Most engine's intake valve opens before top dead center. The exhaust valve opens well before bottom dead center. There is a period of time (overlap) when both valves are open. My thoughts are to shoten the duration on the cam and take advantage of a more complete burn. Also I would expect the engine make more torque at a lower rpm and would not need to rpm as high. You would think there would be a less chance of a backfire as well.
I'm sure mr. Meyers had a reason for using an aircooled engine, can anyone help me understand if there was a reason other than cost?
Hey guy's I'm new to this site, very intrested in hho. My background is in performance, race and marine engines. My question is has anyone changed cam/valve timing to work with hydrogen? Im wondering if the valve overlap could be decreased to enhance power output. Most engines I've seen running on hho don't have any load on them. Ideling or higher rpm with no load.
I'm working on a 2.5 hp single cylinder engine that I would like to convert over to hho. I welded and reshaped the combustion chamber and moved the spark plug location for what I think would be optimal. The next step is to change the cam timing. Any thoughts ?
