This just came in the mail, it has a throttle valve that works great. I can slow it down and in the video you will see how slow it will go in real time.
Hello sir Thanks for the video, Contrary to the comment below, the speed control VALVE is adding a pumping loss to the engine by constricting the communication of gas flow between the cylinders,,, and it works, this is great information for some one wondering if directly connected hot/cold cylinders have an advantage to the added unswept volume added by piping for connections and the relation to undersized tubing. thanks again
reality check tom to a significant degree, the rpms of an engine that is doing Work, are Determined by the 'feedback', from the load. consequently, an ability to vary the speed of an un-loaded engine is impressive, NOT AT ALL googletranslate
