Opposed Cylinder engines

[sprintcyclist]

It is a weird engine isn't it ?

2 pistons in the same cylinder.
Moving toward and then away from each other.
When they nearly hit in the middle of the cylinder, fuel is injected, ignition occurs.
On the power stroke both cylinders move away from each other.

Yeah I found it hard to see how the exhaust was forced out one end and the fuel in from either end after a firing. I sort of thought the firing would cause outward pressure both ends.
