The Rotax 532 is a
two-stroke
A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a power cycle with two strokes (up and down movements) of the piston during one power cycle, this power cycle being completed in one revolution of t ...

Design
The 532 features liquid-cooled cylinder heads and cylinders with a rotary valve inlet. Cooling is via one or two externally mounted radiators. Lubrication is by use of pre-mixed fuel and oil at 50:1. The 532 has a single

The Rotax 532 was replaced in production by the improved
Rotax 582
The Rotax 582 is a two-stroke, two-cylinder, rotary intake valve, oil-in-fuel or oil injection pump, liquid-cooled, gear reduction-drive aircraft engine manufactured by BRP-Rotax GmbH & Co. KG. It is for use in non-certified aircraft operati ...
engine design. The 582 increased the cylinder bore from the 532's 72 mm to 76 mm. This increased the displacement from 521.2 cc to 580.7 cc, an increase of 11%. The increased displacement had the effect of flattening out the 532's torque curve and allowed the 582 to produce useful power over a wider rpm range. Reliability over the 532 was also improved.
