The Borzecki 2RB is a Polish air-cooled, four-cylinder, horizontally opposed, two-stroke, piston engine designed and built by Jozef Borzecki for use in motor gliders. First bench tested in 1970 the 2RB can be used in both tractor and pusher configuration, and the {{convert|24|hp|kW|0|abbr=on}} engine was first flown in 1972 in his own design motor glider, the Borzecki Alto-Stratus.
