Aviation Piston Engines & Parts

Aviation Piston Engines

A wide selection of Certified (aka Certificated) and Non-Certified (aka Non-Certificated) reciprocating (piston) aircraft engines, parts & accessories are offered for use in General Aviation aircraft and other applications. The terms "Certified" and "Certificated" are used interchangeably throughout the text below.

Although TEXTRON LYCOMING, CONTINENTAL AEROSPACE TECHNOLOGIES (formerly CONTINENTAL MOTORS) and BPR ROTAX engines are commonly used powerplants in their certificated and -non-certificated models and versions, quality non-certified  pre-assembled engines and engine kits from less known manufacturers can be supplied for use on  home built / experimental, ultra lights, light sport aircraft (LSA) and many other uses. They come in different power outputs, number of cylinders, cylinder configurations, direct drive or geared versions, fuel delivery and cooling systems and other features and specifications to cover diverse application needs of their prospective users.  Some engines have been exclusively designed and developed for aircraft (like those of LYCOMING, CONTINENTAL or  MWFLY) while others are based on conversions of automobile (car) engines for aircraft installations.

Brief information is provided below on Non-Certified engines (together with their parts and accessories) already listed in our Web Platform for Supplies and others not currently listed, which can be supplied through our co-operating suppliers.

Buyer's Guide

Buyer's Guide is also published with more analytical content of the features and specifications of different aircraft engines as reference material for current and prospective customers. Please consult our Guide and individual engine presentations for additional information.

Aviation Engines with horsepower up to 85 hp

Engines in this category include the Japanese HKS 700E 60 hp, 2-cylinder, 4-stroke engine, Austrian ROTAX UL DCDI MOD.99 65 hp 2 stroke, 2-cylinder and their bestselling 912 UL 80 hp 4-stroke 4-cylinder engines and Australian JABIRU 2200 4-cylinder engine rated at 85 hp. ROTAX and JABIRU also offer motors in the medium horsepower range of 85-160 hp. 

In addition, 2 and 4-cylinder, 4-stroke VW horizontally opposed direct drive, air cooled engines converted to aircraft use are offered from US HUMMEL ENGINES with rated horsepower  28 – 85 hp while respective engine kits like those of US GREAT PLAINS AVIATION SUPPLY in front drive-direct drive, flywheel drive and reduction-drive configurations and Sonex Aircraft AEROCONVERSIONS 80 hp AeroVee 2.1 are also available.

Aviation Engines with horsepower over 85 hp up to 160 hp

 ROTAX plays a significant role in this market segment. Their 912, 914 and newer 915/916 series of aircraft engines are relatively lightweight, compact engines with air-cooled cylinders and liquid-cooled cylinder heads. These engines have been designed for higher rpm than their LYCOMING and CONTINENTAL counterparts with a built-in propeller speed reduction unit (gearbox) to optimize propeller rpm. ROTAX engine portfolio includes their carbureted 80 hp 912 UL (mentioned above), the 100 hp 912 ULS as well as the turbocharged 914 and their newer 915 iS 141 hp and 916 iS  160 hp powerplants. Certified FAA and JAR/EASA versions models are also offered and include: ROTAX® 912 F, 912 S, 912 A, 912iSc2/912iSc3, 914 F2/914 F3, 915 iScA/ 915 iSc C24, 916 iScA/ 916 iSc C24.

Non-certified powerplants are also offered as alternative to ROTAX® engines  by different engine builders such as the Italian MWFLY, the Australian JABIRU or competitive priced automotive engine conversions for aircraft use by the US manufacturers AERO MOMENTUM , VIKING, Sonex AEROCONVERSIONS. 

MWFLY SPIRIT 4-cylinder/4-stroke horizontally opposed (boxer type) aeronautical engines have been developed specifically for use in light aircraft and they can be used on LSA and experimental single-engine or twin-engine airplanes and other aircraft (STOL, helicopters, gyrocopters, hang gliders, seaplanes and drones). These engines feature 100% liquid cooled cylinders (compared to liquid and air-cooled cylinders of their ROTAX® counterparts) with electronic ignition and fuel injection with dual ECU computers as standard. Their two SPIRIT SKYLINE and REDLINE engine lines include several direct or geared drive transmissions (depending on the model) developed respectively for touring and performance flying. SKYLINE engines deliver 100, 122, 135 & 140 hp while their REDLINE counterparts deliver 115, 135 & 160 hp. The 135 and 160-hp direct drive engines are high-rpm units for helicopter use only.

