    Hi gents,

    I'm looking for the compression ratios of the following engines:
    • Detroit Diesel Series 60 11.1L pre-EGR
    • Detroit Diesel Series 60 12.7L pre-EGR
    • CAT C10
    • CAT C12 pre-ACERT
    • Cummins ISX12 & X12 SCR
    I'm also looking for the max governed RPM of the following engines:
    • Detroit Diesel DD13 SCR
    • Cummins ISX12 & X12 SCR
    Any information will be appreciated.

    These are the ones I could not find by Google. I did find Series 60 EGR.

    15:1 or 16.5:1
    15:1 or 16.5:1
    16:1
    16:1
    ISX15 is 18.9:1, so probably similar

    2,600RPM

    2,500 RPM

    This is the most accurate info I can find, cummins doesn't like listing those kinds of specifications apparently.

    Thanks!

    How do I know if a Series 60 has a 15.0:1 or a 16.5:1 compression ratio?

    Can the DD13 safely get to 2600 RPM or is it governed to something less? The older Series 60s were governed to 2100 RPM.

    Also, a CAT spec sheet says the C10 is governed to 1800 RPM but someone else says they can do 2100 RPM. Is it safe to do 2100 RPM in a C10?
