![]() This gives the connecting rods a more favorable angle during each power stroke, which reduces side loading on the pistons and, in turn, improves efficiency. Viking cylinder bores are offset by 6.0 mm from the crankshaft to help reduce piston-sliding friction. Special low-drag piston ring design, yet high compression.Įach journal on the forged-steel crankshaft is micro-polished to reduce internal friction. Low-friction oil seals in the engine and Viking propeller speed reduction unit. Low viscosity oil (0W-20) further reduces friction.Ī special 2-stage oil pump relief valve reduces friction when maximum oil pressure is not needed. This also enhances the long-term wear characteristics of the Viking engines. Plateau honing is a 2-stage machining process that uses two grinding processes instead of the more conventional single honing process. Plateau honing further lowers the friction level between the pistons and the cylinders by creating an ultra-smooth surface. The result is reduced overall friction as the pistons move within the cylinder bores. The outer skirts of the Viking lightweight aluminum pistons feature a low-friction coating applied in a unique pattern. Internal Engine Friction Reduction Technology The reduced cost is simply due to that the Viking engines are based on the latest mass-produced Honda car engines. The Viking engines generally cost half the amount compared with other brands, there is sometimes a misnomer that you somehow end up with an inferior engine. Viking engines with world class “Internal Friction Reduction” engine technology.Īs a leading provider of engines to the Experimental Aircraft builder community, it is important for us to convey to our existing and future engine owners, what exactly they own, or are about to own if purchasing a Viking Aircraft Engine. Viking continues to be the most affordable engine option without sacrificing quality or performance with engines at $9,995.00.Ī lot of new companies will state compatibility and longevity numbers with no real flight hours and evidence that it does more than just "fit" Do your homework, talk to real customers, and be safe in your decisions. Most of all to see you fly successfully and be happy with the results. Viking is always available to assist you in your installations, flights and problem solving along the way. Check out our forum and website and see for yourself.Īlways ready to ship - next day, no waiting 6 or more months to receive your engine and a full FWF kit. Your getting PROVEN results, with customers who have hundreds of hours on their aircraft. We install our engines and fly them all over the US Why Choose Viking? We built the first Zenith Cruzer and the first customer Zenith Super Duty. We are in it for the love of aviation, flying and all things undiscovered. Here at Viking, we spend every waking moment thinking about torsion dampers, radiator efficiency, power to weight ratios, and all sorts of things related to engines and flying machines, we love what we do and never think of it as work. No 1990’s new blocks or hand assembly just exactly the technology you would expect from buying a modern showroom car. ![]() ![]() Viking uses the absolute latest available engine technology for their aircraft engine conversion. Our Business Model and Why it's Important Every part is OEM Honda / Mitsubishi, nothing is new aftermarket from unknown origins. We don't change vital engine parameters around and claim we have different models. We don’t claim that we can outsmart either company when it comes to the design of any internal running component of these engines. When customers want the information about where there engine core came from and how many miles it had - we have all that documentation readily available to show.Ĭompanies like Honda and Mitsubishi have spent millions of dollars refining and testing. We start with the most up to date year engines with super low mileage, derived from fender benders across the US. Selling used engines has always seemed to be a controversial topic, it is time to dig a little deeper into the reasons we offer both used and new. Why we choose OEM built, tested and proven engines over building outdated technology from decades old replacement parts.
