Template:Short description Script error: No such module "Unsubst". Template:Use Canadian English
The König SC 430 is a three-cylinder, two-stroke, single ignition radial aircraft engine designed for powered paragliders and single place ultralight trikes.[1][2]
The engine was originally designed and produced by Dieter König of Berlin, Germany. The design was sold to Zanzottera Technologies of Italy and then sold again, along with the rest of Zanzottera's two-stroke ultralight aircraft engine line to Compact Radial Engines of Surrey, British Columbia, Canada.[1][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 SC 430 is a unique three cylinder radial engine that is very compact and lightweight at only Script error: No such module "convert".. The engine features single capacitor discharge ignition, a single Bing 49 diaphragm type carburetor and rotary valve induction. When last built by Compact Radial Engines it was currently offered without a reduction drive, although when Zanzottera built it a 1.75:1 cog belt reduction drive was available. Starting is electric starter only and a recoil starter is not an option.[1][2][4]
Earlier versions produced Script error: No such module "convert". at 4200 rpm with a slide-type carburetor and reduction drive. The Compact Radial Engines version is rated at Script error: No such module "convert". at 4200 rpm. Time between overhaul is rated as 300 hours.[1][2][4]
The SC 430 shares the same bore and stroke as the larger four cylinder König SD 570 radial engine.[2][4]
