1995 E36: which 2L engine type M50TU ot M52? |
|
|
Would a UK-spec E36 320i Touring from 1995 be fitted with an M50TU or M52
engine? Can I tell from just the engine number (which I have)?
Thanks in advance.

The M52 is an OBD II compliant motor, used from 1996 and later in the USA.
I'm just guessing here, but I suspect you have the M50 that was used up to
(and including) 1995.

Thanks Jeff, but I've just answered my own question. I keyed the VIN number
into the TIS software. Turns out it is a 1996 M52 unit after all (which is
not what I wanted to seel). I was hoping the vehicle had an M50TU.
Guess I'd now better do a compression test prior to handing over the cash.

Why would you prefer the M52 over the M50?
The M52 has an advanced diagnostic system. The 2.5L version also makes more
torque faster that peaks higher. I am not sure what the specs are of the
european version are, but if I could pick one over the other, I'd take the
M52 in a heartbeat.

The M52 is a later designed engine than the M50TU, but both have a single
VANOS unit if that was influencing your preference.
But, being a later design would suggest the M52 is the better engine.

Mike.
What was influencing my choice was the fact that the M52 (in Europe) had the |
aluminium block (nicasil!!) unlike the iron block of the US M52.

Its always nice to have the OBDI though, purely for the fact that a
check engine light wont negate your emissions test. If you have a 1996
or later, it must be OBDII compliant and any error will cause you to
fail emissions, whether you are out of compliance or not. with an OBDI
they actaully have to hook up the monitors to your exhaust and get a
real reading. |

wish that logic would cross the pond, post 96 they just plug in the
computer, thats it and thats all, I figure you could be on fire and
blowing black smoke fifty feet into the air and you would pass as long
as the computer gave the right reading... |

On the bright side, I bet it's far easier to screw with the wires to
the Lambda sensor (insert a resistor maybe) and improve the emissions
(as far as the tester with the laptop is concerned) than it is to sort
out the fog coming out the back into the face of the man with the
probe!

Actually - it's difficult to do. A O2 sensor puts out a voltage - which
varies according to the mixture it sees. The typical crossover is 250ms
(1/4 second) - and the emissions monitoring systems will trigger a fault
if the response is too slow (more than 500ms or so) or if the voltages
fall out of range.
While one could (and people have) make a circuit to emulate this
behavior - on a modern car - it is not a good thing to do, since the
emulation doesn't give the FI system feedback, so the actual mixture
being burned is not going to be right - it will be rich/right/lean - and
rich or lean can damage the engine.
It might be a tad easier to install a new O2 sensor. |
