The Zanzottera MZ 301 is an inline, three-cylinder, two-stroke aircraft engine featuring dual ignition, specifically engineered for use in ultralight aircraft.[1] [2]
Initially crafted and manufactured by Zanzottera Technologies based in Italy, the design for this engine was later acquired by Compact Radial Engines located in Surrey, British Columbia, Canada, along with the company's complete range of two-stroke ultralight aircraft engines.[2] Subsequently, in August 2017, Fiate Aviation Co., Ltd., headquartered in Hefei, Anhui, China, took over Compact Radial Engines. As of 2021, Fiate Aviation did not list this engine as part of their available product lineup.[3]
Development
The MZ 301 was initially introduced as a lightweight, fuel-injected powerplant delivering 90 hp (67 kW), intended to compete with the pricier liquid-cooled four-stroke 80 hp (60 kW) Rotax 912. Subsequently, a carbureted variant was developed featuring three Bing 54 carburetors and rated at 85 hp (63 kW).[1][2]
Its cylinders are coated with Nikasil for enhanced durability. The engine shares identical bore and stroke dimensions with the single-cylinder MZ 34 and the twin-cylinder MZ 201 and MZ 202 models. The MZ 301 includes an electric starter and incorporates the RZ2 gearbox, which offers optional reduction ratios of 2.18, 2.55, 2.88, 3.11, or 3.66 to 1.[1][2]
