The Shvetsov ASh-62 (Russian: АШ-62, designated M-62 before 1941) is a nine-cylinder, air-cooled, radial aircraft engine produced in the Soviet Union.

The ASh-62 was a development of the Wright R-1820 Cyclone that had been built in Russia under licence as the Shvetsov M-25, the main improvements including a two-speed supercharger and a more efficient induction system.

First run in 1937, licensed versions are still in production by WSK "PZL-Kalisz" in Poland (as of 2017).

Polish-built ASz-62IR engines (Polish transcription of Russian name), by WSK "PZL-Kalisz" in Kalisz, are compatible with FAR-33 requirements.

[1] The M-63 was an improved version of the M-62 with the power output increased to 821 kW (1,100 hp) at 2,300 rpm for takeoff and 671 kW (900 hp) at 2,200 rpm at 4,500 m (14,800 ft) due to a higher compression ratio of 7.2:1 and a higher redline.
