By heat soaking do you mean that they overheat from being in close proximity to the motor? It seems that you could solve that by moving the actual sensor onside the valve covers with a small pushrod (ok, ok, I know, ancient technology to solve a new problem!!!)94 Daily Driven 4.6L said:Seriously though, the latest problem yet to be overcome in the "camless" engine is the heat soaking of the electromagnetic valve actuators. Have they solved that problem yet?
I, too, had been thinking about "camless" engines in high school (late 80's for me). I even drew up designs (more like doodles). The ideas I had were based on electromagnetic actuators. The biggest problems I could see with the whole concept were that the solenoids would have to be very powerful (and therefore draw a lot of current) to open and close the valves at the speeds required in an engine and the noise factor. On a 16-valve, four cylinder engine you'd have 16 large, powerful solenoids clicking away. Lotsa noise.94 Daily Driven 4.6L said::rofl: I've been discussing that concept with a buddy of mine since high school!!! (late 70's/early 80's) Do you want me to post the drawings I have of the "port shaft" that I was working on... :leftright
