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 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.
Even though the updated engine configuration uses richer air - fuel mixtures and more spark advance, Volvo says the C70's fuel economy ratings of 19/28 mpg (city / highway) are unchanged.
As the upstroke happens the pressure in the cylinder is now low because the escaping exhaust gases cause a small pressure wave of escaping gas that now opens the reed value and draws in new fuel / air mixture.
The damage is often the result of an incorrect air / fuel mixture, incorrect timing, or misfiring spark plugs.
This depends on air velocity and temperature of your air / fuel mixture.
A misfire occurs when a cylinder fails to ignite the air / fuel mixture at the right time and could happen due to a wide range of reasons, including lack of spark (a bad coil), lack of fuel delivery (clogged fuel injectors) and improper ignition timing (out - of - spec cam timing).
Due to the behavior of the working fluid (air and fuel mixture) before and after combustion, which have physical limitations on their flow, as well as their interaction with the ignition spark, the optimal valve timing, lift and duration settings under low RPM engine operations are very different from those under high RPM.
A higher percentage of fuel to air is described as a rich mixture, while a lower percentage of fuel to air is termed a lean mixture
The spray and cone angles have been optimised for torque, power output, fuel consumption and emissions by enabling a homogeneous distribution of the air / fuel mixture and, therefore, effective combustion.

Portion of the engine where the air / fuel mixture is ignited and converted to mechanical energy; includes all the space above the piston at top - dead - center (TDC), including the cylinder head, which forms the top of the combustion chamber.
This induces swirl of the intake charge which improves air / fuel atomization in the cylinder and allows for a leaner fuel mixture to be used.
