A direct drive engine arragement is one where the crankshaft, to which the pistons of the engine are connected, is directly connected to the propeller. Non-direct drive engines use a gearbox, usually a reduction gearbox, to make the propeller spin at a RPM lower than the engine's. In case of the Cessna 172, the rotational speed of the propeller (2 blade, hartzell) is the same as the engine's.