JABIRU bestselling six-cylinder 120 hp 3300 engine is another option due to its light weight, simplicity, affordability and a significant power-to-weight ratio. Like their 85 hp four-cylinder 2200 engine (mentioned above) construction relies heavily on aluminum through the crankcase and cylinders—silicon carbide and nickel coated—for low weight and rapid heat transfer. Both are simple engines in design and operation. A single Bing slide-type carburetor, mechanical fuel pump and inductive ignitions are used along with fixed-timing ignition distributors. Both the alternator and inductive ignition are integral to the engine designed to work as long as the engine is rotating.

AC Company (AC Aero) in Japan offers Combined Cycle Technology (CCT) Higgs Diesel engines operating on JET A, diesel and gaseous fuels such as hydrogen. Apart from aviation these engines can be used on drones, generators, compressors, marine or land vehicles, military and other space / weight single fuel restricted designated use applications. Their FALCON FL150 engine, weighing only 147lbs. (67 kgs) has a power output of 115 hp in naturally aspirated (NA) and up to 130 hp in fuel injection (FI) engine versions. With a service ceiling of 30,000′ the FL150 engine is ideal for LSA, kitplane builds, drones and other applications. Various other models of higher horsepower compete with engines of other manufacturers in the next category.

Belgian manufacturer D -MOTOR also offers 4-stroke side valve (flathead) boxer engines featuring multipoint fuel injection, electronic ignition, and liquid cooling. Their two models, the 4-cylinder LF26 and the 6-cylinder LF39 provide a maximum continuous power of 93.68 hp (58 Kgs) and 125 hp (78Kgs) at 3100 rpm respectively. Mostly used in helicopter and drone applications due to their light weight, low MoGas consumption, low rpm (low noise) and their nearly flat torque capabilities. These engines are sold to OEM aviation manufacturers only.

Lower priced automotive engine conversions for aircraft use are also offered either as pre-assembled engines or engine kits by US manufacturers including different engine models from AERO MOMENTUM, VIKING and SONEX AEROCONVERSIONS 100 hp AeroVee Turbo engine kit.

Aviation Engines with horsepower over 160 hp

For power outputs exceeding 160 hp, CONTINENTAL Titan and LYCOMING Thunderbolt non-certified engines are popular among aircraft builders. 

CONTINENTAL Titan engines with power ratings from 174 to 195 hp are offered as experimental derivatives of the four-cylinder Lycoming parallel-valve architecture engines in the popular 340 and 370 displacements but with numerous upgrades. 

LYCOMING non-certified engine solutions for experimental aircraft are also offered and include their standard experimental engine models and their premium Thunderbolt product lines, the company’s brand of high performance, built-to-order powerplants for these aircraft. Instead of being made on an assembly line, each Thunderbolt engine is hand-built. Also, most of these experimental-category engines contain performance-enhancing modifications such as high-compression pistons, cold-air induction, and electronic ignition designed to increase horsepower and flight efficiency. Each LYCOMING Thunderbolt engine is a non-TSO version of a genuine Lycoming engine model, factory built and tested which is further customized & personalized through the selection of several popular options of fuel systems, ignition systems, performance enhancements and finishing options. All Thunderbolt engines feature a balanced rotating system within 0.5 gram (connecting rods, pistons, piston pins), ported and polished cylinders, and customized paint options. Thunderbolt lineup covers the full spectrum of Lycoming familiar O-235, 320, 360, 390, 540 and 580 cubic inch models (from the four-cylinder O-235 to the eight-cylinder IO-720) although the IO-390 and IO-580 are the most popular. Of the engines offered, all use parallel valve cylinders except the 390 and 580, which employ angle-valve cylinder heads. That makes them more efficient and powerful, but also heavier and more expensive.
