Yes, it just depends on how much vapor and for how long. If there is a lot of vapor, then combustion can occur, all you need is enough oxygen to react with it (which is not more than the amount required with liquid fuel). The liquid fuel in your engine is converted into a gas anyway (when it enters the cylinder)

The stoichiometric ratio of air to fuel is 14.7:1. That is the ratio that would, given a perfect combustion environment, yield a perfect "burn" of the air and gas, where there would be the greatest amount of energy created, and the least by-products ("pollution").

But, of course, little in this world is perfect, so engines have to run a little richer than that to prevent pre-detonation, and to prevent damaging temperatures in the combustion chamber.

Air is required; it requires about 17 times as much air (by weight) as fuel. The typical chemistry: C7H16 [m.w. 100] + 11 O2 [total m.w. 352] -> 7 CO2 + 8 H2O. Since air is only 21% oxygen, you have to multply by five. That's why you have an air intake, air cleaner, etc.

It is actually a much larger air percentage then fuel. Atomized gas mixes with oxygen making it more volatile. The old saying is something like "one sip of gas to three gulps of air"

Liquid gasoline is taken to the level of a fine mist and then it must be combined with a large amount of air (oxygen) and then a spark combusts it. this is an explosion and it makes the piston in an engine go downward.

It needs gasoline and oxygen that is in the air to make a explosion that forces the pistion down to turn the driveshaft and wheels. As it goes back up it pushes out the smoke out and goes around again for another explosion. Does that over and over very fast.

Both. Before it gets injected into the engine, the fuel is mixed with air. Otherwise, it won't burn.

I'm not sure exactly how much air an engine uses, though.

air (oxygen) is used more than gas in engines. because a molecule of gas has around 6 carbon atoms. for burning a molecule of gas we need 6 molecules of O2 to produce CO2

sounds like you have huffed on large quantities of gas vapors

It requires both air and fuel mix to cause combustion.
