And what a lot of people do not know, that most big pile drivers are nothing more than a two stroke diesel engine, that does not have a crankshaft... To start, a winch pulls the piston up, then fuel is injected into the cylinder. then the piston is dropped, and compression ignites the fuel which drives the driver down, and the piston up, as once it reaches the top, it drops, onto a fresh charge of fuel, and just keeps going until the fuel is shut off.....

Your trivia lesson for today.....(for those that didn't know it already)
