Project engines are comprised of running prototypes that have gone through a varied amount of testing, often rigorous. Many of our prototypes are available for design purchase or investment. With appropriate funding we are confident that these projects will come to be fully realized and after the final steps of durability and emission testing, ready for fabrication. With an established partnership, you and AED can take our optimized prototype engine(s) from the lab to the production line.
Eco-Diesel 22T and 24TS
4-cylinder, 4-valve all aluminum direct injected turbo/supercharged diesel engine. This engine was built from converting the GM high performance (260 hp) Ecotec gasoline engine to an advanced diesel variant using commercial-off-the-shelf (COTS) Bosch common rail fuel injection, high efficiency VNT turbocharger, and custom electronic engine management.
It features variable compression ratio (variable valve timing) with brake thermal fuel efficiency over 42%; high power density (approx. 360 lbs) and low manufacturing costs.
The 22T and 24TS engine have many potential military and commercial applications; it would make an excellent diesel electric hybrid.
Current Stage of Development:
Dyno tested and developed. Ready for durability and emission testing.
Leo-Diesel 69T and Leo-Diesel 71TS
The 69T and 71TS are high power density diesel engines based on the COTS GM LS Series production truck and high performance (638 HP) gasoline engine. This advanced high power density, fuel efficient engine (projected 42% brake thermal efficiency) will weigh approximately 40% of most contemporary diesel engines with the same HP.
These could be produced as new engines or repower of military and commercial vehicles, marine, or industrial.
Current Stage of Development:
Concept model hardware stage, being assembled for dyno testing. Contact us for more information.
3.6L 4-Cylinder Direct Injected Commercial / Industrial Engine Series
Current Stage of Development:
Dyno and vehicle tested. All intellectual property (designs, drawings, testing) complete. Ready for preproduction prototyping and manufacturing investment.
AED designed and built prototypes of a new line of advanced direct-injected diesel engines. This series includes engines which are naturally aspirated, turbocharged, and turbocharged/after-cooled. These engines are capable of sustained operation at 3300 rpm. Designed for manufacturing in China and India.
This new engine series incorporates innovative, known, and forward-looking advanced technology design features to ensure the engines meet or exceed today’s market needs, but also allow growth to provide dependable world market power well into the future. A highly turbulent re-entrant combustion chamber combined with intake port swirl and high pressure fuel spray system was incorporated. Simple design for easy manufacture.
Possible applications would be trucks, medium sized buses, industrial platforms, construction vehicles, and marine propulsion.
800 to 1600 cc, 30/140 HP V-Twin Turbo Diesel
Based on the design and operation of AED’s first generation biofuel turbo diesel motorcycle engine powering a 1988 Harley Davidson motorcycle, this
2nd generation series of engines employ the latest COTS state-of-the-art common rail fuel injection, electronic engine management, and other components.
This engine can be designed and configured for a variety of products and applications: automotive, motorcycle, ATV, lawn and garden, and commercial / industrial.
Current state of development:
Completed development of a motorcycle demonstrator. Contact us for more information and investment options for second generation of the V-Twin turbo diesel engine.

Completed heavy fuel burning engines that incorporate advanced and innovative technology. The following engine designs and prototypes are not available for purchase and/or investments.
3.0L Diesel Opposed Piston Two-Stroke
This engine was created from Detroit Diesel Co.'s production 92 series components to the maximum extent possible. It incorporates a production Bosch electronically controlled common rail fuel injection system which is used on the GM 6.6L Duramax diesel V8. The ECU was custom designed and built by CSi, providing independent control of the two injectors, electronic control of a dry sump lubrication system, cooling system, and supercharger in series with a VGT.
750cc, 2 Cylinder Heavy Fuel Fire Pump
As the prime contractor to the U.S. Navy Sea Systems Command, AED, using commercial-off-the-shelf (COTS) components, designed, tested and developed a 2-cycle, 50HP, jet fuel burning fire pump with the following features:
- Direct fuel-injected
- Spark ignited
- Heavy fuel burning
- Used to power Navy shipboard 250 gpm fire pump
6 prototypes were delivered to the U.S. Navy.
JP-5 Converted 50 HP Outboard Engine
As a prime contractor to the U.S. Navy Sea Systems, AED incorporated the advanced direct fuel-injected, spark ignited combustion technology developed within the Navy Heavy Fuel Fire Pump project in converting a commercial base outboard engine to a hand-starting operational outboard.
Three tested prototypes were delivered to the U.S. Navy.
Heavy Fuel Burning UAV Single Cylinder
Under contract to U.S. Navy SOCOM, AED designed, tested and developed prototype single- and two-cylinder lightweight high powered 2-cycle UAV engines burning Jet Fuel. The engine employed electronically controlled direct fuel-injection, and stratified combustion to start and operate from idle to full throttle. The prototype was based on commercial gasoline engines.
