Combustion Engine
Efficiency
The Dynamic Flow engine addresses the challenge of thermal efficiency through a two-fold strategy. Its advanced valve configuration enables optimized airflow to deliver a significant boost in thermal efficiency, reaching up to 48% across engines of varying sizes. Additionally, by applying a highly efficient Atkinson cycle that incorporates early intake valve closure, the engine can push thermal efficiency up to 75%. Because these two features are unique to the Dynamic Flow engine, they cannot be implemented in conventional four-stroke or two-stroke engine designs.

The potential impact of this technology is monumental. Compared to current combustion engines, a projected 75% thermal efficiency translates into the potential of save billions of gallons of fuel annually. This dramatic reduction in fuel consumption would simultaneously slash carbon dioxide emissions by hundreds of millions of tons per year, solidifying the Dynamic Flow engine as a true game-changer in the fight against climate change.
