Since the Miller cycle engine is a derivative of the Atkinson cycle engine turbocharging is out of the question. Since the fuel "burn" cycle is so...
A HIGH compression low HP DFI Atkinson cycle engine, 18:1/40HP, driving the front wheels, and an INSTANT start miller cycle DFI engine, 10:1...
The advantages of DI come into play only when the compression heating due to the high(er) compression would otherwise threaten detonation.
Somewhere I have read that SFI is only used during engine idle. That would make sense to me as a way to combat the problem of EGR residue deposits...

The current Toyota HSD Atkinson cycle engine simulation, as in teh Prius, RXh and HH, uses a base/native CR of 13:1 but an effective CR of ~10:1....
"..the way it will be used.." I took factory delivery of a C4 911/996 in '01 and was told that I would not always be able to buy premium in our...
So, what's the difference between Toyota's current Atkinson cycle "simulation", pushing ~30% of the cylinder charge back out into the intake...
For 2011 both the GS350 and the GS450h have a CR of 11.8:1, reasonable with DFI. With the Atkinson cycle engine using the delayed into valve...
"...3.5L DI did get a through reworking..." No, an Atkinson engine using DI should have a base/native compression ratio on the order of at least...
Why...???
"...do away with SUV hybrids..." No, just don't overpower them to the point of finding it an asset to quote 0-60 times. Do away with the...
Just another GAS HOG cashing in on the hybrid theme. This will likely go the same way as the LS600h. Hybrids should be about FE, not an...

If I remember(***) correctly the Lexus RX450h shop/repair manual indicates the intake valve timing change is as much as 120 degrees. That should...
For intance, the Skyactiv system could run a CR of ~17:1 in Otto mode, low cylinder fills, and switch back to 14:1 for WOT.
