Just exactly what do they all mean? It's not all that important, but for some reason it's driving me nuts.

I tried a feeble search, but didn't find anything specific to the question.

Hi Corkey,
It is just Cummins way of labeling their different engines. As best I remember, the IS stands for integrated circuit. The last letter is the engine family. B is the small and X is the large. The letters inbetween B and X indicate where the engine family falls in the size wise line up.

engine types
If you are asking what does the 'B' stand for, sorry. But you did get my curiousity going.

Found this:
ISB Interact System B: Cummins designation for the 24 Valve "B" series diesel introduced to the 1998 Ram

The "IS-" series of engines are electronically controlled as opposed to the older mechanically controlled engines.

----------------------------------------------
Cummins has a very long history of naming its various engines by letter designation; sort of like the old Fords i.e. model A, B etc. The most long lived was the H (5/1/8"bore)and then NH (New H)(5 1/2"bore)). So, with the release of the new IS (Interact System which allows for interaction of various non-engine components from ECM)version they simply picked up the letter from the series i.e. B became ISB, C became ISC. The latter larger versions like ISM, ISX are new but continue the letter tradition. To confuse things, Cummins has at time used names like VIM/VINE to designate V type engine 6 cylinders (VIM) and 8 cylinders (VINE) and then later went to VT-903 when they went to a large V8. Then , in 1970's they released the K in line series and denoted them as KT-450, etc. In other words, there is no real strict code parse to their numbering convention - one has to just become familiar with the engines but one can say that a single letter means mechanical and IS means electronic controls.

Ecker, thanks for the rundown. Once I get a grip on all of this, I think I will be able to drive defensively in the fog.

LewF, thanks for the link. It provides a good history lesson, probably take me a month to soak it all up, I'm slow but deliberate.

Not knowing was, as I said, "driving me nuts", now I know and the other half says I'm still nuts.

Thanks all for responding, ... informative.

While we are on the subject I was wondering what the AD designation meant as in the ISB 300 AD which is one of the engines listed for RV application.

I will have to check to be sure but I think it means air compressor delete. You can not select the air compressor option on this engine. This version is designed for low cost entry level diesel motor home like Monaco LaPalma which has hydraulic braking. In addition, it comes with a three year warranty not five to further lower cost.

The "I" and the "s" simply state the type of the engine layout. "Inline Six" .Cummins started using this prefix when they started selling their product to the general public in dodge pickups. Before that, they were just designated by series , a,b,c,....and so on.You will never a veteren trucker use the letters "I" "S" when talking about what engine he's got under the hood,He (or she) will say,"Iv'e got a cummins M series"
