This is the development of my chinese type valveless engine which you see the original version(without augmenter) in my instructable. The engine without augmenter produces a thrust of 13pounds after augmentation it produces a thrust of 22to 24pounds of thrust. PLEASE REDUCE THE VOLUME BEFORE WATCHING THE VIDEO. Engine has been placed and tested successfully over the bicycle, it pushed so hard. 14.2kg gas tank was used to test.
