Tucked away in the sea of tent booths just off Boeing Plaza at AirVenture was a real surprise: a new engine from Taiwanese company Yusimiti.
The horizontally-opposed air-cooled 4-cylinder resembles a Continental O-200 in the power section and a tuned runner intake Lycoming in the sump/intake. Resemble it might, but the Yusimiti is hardly an exact copy. Most notably are patented single-piece cylinders. That is, the cylinder head and cylinder proper are a single aluminum casting with an integral iron sleeve.
Most of the new engine’s specifications are standard fare. It’s a 4-stroke, 4-banger with direct drive and hydraulic lifters. It displaces 3.3 liters (212 cubic inches), is rated at 110 hp at 2800 rpm and runs on 95/98 octane mogas or 100LL. Installed weight is listed at 75 kg or 165 lb (with oil).
The single engine shown was wearing a carburetor but fuel injection is said to be an option. Yusimiti has an electrical component history and has fitted their engine with dual electronic ignitions.
The engine is supplied complete with carburetor, alternator, ignition, oil filter, mechanical diaphragm fuel pump and vacuum pump. List price is a competitive $25,000. There is no certification so the engine is for experimental applications only.
Castings are made in-house at Yusimiti with machining farmed out.
Yusimiti says a 3 year warranty is in the works and they are looking to sign their first US dealer. They are taking orders now at www.yusimiti.com.tw.
