DI Diesel Engines M57/M67 - Common Rail Sec. 1 P.3
Course contents/Background material
Concepts
The concept features of the new engines correspond to those of
second generation DI diesel engines.
The advantages in fuel consumption offered by the first series-
produced DI diesel engines were offset by a series of
disadvantages regarding acoustic comfort, performance, emission,
pas
senger compartment heating and costs compared to modern
IDI
diesel engines.
In contrast to this, with second generation DI diesel engines it
has been possible to improve all customer-relevant features,
with
the exception of costs, by incorporating new or further
developed
technical concepts.
In-line design Direct injection 4-valve technology
2nd generation

Fig. 2: Technical concepts
The superiority of these engines is the result of non-compromis-
ing basic engine design (modular system) in conjunction with
progressive technical concepts.
