Gas doesn’t explode. It burns just like diesel does but at a different rate. If it exploded it would blow the head right off the engine. It is a controlled burn.
The energy is not all over in one shot. There is pressure derived all the way through the power stroke otherwise there wouldn’t be any point in having much of any stroke in an engine.

If the piston was pulling vacuum as it neared the bottom of the stroke then there wouldn’t be any need for the exhaust stroke. No fire would ever come out the exhaust.

Both diesel and gas engines operate in a similar manor but differ in the way ignition is performed. The diesel relies on high compression to produce enough heat to self ignite the fuel but once ignited the rest happens almost the same.
