Well the preferred ratio is 14.7:1 (14.7(air):1(fuel)) so anything below this is rich.... 14.6:1 for e.g

What does mean lean mixture or rich mixture?
The ideal fuel/air mixture or ratio for most internal combustion gasoline engines is 14.7 to 1. Meaning 14.7 parts air to one part gasoline. Any ratio below this is considered a rich mixture or too much fuel. Any ratio above this is considered a lean mixture or too much air.
What is the effect of air fuel ratio on detonation in internal combustion engine?
A leaner fuel mixture burns hotter than a rich mixture. so a leaner mixture will be more prone to detonation than a richer mixture.
Could a closed or open thermostat cause a computer controlled fuel system to run rich?
No. The stochiometric ratio is a matter of fuel/air mixture... coolant has nothing to do with it. If you're running rich, you don't have enough air going into that mixture. Perhaps your air filter is past due for a change.
What is it called when there is too much fuel in a fuel and air mixture?
A rich condition.
What is the air to fuel mixture ratio?
14.7 to 1 is the sweet spot.
Can someone tell me why my 65 mustang's exhaust smells like gas and is abundant?
the air to fuel ratio mixture needs to be adjusted its running too rich.
Can a rich air fuel mixture cause engine blow by?
Yes
How do you fix rich air fuel mixture?
install a cold air intake. more air with same amount of fuel being injected will lean out the fuel/air mixture. plus you'll get more power
What does stokiometric mean?
Stoichiometric refers to the precise proportions in which substances react or combine in a chemical reaction to form products. It is based on the ideal ratio of reactants to produce the maximum amount of products without any excess or unreacted reactants.
What is the effect of air fuel ratio on BHP and SFC?
Too rich or too lean of a mixture, and both will be affected negatively. Unleaded gasoline/petrol is especially specific with the stochiometric ratio it requires for ideal combustion.
What would happen if we change the Ratio of Fuel and Air Mixture in an any Engine?
Increasing the ratio of air to fuel (known as a 'lean' mixture) will result in hotter combustion gases and less power. However the exhaust will contain less Carbon Monoxide. Increasing the amount of fuel (a 'rich' mixture') will result in cooler cobustion gases, more power, but overall it is less-fuel efficient. It also produces many more gases such as Carbon Monoxide, due to incomplete combustion of the fuel.
What is A good fuel-air mixture for an automobile?
stoichometric ratio is considered 14.7:1 air:fuel by mass any thing below 14.7 is rich, anything above is lean.
