If you look closely, you can see that if a individually controlled drum were to be provided for each cam lobe/valve then you could have an infinite adjustment for the valve train. it looks very easy to implement.
In a four valve design, one set of valves could be shut off at low rpm or at high efficiency mode while the working valves could operated with more opening. This would give you what DSI attempts to do.
OTOH, if you want it power, then you'd go for all valves working.
Also, implementing VCM would a slam dunk as well.
Indeed, since the drum rotates, it doesn't require a lot of reciprocating mass so the system can operate very fast.
Hmm.... you could have an almost infinitely adjustable system, with redline only controlled by the springs and valve mass.
They oughta put a big rotaging RED knob on the dash. Fully conterclockwise, at 0, it'd be economy. Fully clockwise ( 11, of course, NOT 10) you'd have a full blown race motor.
Dang it..... this is soooo simple. Goodbye to complex chains and idlers to implement iVTEC. Goodbye complex, multi lobe cams.
Honda has once again leapfrogged the competition by about ten years.
See? like I told you all... HMC is ten years ahead of the competition when it comes to engine design.
Dang it.... this is gonna piss off a lot of other manufacturers.
Now I can see the aftermarket working on drum follower designs instead. Hmm... it looks like changing those fellows will be a lot easier than changing the cam...
Individual valve control. DSI merges with iVTEC. (Score: 1, Normal)
