All the major OEM are testing these.

:lol: at 10% improvement in fuel economy
Changes to the ignition source isn't going to give you any additional MPG in a vehicle in the real world. Weight, aerodynamics, heat losses are the elephants when it comes to fuel economy, the spark/ignition source is a flea.
If these actually worked they would have been already in use in motorsports by now. Instead most vehicles still use 50yr old spark plug designs. There's a reason for that. :idea:

Truth.
Ignition source is virtually irrelevant in determining how efficiently fuel is burnt.

Yeah the reason is COST, you see if the big 3 is willing to get rid of almost every grease fitting on the front end steering/suspension of the car just to save 0.05 Cents per each for I believe in 11 locations on the front end equaling to 0.55 Cents per car X however many cars they make a year?If these actually worked they would have been already in use in motorsports by now.

yea, it's all about burning all the fuel you can. our current spark ignition engines are absolutely NOT burning 100% of the fuel in the combustion chamber, we still have room to improve in that territory. if they were burning nearly everything that went into the combustion chamber, then major manufacturers wouldn't be dumping money into HCCI research, and diesel engines wouldn't hold the efficiency edge.Sorry man, not entirely true.
Diesel vs gas is a great example. Not exactly a direct comparison, but still holds some validity. A more uniform combustion typically yields better efficiency.
Anther example is the 6.2L Ford V8. The main reason they use twin spark plugs is to increase combustion efficiency by enabling a more uniform burn.
I do agree that 10% is probably a way best case lab scenario, or this would have been invented years ago.

and we wouldnt have EGR's
