Editing Stratified charge engine (section)

===Mercedes-Benz===

[[Mercedes-Benz]] has been employing stratified charge engines with its Blue DIRECT system.

<blockquote>
With the stratified-charge application, the 3.0L V-6 will continue to employ direct fuel injection, but the injectors have been redesigned to spray under higher pressure later in the intake stroke, just before compression, and the fuel is shaped to arrive in certain areas within the cylinder to optimize combustion.
This strategy makes for an air-fuel mix within the chamber that is much leaner than with a conventional homogeneous-charge system that fills the chamber more uniformly before combustion.
