Changing the timing events, regarding or advancing changes when the valves open and close. Since only a few degrees is done, the position relative to the piston allows more or less air and fuel in given where the piston is during these events.

Remember, there is a 2:1 ratio on the crank to cam gear. So a few degrees on the cam is a lot on the crank and where the piston is positioned in the cylinder to allow the air and fuel to come in.
