The air-fuel ratio (AFR) significantly affects engine performance by influencing combustion efficiency, power output, and emissions. A stoichiometric ratio (around 14.7:1 for gasoline) ensures optimal combustion, maximizing power and minimizing unburned fuel. Deviations from this ratio can lead to incomplete combustion, resulting in lower power, increased emissions, and potential engine damage. In contrast, a richer mixture (more fuel) can enhance power but may increase emissions, while a leaner mixture (more air) can improve fuel economy but risk engine knock or overheating.

What is injection ratio?
Injection ratio refers to the proportion of fuel injected into an engine's combustion chamber compared to the air or total mixture during the combustion process. It is a critical parameter in determining engine efficiency, performance, and emissions. A well-optimized injection ratio ensures complete combustion, enhancing power output while minimizing pollutants. Adjustments to this ratio can significantly impact engine operation, fuel economy, and overall performance.
Why does fuel ratio vary?
Fuel ratios vary due to differences in fuel types, combustion conditions, and engine design. Each fuel has a specific energy content and combustion characteristics, requiring adjustments in the fuel-to-air mix for optimal performance. Additionally, factors like altitude, temperature, and load conditions can influence the ideal fuel ratio to ensure efficient combustion and reduce emissions. Engine tuning and performance goals also play a crucial role in determining the appropriate fuel ratio.
The air fuel ratio of the petrol engine is controlled by?
The air fuel ratio of the petrol engine is controlled by Carburetor
How do you set air flow on a fuel injected engine?
The engine control computer keep the fuel ratio at 17 to 1. This has been found to give the best performance and fuel mileage. There is not any manual adjustments to be made.
What is the fuel-air ratio in a jet engine?
The ratio is about 15:1 fuel to air.
What is mixture ratio of Rocket Propellants?
The mixture ratio of rocket propellants refers to the ratio of oxidizer to fuel in a rocket engine. It is an important parameter that determines the performance and efficiency of the engine. The specific mixture ratio can vary depending on the type of propellants used and the design requirements of the rocket.
Correct air and fuel ratio on idling?
The correct air-fuel ratio for a gasoline engine at idle is typically around 14.7:1, which is the stoichiometric ratio for complete combustion. However, this ratio can vary depending on the specific engine design and operating conditions. For optimal idling performance, some engines may operate with a slightly richer mixture, such as 12:1 to 14:1, to ensure smooth operation and reduce the risk of stalling. Adjusting this ratio is crucial for engine efficiency, emissions control, and overall performance.
How can I optimize my car's performance with a tuning service?
You can optimize your car's performance with a tuning service by adjusting the engine's settings to improve power, fuel efficiency, and overall driving experience. Tuning can involve modifying the engine's computer system, adjusting the air-fuel ratio, and enhancing other components to maximize performance.
What is cut off ratio?
a percentage or amount of something AE: the fuel. there is a cut off ration on your fuel system so that your engine does not flood out and stop running.. or burn up.. its main purpose is to improve gas mileage and air fuel ratio. increasing performance
Does it affect the car if you put either unleaded or leaded petrol in a car?
It can effect engine performance and fuel burning efficiency.
