OK thanks for all the goodies on the 3.5. I do seem to remember that most of the injection events were at or after TDC, thus killing the knock causing pre-detonation normally caused by high compression ratio. That would also add more torque to the engines power band.
Ford's had a few years and this engine has proven very reliable, from what I have read. Good for them. They've had a history of poor engines (diesel) for a long time, the current 6.7L not included, and it's good to see an American car company kick but on power and fuel efficiency over the imports. Now, if the EB engines will last 200-300,000 miles, then it's a no brainer. I am seeing quite a number of them for sale after exceeding 100,000 though, so that is a concern.
Do the 4 cyl Ecoboosts work the same way?
One poster asked about high fuel rail pressures, and yes, they do run high enough to overpower cylinder pressure (diesel, I do not know about the EB, but I assume it does as well). That's why diesel fuel rail pressures will run as high as 26K. The high pressure also atomizes fuel better, which means more efficiency.
I assume the additional fuel events, are burned from the existing cylinder heat, and not from an additional spark event?
