Air–fuel ratio (AFR) is the mass ratio of air to a solid, liquid, or gaseous fuel present in a combustion process. The combustion may take place in a controlled manner such as in an internal combustion engine or industrial furnace, or may …

The AFR defines the ratio of the amount of air consumed by the engine compared to the amount of fuel. A 'Stoichiometric' AFR has the correct amount of air and fuel to produce a chemically complete combustion event .

To optimize your engine’s performance, you need the right mixture of air and fuel. AFR stands for air to fuel ratio. Fuel doesn't burn on its own. It has to be mixed with air. AFR tells you how many parts of air are mixed with each part of fuel. For example, a 14.7:1 AFR (or just 14.7) means the mixture is 14.7 parts air to one part fuel.

The safest air/fuel ratios are continuously being debated, but it is widely accepted that 13:1 is a good ratio for normally aspirated engines and 12:1 is good for forced induction engines. Many choose to go even richer, even 11.5:1.

2017年5月26日 · This is also known as the air/fuel ratio, or AFR for short. By ‘a bit rich’ we mean there is too much fuel being fed into the engine, and by ‘a bit lean’ we mean there is not enough fuel, therefore the air/fuel ratio is incorrect and needs adjusting to get the balance right again.

The air-fuel ratio (AFR) is a critical parameter in combustion processes, representing the ratio of the mass or volume of air to the mass or volume of fuel in a combustion mixture. It is a fundamental concept in internal combustion engines, industrial burners, and …

The AFR for maximum power is usually between 12-13:1, depending on how well mixed the vapour was beforehand. The extra fuel increases the likelihood of the free oxygen being closer to a fuel molecule for the reaction.

Air fuel ratio or AFR refers to the mass ratio of air to fuel involved in a combustion cycle. The AFR is important as the amount of fuel injected into the engine is one of the most significant combustion parameters that the ECU can control. The ECU takes the target AFR and determines the correct mass of fuel to inject based on the mass of air ...

Troubleshoot vehicle tuning in minutes with the SAFR (Standalone Air Fuel Ratio) diagnostic tool. Boasting the ability to measure the full scale of AFR values, the SAFR supplies motorsport enthusiasts the information necessary to accurately understand their vehicle's operation.

The air-fuel ratio (AFR) represents the mass of air needed for complete combustion of a given mass of fuel. A higher AFR means more air is required per unit of fuel for complete combustion.
