I can only help with Cummins designations for their engines.
Mechanical engines were always designated by block size..B5.9, C8.3 etc. The numeric designation was displacement in liters.
Electronic controlled engines with 4 valves per cylinder (vs. 2 valves in the mechanical engines) were the successors to the mechanical engines. ISB, ISC, etc.
The first ISB's were ISB5.9...now the displacement is 6.7 liters hence the new coaches with the ISB6.7 engines.
Many new buyers of DP's only pay attention to H.P. ratings...but it is displacement that determines torque and is equally if not more important than H.P.
One other note, Cummins manufactures these engines with different H.P. ratings for different applications.
Hopefully others with chime in, but currently only Cummins and Detroit Diesel are supplying engines for the US DP motorhome market.
