The Mercedes-Benz OM628 engine is a turbocharged diesel V8 engine produced by Mercedes-Benz, from 1999 to 2005.
Design
The OM628 was created in response to competing V8 diesel engines produced by Audi and BMW.[1] It first appeared in the W220 S400 CDI and was subsequently the first V8 diesel engine in a Mercedes passenger vehicle. The OM628 engine features dual overhead camshafts, 4 valves per cylinder, exhaust gas recirculation, a Garrett GT1749V turbocharger, and Euro 4 emissions compliance.[2] The engine block and cylinder heads are made from an aluminium alloy, via the sand-casting process.
