Guide to engine codes

Just been reading a guide, so I thought I'd post the details up on here incase anyone's interested

The first digit of the code relates to the emissions regs the engine meets.

Z = euro 4
Y = euro 3
X = euro 2
C = euro 1

Cars made before the emissions regulations have no letter at the start of the code.

The next 2 digits are the capacity.

For example, the 20 in C20 XE means 2 litre.

The next letter is the compression ratio.

G = 8 to 8.5:1
L = 8.5 to 9:1
N = 9 to 9.5:1
S = 9.5 to 10:1
X = 10 to 11.5:1
Y = 11.5+:1

The next digit relates to the fuelling.

D = diesel
E = multi-point injection
Z = single-point injection
V = carburettor

Some engines have an extra code at the end, if they are different from normal

For example:

H = high output
R = increase output
T = turbo
V = volume model
B = IBC (Inverted Brayton Cycle, in laymens terms, the recurculation of gasses)
C = Corporation ignition system
F = Vehicles for Authorities
H = High output / Supercharging
I = Irmischer
J = Throttled Output
K = Komplex
L = Low output / Supercharging
P = Power Adapted
R = Increased Output
T = Turbo
U = Uruguay
V = Volume model
W = Venezuela
2 = Family II engine

Nice to see someone trying to help everyone out though.

Yep I'd never seen it before tbf...

Ofcourse

Heres an extra added bit which shows what the last digit means:

The last digit on the end of the code will denote if an engine differs from a sister engine, is produced in another counrty, or any factory exra bits! As follows....
B = IBC (Inverted Brayton Cycle, in laymens terms, the recurculation of gasses)
C = Corporation ignition system
F = Vehicles for Authorities
H = High output / Supercharging
I = Irmischer
J = Throttled Output
K = Komplex
L = Low output / Supercharging
P = Power Adapted
R = Increased Output
T = Turbo
U = Uruguay
V = Volume model
W = Venezuela
2 = Family II engine

CORSA VXR Z16LER = Euro 4, 1598cc, compression ratio 8.5-9.1, multi point injection, increased output(189Bhp standard map).
CORSA SRi Z16LEL = Euro 4, 1598cc, compression ratio 8.5 -9.1, multi point injection, Low output(147bhp standard map).

they really are quite similar

Hi,

Is there an update as to the meaning of the A, as in A16LER on my VXR Nurburgring?

Cheers

Going by the lists above:
A = Euro 5 emissions compliant
16 = 1.6L
E = Multi point injection (injector per cylinder)
R = Increased power output.

Aye, thanks. That was the assumption I made, but wanted to have confirmation from someone who knows.
