Further Development of the Six-Cylinder Engines

When Mercedes-Benz enhanced its mid-series in autumn of 1992, the previously installed six-cylinder engine with four-valve technology and 3.0 litres total displacement [1] was replaced by the four-valve engine with 3.2 litres total displacement familiar from the new S-class [2]. For this application, the engine was subjected to still further development in terms of combustion mixture preparation and engine management, and a variant with a total displacement of 2.8 litres was added. This engine replaces the engines of 2.6 total displacement [3]. This further development, and the new engine, are described below.
