AEROMOMENTUM AM13 AIRCRAFT ENGINE
The AM13 engine is a 1.3 liter 4 cylinder automotive engine of 100 hp converted to aircraft use. This engine is comparable in power and/or weight to the Rotax 912 and Continental O-200. Built in both upright or low profile slant versions. The upright versions are mostly used in trikes, light twins and replica aircraft that require a narrow engine package. The low profile slant version places the engine at 70 degrees from vertical to fit more conventional cowlings. Our low profile 70 degree slant version is internally designed from the factory to be mounted at an angle and this is not an aftermarket modification that may effect reliability.
All of our engines are assemble by us from all new parts. We never use any unknown JDM, used, “rebuilt”, “on condition” or other junk yard parts by any name. Why buy a used engine when you can buy all new for less.

The AM13 is the cost effective alternative to the Rotax 912, Continental O-200 and other similar aircraft engines. The AM13 is a 16 valve, SOHC, inline 4 cylinder engine of aluminum construction. Like the Rotax engines the AM13 utilizes gear reduction to provide efficient power in a small light weight package but at a low propeller RPM.
The AM13’s fuel and ignition are controlled by a FADEC system for simplicity of operation and outstanding fuel economy. At economy 55% power cruise the fuel consumption is an ultra low 0.39 lbs/hp/hr providing a fuel flow of just 3.5 gal/hr! Add to this the ability to run on auto fuel and your operating costs drop dramatically. Why suffer the high cost of a Rotax or Continental when the new choice is clear.
