and why is it important?
The air–fuel ratio is a significant indicator and very important measure for gasoline engine performance controlling and tuning, and anti vehicles exhaust emissions pollution reasons. The AFR called or known as stoichiometric mixture when the provided air is exactly enough to completely burn all of the gasoline fuel.
What are the 3 types of air-fuel mixture?
There are three types of Air-Fuel Mixture, they are as follow:
- Stoichiometric Mixtures.
- Rich Mixtures.
- Lean Mixtures.
How is fuel and air mixed?
The stoichiometric mixture for a gasoline engine is the ideal ratio of air to fuel that burns all fuel with no excess air. For gasoline fuel, the stoichiometric air–fuel mixture is about 14.7:1 i.e. for every one gram of fuel, 14.7 grams of air are required.
What is meant by air-fuel ratio?
Definition of ‘air-fuel ratio’ The engine allows for a particularly low air-fuel ratio during warm-up to reduce emissions of unburned fuel. The electronic control unit recalculates the air-fuel ratio for the most efficient operation.
What is rich air/fuel mixture?
Rich fuel mixture is a type of air-fuel mixture that has less air than the required quantity of air for the complete combustion of the fuel. These air-fuel mixtures are less efficient. It is because these mixtures lack the air required for the complete combustion of the fuel.
What is air-fuel ratio for combustion and what is a rich mixture?
When the air fuel ratio is lower than the stoichiometric ratio, the air fuel mixture is called rich. For example, for a gasoline engine, an AFR of 16.5:1 is lean and 13.7:1 is rich.
What is good air/fuel ratio?
The ideal air-fuel ratio that burns all fuel without excess air is 14.7:1. This is referred to as the “stoichiometric” mixture. In this case you have 14.7 parts of air for every 1 part of fuel.
What is the air fuel mixture unit?
Air fuel ratio definition Air fuel ratio is defined as the ratio of air and fuel of a mixture prepared for combustion. For example, if we have a mixture of methane and air which has the air fuel ratio of 17.5, it means that in the mixture we have 17.5 kg of air and 1 kg of methane.
What’s the difference between lean and rich?
Lean means your vehicle is fuel-starved. If you have too much gasoline in the air/fuel mixture, this is what is called a “rich” air/fuel mixture.
What is air-fuel ratio and carburetor?
What is Air-Fuel Ratio in a Carburettor? The carburetor’s main function is to mix the fuel with air in a perfect ratio. It does so according to the engine’s speed and load conditions. Theoretically, the ideal mixture contains 15 parts of air and 1 part of gasoline fuel. Thus, it provides the air-fuel ratio of 15:1.
What are the types of air fuel mixtures?
– Chemically correct mixture or Stoichiometric mixture – Rich mixture – Lean mixture
What is the best air fuel ratio?
68chevelle_ss. I have a digital wide band air/fuel ratio meter and am looking to find the proper air/fuel ratio.
Why is air fuel mixture enter in cylinder of engine?
This mixture is caused to undergo combustion at the proper time by a spark, generated by the spark plugs. The properly timed explosion of the fuel air mixture in the cylinder drives a piston, which is in turn connected to a crankshaft, which spins the propeller.
