Rest In Peace, old friend, your work is finished.......

If you want on or off the DIESEL "KNOCK" LIST just FReepmail me........

This is a fairly HIGH VOLUME ping list on some days......

Knock!......

this nonsense will require valve springs so weak that they won't seal the cylinders; or electromagnetism innovations that are currently off-the-scale to overcome valve-spring tension requirments.

You will see engines with this system on the road in the same dream as you see cars with hydrogen fuel.

Notice they claimed "up to 20%". 1 or 2% improvement is all they are likely to see (maybe). I have a dyno and I see these claims all the time. What is really interesting is to listen to the salesman's claims before and after I tell him I have a dyno. I have seen claims go from 50% improvement down to I probably wouldn't be interested, as they quickly try to get out of the conversation.

I recall first hearing about research into eliminating camshafts by electromechanical means back in the 1990's. Good to hear somebody is keeping up the research. Weren't all vehicles supposed to have 42-volt electrical systems with flywheel starter motor/generators by now?

I would think valve timing has more to do with economy and power than reducing friction in the train. I can't believe it takes more than a couple of horses,(5-10?) to turn a cam and lift valves. 20% of a 200hp engine would be 40hp.
