Engine designations
1. Basic markings:
320
,
420
,
620
and
634
. The first digit indicates the number of cylinders and the two last digits the stroke
(---20=120 mm, ---34=134 mm).
2. Letters after the basic markings:
--- D =diesel engine
--- S =turbocharger (Schwitzer)
--- W =
by--pass turbocharger, Delta turbo (Schwitzer S1BG or S2BG)
---
B
=Bosch P in---line pump
--- R =distributor pump (Stanadyne)
--- I =intercooler
--- E =low emission engines (E---engines)
---
C
=emission tested engines (certificated).
Note! R24, E77 and EPA---homologations has been made for E---engines.
