So for the L94UB, L113CRL, N113CRB, it would have been like:
L94UB - L: Longitudally mounted engine, 60 degrees angle, 9: 9L
engine, 4: 4th Gen, UB: Urban citybus
L113CRL - L: Longitudally mounted engine, 60 degrees angle, 11:
11L engine, 3: 3rd Gen, C: 2-axle single decker, R: RHD bus, L: Low
entry
N113CRB - N: Transverse engine, 11: 11L engine, 3: 3rd Gen, C:
2-axle single deck, R: RHD bus, B:Regular non-low-floor bus
Did I get it right?
Accurately speaking the engine is mounted, on a tilted angle 30
degrees NW to SE (as picture illustrates below). '30 degrees' is
used by Scania to illustrate the engine placement as well, as it is
'raised' 30 degrees from a flat position. Nonetheless 90 - 30 = 60
which is also a correct representation. In that case, 60 degrees
from upright.
The main reason for this is to reduce compartment intrusion for
lower entry (one-step or less) buses, at that time in Europe. Do
note that this engine placement cannot be done to any existing
upright mount engine, lots has to be done especially the engine oil
pan, which enables the engine to suck up engine oil at a 90 degrees
angle. Hence there is a 'out-of-shape' oil pan if you get to see
the engine, you will understand how it looks like.
