Combustion engines runs best when they get a fairly narrow range of proportions between air and fuel into the cylinders. If they get more than the needed amount of fuel it's called that they run rich. Means that they'll eject unburnt fuel in the exhaust, clog their spark plugs and basically make a mess of themselves. Engines can run lean too, which means being below the ideal mixture, which isn't really any better.

Is clean air a pure substance or a mixture?
Air is a mixture.
Is air an element mixture or compound?
Air is a mixture, made mostly of the elements nitrogen and oxygen. It also has some other gases, such as argon (element), carbon dioxide (compound), and water (compound).
Which of the following is not a mixture a. pure water b. seawater c. air d. brass?
Answer a. Pure Water is not a mixture - it is a compound. Seawater is a mixture of water and salts, air is a mixture of gases and brass is a mixture (an alloy) of copper and zinc metals.
Why is air a mixture?
because there are many elements and compounds in that make it up, eg, CO2 is a compound, but O2 is an element. This means its a mixture not an element.
What is the fuel mixture 4 hp mercury outboard?
A 4hp Mercury outboard requires a 50:1 fuel to 2 cycle oil mix.
What is it called when there is too much fuel in a fuel and air mixture?
A rich condition.
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
You have black smoke coming from your exhaust?
You are running too rich. the mixture of fuel and air has too much fuel in it,
How do you fix my motorcycle from running rich?
Adjust the fuel/air mixture, ensure you have an unclogged air filter/air cleaner.
What is the ratio of fuel to air in rich mixture?
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.
Why a 110cc pocket rocket spits and sputters?
its possible your air/fuel mixture is too rich
Why push lawnmore smoking?
Too rich of a fuel/air mixture, improper oil/fuel mixture, improper combustion, mechanical malfunction... all possible reasons.
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 the black smoke from the exhaust mean?
It means that the engine is running too "rich"; that is, there is too much fuel in the air/fuel mixture.
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.
