This video shows what happens inside a four-stroke engine. That's:
1. the intake stroke of the piston, reducing pressure in the cylinder and forcing gas and air inside
2. intake and exhaust valves close and the piston compresses the fuel-air mix
3. the compression and a spark result in combustion, and therefore a power stroke
4. the piston compresses, pushing out the expended fuel-air mix

Clever photography, but the flame path on that engine is screwed. Needs some work.

Exactly, the video skips one step. Something is wrong.

Why doesn't it doesn't show the exhaust stroke?
