About Tavernier Power Dynamics Inc.
Meet Jonathan Tavernier
Jonathan Tavernier is the visionary inventor behind the patented TAV Engine and the driving force of Tavernier Power Dynamics, Inc. A graduate of the Diesel Institute of America in Maryland, Mr. Tavernier spent 15 years operating Freightliner trucks on national interstate routes, gaining firsthand experience with the strengths—and limitations—of traditional heavy-vehicle engines. After taking an early retirement in 2007 due to severe glaucoma, he shifted his focus toward innovation, ultimately securing two U.S. patents for his groundbreaking tubular-valve internal combustion engine design: US 10,711,667 B2 (July 14, 2020) and US 11,035,331 B2 (June 15, 2021). Today, his work continues to push the boundaries of efficiency and performance in the future of large-vehicle power systems.
Innovative Advantages of the Tavernier Engine
The patented engine design developed by Jonathan Tavernier introduces several groundbreaking advantages for the trucking and large-engine industries. By eliminating the traditional camshaft, poppet valves, and springs, the system significantly reduces vibration and decreases unnecessary torque on the engine. Instead, it utilizes rotating tubular valves with precisely engineered portals that align flawlessly during each stage of the combustion cycle—intake, compression, ignition, and power—creating a smoother, more efficient, and more reliable engine performance.
Unique Advantage of Tavernier Tubular Valve Engine
Superior engine compression braking—commonly known as Jake braking—uses changes in the piston’s compression cycle to slow the vehicle’s crankshaft. While this technique is essential in the trucking industry to prevent brake burnout on heavy loads and long descents, current systems are notoriously loud and contribute to increased emissions, leading many populated areas to restrict their use. The Tavernier engine introduces a groundbreaking solution: a quiet, cleaner, and far less polluting compression-braking method that delivers the same vital control without the noise or environmental impact.
The Market for This Innovation is Massive
The market potential for this innovation is enormous. The interstate trucking industry and broader supply chain together approach a staggering $1 trillion in economic activity, with individual engines often costing $30,000 or more. Despite advances in electric technology, electric engines have yet to gain meaningful traction in the heavy-duty trucking sector, leaving a wide-open gap for more efficient internal combustion solutions. Beyond trucking, the Tavernier engine design holds promise for buses, rail systems, mining and construction vehicles, and even the shipping industry—making its commercial reach truly expansive.

The next objective is to advance the technology to a full proof of concept and develop a working prototype that demonstrates the engine’s capabilities in real-world conditions. Once validated, the plan is to license the patented design to major engine manufacturers for large-scale production and industry adoption. Those interested in seeing the early concepts can view the “Tavernier Valveless Engine” demonstration on YouTube.
