Dear Friends, Hope everyone is having a great time. I am from India, work as a biologist. I have NO engineering background whatsoever, but like to pass my time, tinkering with my honda CBF 150. I have this idea for a new 'Type' engine, but dont know if it would work. My idea is to combine a cylinder/Piston assembly (Suck/compress fuel air mixture) and pass it to a parallel chamber for ignition/exhaust. The pressurized escaping exhaust spins the flywheel. Of-course, plenty of valves are required throughout to minimize leaks and blowouts. I have many questions here, 1) Has this been previously tried ?. Any pictures, models, links ? 2) what are the short comings?, benefits ? 3) Would anybody from this group be interested in making a working miniature model. I am curious to know how my idea would look like. Thanks in advance. I hope to read your valuable comments. Cheers.
