The engine type with the highest air-fuel ratio is typically the lean burn engine, which operates with a ratio exceeding 18:1, compared to the stoichiometric ratio of approximately 14.7:1 for gasoline engines. Lean burn engines optimize fuel efficiency and reduce emissions by using excess air, but they can face challenges like increased NOx emissions and lower power output. Diesel engines also operate at higher air-fuel ratios, often achieving ratios around 20:1 or higher, contributing to their efficiency and torque characteristics. However, the specific air-fuel ratio can vary based on engine design and operating conditions.

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 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 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
How to adjust air fuel ratio holley 4160?
To adjust the air-fuel ratio on a Holley 4160 carburetor, first, ensure the engine is at operating temperature. Then, use a vacuum gauge or an air-fuel ratio meter to monitor performance. Adjust the idle mixture screws, located on the sides of the carburetor, by turning them clockwise to lean the mixture and counterclockwise to enrich it, aiming for the highest vacuum reading or optimal air-fuel ratio. For more precise tuning, consider adjusting the main jets if needed, but this typically requires removing the carburetor.
What are the functions of the carburetor?
to supply the engine a mix of air and fuel at 14.7 to 1 ratio.
Why need more air ratio in diesel engine?
make the fuel sufficient burning
What is the required Air fuel ratio for a diesel engine?
There is no required a/f ratio on a diesel. It can be as low as 100:1 at no load idle.
What would be the air to fuel ratio of typical petrol engine at cruising speed?
14.7:1
