Mercedes-Benz OM604, OM605 and OM606 engines


The Mercedes-Benz OM604, OM605 and OM606 were part of a family of diesel engines with inline four, five and six-cylinders, respectively. The OM604, OM605 and OM606 engines all had cast iron blocks, alloy cylinder heads, indirect injection, double overhead camshafts, four valves per cylinder (a first for passenger vehicles with diesel engines), compression ratios of 22.0:1 and exhaust gas recirculation.

While the OM604 was not turbocharged, the OM605 and OM606 engines were available in naturally aspirated and turbocharged forms. While the OM605.96x had a Garrett GT25C turbocharger, the OM606.96x engine had a 3k K14 turbocharger.

The OM604, OM605 and OM606 engines were replaced by the OM611, OM612, OM613 engines.
