This is in part due to the compression ratio of the cylinder, how much the piston squeezes the air - fuel mixture in the engine.

The traditional cylinder - piston design used in engines means that only the piston head itself produces motive force, as it is pushed up and down by the expansion of the burning fuel - and - air mixture.

It will focus on catalyst development for four applications: proton exchange membrane fuel cells to convert stored energy in non-fossil fuels into electricity; electrolysers for splitting water into oxygen and hydrogen — a potential clean fuel cell source; syngas, a mixture of CO and H2, which is generated from coal, gas and biomass, and widely used as a key intermediate in the chemical industry; and lithium - air batteries.

In direct Injection, the injector sprays the air fuel mixture directly into the cylinder thus you have optimum computer controlled combustion.

Also these engines are basically just normal gasoline engine that accommodate ethanol with proper air / fuel mixture.

Jim theorizes that low coolant caused portions of the engine to get too hot, so the temperature sensing computer thought it was very cold outside, and made the fuel - air mixture too rich (less air).

On the other hand, a spark plug which is too cold, will tend to not burn all of the air fuel mixture within the cylinder, which also means worse gas mileage and sub-par performance as well.

If they do it is usually at the fuel pump and would not impact your air / fuel mixture in any way.

Typically bad emissions are due to an incorrect mixture of air and fuel.

As @Fred Wilson mentioned in his comment, if the MAF sensor that you replaced isn't the one made specifically for your car, then it won't be able to correctly control the air fuel mixture.

There are basically 3 things you need to consider for timing - engine RPM, air / fuel ratio, and volume of air fuel mixture in the cylinder.

What the ECU does is create a very specific mixture of this fuel, vapor, and air that is needed to create the high energy burn that makes the engine turn.

@MeltingDog, if by flooding you mean that the air - fuel mixture is too rich for ignition to take place then yes, that is the hypothesis.

The fuel / air mixture gets sucked through the engine like normal but fails to combust due to being too thin.

This tells me that the cold - start enrichment, where the air - fuel mixture entering the cylinders is slightly rich, isn't taking place.

It turned out to be the air fuel mixture, fiddling with the little adjustment screw on the carburettor sorted out the problems.

A couple that come to mind are the volume or air / fuel mixture (Why timing is advanced when under less load / higher vacuum) and air / fuel ratio (why timing is pulled when the engine is cold).

The air fuel mixture is compressed by the rising piston.

Using a lower octane fuel than recommended can result in the fuel / air mixture self - igniting (commonly called «knocking»).

On my car, I know that below a certain amount of manifold pressure (30kpa on my car, 100kpa being atmospheric pressure) the fuel / air mixture can't reliably combust.

The result is an incorrect air - fuel mixture than can create a number of problems, such as hard starting, a rough idle, hesitation, misfiring or a drop in fuel economy — issues that could, without proper diagnosis, seem to have other causes, such as incorrect ignition timing or fouled spark plugs.

The stalling symptom is an indication that the air - fuel mixture is not being metered correctly.

Once this mixture of fuel droplets, and air is inside the cylinder, and a spark occurs do the air molecules gain kinetic energy, then collide into the atomised fuel, and the individual fuel molecules break apart thus turning fuel from a liquid to a gas (vaporisation), then those fuel molecules combines with the air molecule, then combustion occurs?

This flame ball sends a shockwave down towards the upcoming piston, producing an effective secondary piston, squeezing the air / fuel mixture.

High (CO) is the result of one problem, a rich air / fuel mixture but may have several causes.

When this happens, the air / fuel mixture becomes outside of what is ideal, and perhaps outside of what is even stoichiometric.

Based on what's been described, I'd say it's probably because the air - fuel mixture isn't right.

Their primary role is to provide feedback to the fuel management to determine if the air - fuel mixture being fed into the engine is being mixed in the right ratio.

This is because it will have a race camshaft which opens the inlet valves very early, it may hold the inlet and exhuast valves open at the same time to improve chamber filling using the negative pressure in the exhaust (i.e. scavange it's inlet plenum) and it will keep the valves open for as long as possible to let the maximum about of air / fuel mixture into the cylinders.

If the air filter is clogged enough, the resultant air - fuel mixture could be too rich for fuel management to rectify, resulting in sputtering / stalling.
