The Zanzottera MZ 301 is a three-cylinder, in-line two-stroke, dual ignition aircraft engine designed for ultralight aircraft. [1] [2]

Contents

The engine was originally designed and produced by Zanzottera Technologies of Italy, but the design was sold, along with the rest of the company's two-stroke ultralight aircraft engine line, to Compact Radial Engines of Surrey, British Columbia, Canada. [2] Compact Radial Engines was then in turn acquired by Fiate Aviation Co., Ltd. of Hefei, Anhui, China in August 2017. Fiate Aviation did not advertise the engine as available in 2021. [3]

Development

The MZ 301 was developed first as a fuel injected 90 hp (67 kW) lightweight competitor to the more expensive liquid-cooled four stroke 80 hp (60 kW) Rotax 912. Later a carbureted version of the MZ 301 was developed with three Bing 54 carburetors and producing 85 hp (63 kW). [1] [2]

The MZ 301 has cylinder barrels that are Nikasil-coated. The bore and stroke are the same as the single cylinder MZ 34 engine and twin-cylinder MZ 201 and MZ 202 powerplants . The MZ 301 features electric starting and the RZ2 gearbox with optional reduction ratios of 2.18, 2.55, 2.88, 3.11 or 3.66 to 1. [1] [2]

Variants
