Actually for being diesels their compression ratio is quite low! 15.3:1! I've seen diesels go as high as 22.5:1 and as low as 14.5:1, though according to a quick search, the actual range for diesels is 14:1 to 25:1. So yeah, GEVO-12s are on the lower end of the spectrum. EMD 710 is in the same range, as is the EMD 1010J/265H engine family.
These things sound so much better going past you in real life we have railroad tracks in my neighborhood nothing but Norfolk southern, bnsf, and Union Pacific blast throughout the neighborhood
I live just above the BNSF mainline as it leaves the Surrey/Vancouver BC yard about a mile away from my us on its way to Seattle. Nothing like the sound of 3 Units under load getting a train up to speed!
The uaw killed emd and detriot diesel. G E was paying half the hourly wages. CEO Wagner couldn`t say no to anyone. Emd turned out some sorry engines. Wagner GAVE DD to penske. But look at the U S now 3 of the class 8 trucks manufactors are foreign owned
