15 to 1 ratio by weight for gas and 7 to 1 for ethynol and methenol. so 1 pound of gasoline needs 15 pounds of air to burn or 197.25 cubic feet of air

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 air fuel ratio in petrol engine?
Ideally it is 14.7 air to 1 fuel in an internal combustion engine.
What would be the air to fuel ratio of typical petrol engine at cruising speed?
14.7:1
What is difference between petrol engine and diesel engine in term of air fuel ratio?
Petrol ideal air/fuel mixture is 14.7 to 1. Diesel, ideal fuel/air mixture is 14.6 to 1. As very few engines run at the ideal mixture they are basically both the same.
What is the fuel-air ratio in a jet engine?
The ratio is about 15:1 fuel to air.
What is the function of the intake system in petrol powered engine?
To supply air to each cylinder on a fuel injected engine and to supply fuel/air on a carbureted engine.
Why diesel engine is more better than petrol engine?
because diesel engine has the maximum efficiency than petrol engine. also diesel engine can handle more load than petrol,as we can see in case in case of heavy vehicles. --- Fuel Savings result because the Air to Fuel ratio is MUCH more "lean" (more air) in a Diesel than in a gasoline/petrol engine. At idle, the optimal mixture for gasoline is 14.7 parts of AIR to one part FUEL. Compare that to a Diesel engine, where the ratio is 50:1, and you'll note a significant savings. --- Other Advantages: Diesel designed his engine to run on virtually any available fuel (e.g.; vegetable oil) for times of short supply of petrol/gasoline. The diesel engine has higher TORQUE, meaning that it can haul larger loads than a gas/petrol engine. There is no Ignition Circuit to fail on a diesel engine. The ignition is achieved by compression and a "glow plug" which remains heated between piston cycles. ---
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 you mix air with petrol in ic engine?
The fuel needs oxygen to burn.
Why is carburetor used in petrol engine but not in diesel engine?
a petrol engine needs to mix its air and fuel before passing it into the combustion chamber before being ignited diesel has its air mixture heated as the piston compresses it in the combustion chamber then the atomized diesel fuel is injected into the hot air and is ignited.
Why is carburetor fitted in a petrol engine?
Used prior to the introduction of fuel injection to mix the fuel & air at the proper mix for an internal combustion engine.
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.
