Our Stirling engines feature our innovative and patented TrueCycle technology, developed at Ontario Tech University. This makes our engines capable of following the actual Stirling cycle, which previous “Stirling engines” were not able to do. Therefore, we can achieve efficiencies much higher than previous engines.
How did we improve the Stirling engine?
Non-sinusoidal motion
To follow the Stirling cycle, an engine must be capable of non-sinusoidal motion. Traditional engines use a crank shaft, which produces sinusoidal motion. The blue shaded area in this plot shows the work lost during each rotation of the engine when sinusoidal motion is used. We patented our TrueCycle method of accomplishing non-sinusoidal motion in our Stirling engines, which produces much higher efficiencies.
Sub-regenerators
In a Stirling engine, the regenerator stores the heat between the hot and cold chambers, and is crucial for achieving high efficiencies. Single regenerators can only achieve 50% effectiveness, which diminishes the efficiency of an engine. We have developed regenerators composed of numerous sub-regenerators in a new design that can achieve over 95% effectiveness and increase the overall efficiency of our Stirling engines.
