Introduction
Engine N45 and N46 (not N45TU2 and N46TU2):
>
E46
The new generation of 4-cylinder spark-ignition engines (NG4) are continued and developed further.
The 4-cylinder spark-ignition engines N40 and N42 have been redesigned.
The modified N40 engine is now called N45.
The modified N42 engine is now called N46.
As with its predecessor, there are 2 engine-capacity versions of the N46:
N46B18 (1.8 l) and N46B20 (2.0 l). The available power output remains unchanged at (85 and 105 kW).
As on the predecessor version N42, the new N46 is available as a version for various southern and eastern
European markets.
The N45B16 (1.6 l) has the same rated output as the N46B18. The N45B16 has no Valvetronic system and no
differential air intake control (DISA).

E87, E90, E91
On the E87, the N45 is the basic engine for all countries (EURO 4, without Valvetronic and DISA). The N46 is
available in a lower power rating (N46B20UL) and in a higher power rating (N46B20OL).
There is also no differential air intake control (DISA) on the N46B20UL.
For both N46 power ratings, there is no air mass meter signal (for vehicles with catalytic converter). With effect
of 06/2006, the air mass meter has been reintroduced for countries where the fuel quality is inadequate.
