The Zanzottera MZ 201 and MZ 202 represent a series of twin-cylinder, in-line two-stroke, dual ignition aircraft engines tailored for ultralight aircraft and motor glider applications.[1][2][3]
Initially engineered and manufactured by Italy-based Zanzottera Technologies, the entire lineup of two-stroke ultralight aircraft engines, including these models, was later transferred in ownership to Compact Radial Engines located in Surrey, British Columbia, Canada.[3] Subsequently, in August 2017, Fiate Aviation Co., Ltd., headquartered in Hefei, Anhui, China, acquired Compact Radial Engines.[4]
Development
The MZ 202 was first introduced as a lightweight powerplant delivering approximately 60 hp (45 kW), designed to compete with the liquid-cooled 64 hp (48 kW) Rotax 582. Following this, the MZ 201 emerged as a de-rated version producing around 45 hp (34 kW), intended primarily for motorgliders and single-seat ultralight aircraft requiring greater output than the single-cylinder Zanzottera MZ 34.[1][2][3]
Both the MZ 201 and MZ 202 utilize cylinder barrels coated with Nikasil, sharing identical bore and stroke dimensions with the single-cylinder MZ 34. The MZ 201 can be equipped with either a recoil starter or electric start system, whereas the MZ 202 is exclusively fitted with electric starting. Regarding reduction drives, the MZ 201 offers a choice between a belt-driven or gearbox reduction system, while the MZ 202 is supplied only with a gearbox featuring selectable reduction ratios of 2.18:1, 2.55:1, 2.88:1, 3.11:1, or 3.66:1.[1][2][3][5]
