M57/M67 Common Rail Concept

without comments

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, passenger 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.

The superiority of these engines is the result of non-compromising basic engine design (modular system) in conjunction with progressive technical concepts.
