DI Diesel Engines M57/M67 - Common Rail

Introduction

BMW is successively developing a new family of diesel engines
with direct injection (DI) that will include 4-cylinder,
6-cylinder and 8-cylinder engines.
Following the successful introduction of the M47D20
4-cylinder engine, a new 6-cylinder engine will soon be phased
into series production.
This engine features all the design characteristics of the second
generation of direct injection diesel engines and represents the
currently most advanced diesel technology available in passen
vehicles.
Thanks to its outstanding performance and high comfort properties
in conjunction with excellent exhaust quality and integral
economy, this engine enjoys a leading position in the
competitive environment.

Initially, the new M57 engine will be installed in the form of a top-
of-the-range diesel engine in the 5 and 7 Series. The M67 will
enhance the top end of the diesel engine range in the 7 Series.
Parallel to this, the well-proven indirect injection engines (IDI)
still remain in the product range.
