Facing acute climate and environmental concerns – and anticipating order-of-magnitude increases in electrical power demand as the trend toward vehicular electrification gains momentum — manufacturers, consumers and investors are asking…
Where is the world’s next-generation advanced engine design – smaller, lighter, more powerful and efficient, fully scalable, capable of producing cleaner and lower carbon footprint power, and buildable in high volumes at low cost?
Lumenium proudly introduces its answer —
Our Advanced IDAR (Inverse Displacement Asymmetrical Rotational) Engine
- A critical ingredient in the complex quest for a realistic net zero carbon future
- The ideal power source for hybrid electric power systems
- A key component of localized, smaller-scale primary power generation to bolster the power grid as electrification demand – especially from electric vehicles — grows exponentially
- Adaptable to newly developing carbon-neutral fuels AND emissions-free hydrogen combustion
IDAR’s strategically patented architecture utilizes unique-to-IDAR interaction of convex and concave shapes. Neither piston nor rotary based, Lumenium’s advanced technology IDAR Engine is simple, durable and cost-effective to manufacture, and signals a transformation in engine technology that is ripe for accelerated implementation in a climate-challenged world.
IDAR Engines have a power density well beyond existing engines – in other words, equivalent horsepower and performance in a dramatically smaller and lighter package.

IDAR’s concentrated power density will allow a 20 kilowatt generator to be sized more like a small residential HVAC unit than a large storage locker…
…and a large 125 KW generator to be sized more like a kitchen cabinet.




IDAR fully burns all injected fuel by low temperature combustion, reducing harmful emissions – especially NOx – and minimizing complex and costly after-treatment systems.
Lumenium’s state-of-the-art computational fluid dynamics (CFD) modeling shows the IDAR Engine to be highly adaptable to clean and carbon-neutral fuels, including emissions-free hydrogen.


IDAR is ideally suited – by size, shape, power density and cost – to hybrid electric platforms and planned multi-source power generation systems, including advanced microgrids.
IDAR Engines can be scaled by diameter or width in single power modules of varying displacements…


Or by stacking power module “slices” to create an engine family of varying displacements, simplifying maintenance, spare parts provisioning and repairs. Power module slices may be combined to achieve engine displacements from 250cc to 11 liters, and from 5 horsepower to 750 horsepower.


And modularized IDAR-powered 125KW generator units can be aggregated into “plug-and-play” power clusters generating localized power of One Megawatt or more, either in stationary or trailer-portable configurations.
IDAR has less than half the parts count, and can be manufactured at less than half the cost, of a piston engine of comparable power output, fostering a quicker transition to cleaner power through accelerated retirement of current engine technology.


The IDAR M21 diesel combustion research engine, running without a muffler and with no other sound attenuation, has shown itself to be quieter than existing technology engines and significantly lower in vibration.
IDAR is in accelerated pre-production development today, working with various Original Equipment Manufacturers toward initial licensing by next year. Lumenium offers integrated design and development by fabricating its own parts, and assembles and tests IDAR Engines in its Fredericksburg, Virginia engine lab facility.
Lumenium is working with leaders in the field of 3D metal printing, taking advantage of the latest advances in additive printing technology to ensure that the IDAR Engine will be largely printable by the time of commercial production.
The IDAR engine adapts to a wide range of applications, including generators, automobiles, trucks, off-road construction, forestry and agricultural equipment, as well as watercraft, aircraft and drones.


Supplementing our multi-faceted internal capabilities, Lumenium maintains strong and active working relationships with renowned independent engine design firms and advanced simulation experts, as well as with the combustion engineering division of a celebrated U.S. national laboratory.
Lumenium also has entered into a formal joint development relationship with one of the world’s largest engine OEMs, and is in technical discussions with a dominant international automobile manufacturer, as well as with other significant players in the power and energy field, all with a view toward developing entire families of IDAR engines for a wide range of applications.
