This is a graduation project for engineering students ,they call it the RIICE , Rotational Impulse internal combustion engine.
Even though their engine never got to do internal combustion. but nice math work.
The nice thing about this engine is that it was build within a budget of 1500 dollars.
The best thing about this engine is that even thow these guys never mention me or any other reference for their idea , they where able to understand the idea of the “Mechanical Diode being TOO LARGE”. and they have solved it .
By them using one way Bearings , they where able to Reduce the SIZE and COAST extremely effectively .
I Think that all Cat and mouse engines from now on will use the same principle
Here is their final report pdf
