DAS MOTOR HAUS NEW OM642 3.0L V6 DIESEL ENGINE ASSEMBLY MERCEDES DODGE FREIGHTLINER 2006-2022

The DAS MOTOR HAUS new Mercedes-Benz OM642 Engine is a 72-degree V6, dual overhead camshaft (DOHC), 24-valve turbocharged diesel engine. This 3.0-liter common rail diesel powerplant succeeded the inline-five and inline-six diesel engines in Mercedes-Benz's passenger car and light truck lineup, entering production in 2005. The OM642 is constructed with a compacted graphite iron (CGI) cylinder block and aluminum alloy cylinder heads. 

The engine employs a third-generation common rail direct injection system with piezoelectric injectors, variable geometry turbochargers (single or twin, depending on variant), and a sophisticated emissions control suite. The 72-degree V-angle allows for optimized packaging and primary balance. The OM642 delivers high specific output, robust low-end torque, and refined operation, though it presents specific maintenance challenges related to its complex emission systems. It is engineered for longitudinal and transverse mounting in a vast array of rear-wheel-drive, all-wheel-drive, and front-wheel-drive vehicles.
