FAQ:
Q: What is the best air fuel ratio?
A: The ideal (theoretical) air-fuel ratio, for a complete combustion, is called stoichiometric air-fuel ratio. For a gasoline ( petrol ) engine, the stoichiometric air-fuel ratio is around 14.7:1. This means that, in order to burn completely 1 kg of fuel, we need 14.7 kg of air.
Q: What should my air fuel ratio (AFR) be?
A: The for normal cruising, the ideal A/F ratio is 14.7:1 and that will result in the most efficient burning. For running boost, though you’ll be getting knock real fast. For a conservative level, between 12:1 and 13:1 would be fine.
Q: What is a wideband oxygen sensor?
A: A wideband oxygen sensor (commonly referred to as a wideband O2 sensor) is a sensor that measures the ratio of oxygen to fuel vapor in the exhaust exiting an engine. The measured ratio is expressed as parts of oxygen to fuel. If there is 15 parts of oxygen to every one part of fuel, this would be expressed as an air/fuel ratio of 15 to 1, or 15.0:1.
Q: What is the air to fuel ratio?
A: For a gasoline engine, the perfect air to fuel ratio is 15:1 (15 parts air to 1 part fuel by weight). Under constant engine conditions, this ratio can help assure that all fuel is burned during combustion.
