Rigging a piston engine

The concept of a reciprocating engine, commonly referred to as a piston engine, is in fact quite simple. Petrol gets injected into the cylinder and the piston pushes upwards to compress the petrol (fumes). The spark plug sets of a spark which ignites the fumes and causes it to explode. The force of the explosion sends the piston down through the cylinder. The piston is connected to the crankshaft via a connecting rod, which transforms the up and down movement into a rotation motion which in the end drive the wheels of the car. The piston is connected in pairs so when one piston is pushed down the other is pushed up which compresses the fumes, which is then ignited by the spark plug and so on.
