Kinetic and Potential Energy in Valvetrain Motion

instead of getting this is static valve motion no deflection no twisting as you make it go back and forward these ramps get steeper and the energy into the spring gets gets greater yeah when you think about a cam design every bit of energy that I put in this system we talked about how a Pro Mod will launch well you can imagine this is kind of like zero to 100 to zero and then back again because once we launch on the opening ramp we're coming up here and all of this velocity is kinetic energy all of the kinetic energy in this opening side the steeper we make this the more the valve spring has to catch right so all of the you've got potential area of the camshaft here kinetic energy in the valve train here and then potential energy in the valve spring here then the potential energy of the bowel spring has to be released to create kinetic energy of the valve here and then that goes back into potential energy of the camshaft there so it's a big energy dance if you imagine it and if anything starts deflecting a push rod deflects or Rock arm deflects the valves the the cam itself starts getting pulled back and shot forward all of that is more energy in the system so the more we can control that the closer we can get with our Dynamic motion Dynamic motion to our static motion if you get it wrong and it looks like you you know tried to jump the shark up here you could Evil Knievel Caesar's Palace Landing down here you call that valve bounce and it's really bad and that's what the spencerons are great for yeah what happens here is you can imagine if if if we lose control here and come on up if you think this was interesting send it to one of your friends who you would think might think is interesting too because odds are the system that you know if whatever suggest videos to people's probably not going to show this one to somebody so it's up to you guys you die hards to help it grow and we appreciate you for doing that then it's going to go to Coal Bond it's going to come across then it's going to shoot it back down it'll come back and it'll hit in this area and reflect a little bit and then it bounces back up and then comes back down well with RPM this this this node right here that we jokingly call plumber's crack it starts on this side and it works to this side is this works all the way back to the bottom it is totally out of control the other thing is this is when the spring is most stressed is here over the nose so if you have the crash when the spring is most…
