Avadi Engines launches revolutionary internal combustion engine

Avadi Engines of Washington State is launching a new type of engine that they believe will have a significant impact on the $4 billion internal combustion engine industry.

The Avadi MA-250 uses a unique, patented motor design that produces over 15 horsepower and nearly 22 foot-pounds of torque. Named after inventor, master machinist and engine designer Michel Arseneau, the Avadi 250cc engine also achieves a thermal braking efficiency of over 40%, one of the highest figures ever for a production engine.

Smaller, lighter, more efficient… and less impactful on the environment

The MA-250 was created using a minimalist approach and revolutionary design principles. By rethinking the fundamental function of how an engine works, Arseneau and his team have dramatically reduced the number of parts used in traditional engine designs. The result: a light, efficient, compact and powerful motor with a much gentler environmental footprint.

My goal is to create an engine that will benefit the environment. I had the idea for the design about 20 years ago,said Arseneau. “TThe goal was to reduce emissions. Also, make something simpler, easier to use and cheaper.

Not easy

While the design concept is brilliant, translating it from a drawing into a working prototype was no small feat, according to CEO Landon Wilkinson:

This engine is revolutionary in both form and function. It’s about half the weight and nearly double the horsepower of comparable production engines. It works through mechanical functions that have never been combined in this way. Michel has extensive experience in machining, which allowed him to carry out most of the engine R&D with little assistance,” he adds.

It is estimated that over 50,000 hours were invested in the design and machining of this engine. Vice President of Program Development Dale Renner shares an in-depth look at the creative process:

Everything inside the crankcase rotates, although it has nothing to do with a rotary engine that many people are familiar with. It still uses an ordinary plunger. The cylinder rotates, the piston rotates, and the piston is connected to two connecting rods that work together like scissors. They are connected to a pair of gears which replace a traditional crankshaft, one of the heaviest components of a traditional engine. The piston and its rotating lower assembly are directly connected to the output shaft, much like a differential.

On a mission

While electric motors are the subject of a lot of press today, the fact remains that the widespread adoption of things like electric cars is still a long way off. More recently, Toyota announced an investment of over $400 million in US-based production facilities for its venerable 4-cylinder gasoline engine. This from the company that dominated the electric vehicle production industry with its popular Prius. Toyota and the industry as a whole have a clear view of the challenges of electric vehicles such as the imminent environmental impact of production, a realistic charging infrastructure and the long-term viability of sales, operation and service. disposal of electric vehicle components.

The Avadi team sees the opportunity to co-exist with the development of user-friendly electric vehicles…and the smaller, lighter, fuel-efficient Avadi MA-series engine is a strong candidate for both convenient on-board charging and viable autonomy. extension.

Few significant changes have been made to the internal combustion engine since it was widely adopted nearly 100 years ago. We believe our engine design will address a key transition need, as pressure increases for more efficient, economical and low-emission power requirements,adds Wilkinson.

Avadi also plans to increase the size of its engines to meet the needs of different markets and introduce a larger diesel model in the future. The company also plans to test the engine with hydrogen and as a compressed air engine, which powers the engine with short bursts of air rather than spark-ignition combustion.

All forward moves count

Founded in 2014, Avadi Engines has successfully built and tested several working prototypes over the past few years. As R&D continues, the team has been busy forming a number of partnerships with companies interested in testing their engine on various end-use platforms.

Since debuting at the 2022 CES Technology Trade Show in Las Vegas, Avadi Engines has had over a million interactions on social media platforms as well as engine demos with various organizations. They have also received patents in the United States, Canada, Singapore and Taiwan in the past year.

While development is ongoing and additional funding will be required to make the engine commercially viable, the Avadi Engines team believes the time is right to share their story with the world as they seek both individual investors and strategic partnerships with companies that have specific needs. that they might encounter:

The MA-250 can replace virtually any device or piece of machinery that uses an internal combustion engine – from lawnmowers and scooters to automotive and aviation to freighters and locomotives,Renner says. “We are in talks with a confidential government defense contractor who is interested in our engine for their new UAV/drone.
