The aft end of the crankshaft connects to the propeller shaft through the thrust bearing.
The connecting rod connects the piston to the crankshaft .
The resulting explosions of fuel and air drive the pistons which turn the crankshaft .
With a rotary engine, the crankshaft is fixed, while the cylinders, crankcase and all the other bits rotate around it.
The crankshaft and connecting rods are visible through the sides of the engine block.
A timing belt or timing chain links the crankshaft to the camshaft so that the valves are in sync with the pistons.
Fuel is transformed into energy that pushes down on a piston that turns a crankshaft that turns a drive shaft.
Like in a car engine, the gas released from a manhole explosion could push on a piston and turn a crankshaft .
It comes from some of the critical wear areas; for example, the liner of the piston area, the crankshaft , or the camshaft.
Behind the engine, the crankshaft links to the propeller shaft through the thrust-bearing.
