Based in Stuart Florida, USA we find another car engine conversion. The company is called AeroMomentum and is run by Mark Kettering. They manufacture a low cost, factory new car engine converted for aerospace applications with FADEC / fuel injection and a typical specific fuel consumption of 0.39 lbs/hp/hr.
The engine is based on the well proven Suzuki G series engine, made from all new parts and is build up in Stuart, Florida. Every engine is tested and run with a propeller before shipment to the customer.
At the moment the company is manufacturing four engine models: the AM10 75 hp three cylinder, the AM13 100 hp four cylinder, the AM15 four cylinder with 117 hp and the AM20T a turbo charged model with 260 hp. All engines can be painted in different colors to suit your aircraft and personal taste.
These engines are being produced for boats and airboats since 2008 and the company has a lot of experience in maintaining and operating them.
AeroMomentum engines are 3 or 4 inline cylinders, precision cast aluminum block and head, steel cylinder sleeves, 4 valves per cylinder, single overhead cam, toothed belt cam drive, fixed valve timing, plenum tuned intake system, tuned tubular exhaust system, 2.5:1 ratio PSRU to drive the propeller.
The oil pump is direct crank driven gerotor (trochoid), solid cast steel crank, forged connecting rods, Bosch FADEC engine control system, dual coil ignition, sequential fuel injection, knock sensor, light weight 40 amp alternator with an optional 70 amp version and hemispherical combustion chamber.
The crankcase is CNC machined from aerospace aluminum alloy billet. The gears and shafts are forged and finished to AGMA aerospace standards. Coupling the engine to the gearbox is a German made Guibo rubber dampening donut that also is designed to last to engine TBO.
The PSRU uses an all gear design with the same TBO as the engines. The only service is periodic oil changes, no belts or other expendables. It is designed for 4 cylinder engines up to 210 hp and utilizes oversize gears and oversize bearings for extreme durability and reliability. The propeller shaft is hollow allowing for mechanical propeller pitch adjustment. The hub is drilled for standard Rotax, high power Rotax and optional SAE-1 propellers.
For the AM15 we have a firewall mount illustration available, hover the mouse over the image for a more easier to read size.
