Lightweight and Simple

A single-body design combines the engine and generator into one seamless system, reducing weight and eliminating unnecessary complexity.

High Efficiency

Our embedded design eliminates friction and ensures every component is optimized to work together, maximizing performance.

Cost-Effective

With only half the parts of traditional systems, the Theta Engine drastically cuts production and maintenance costs.

Versatile and Customizable

Designed to fit a range of applications, including range extenders, on-board generators, standard generators, and CHP systems, the Theta Engine is tailored to meet unique customer needs with support for diesel (HCCI) and hydrogen (spark ignition).
