This report covers a detailed design benchmarking study of the Mercedes IL6 3.2L diesel engine and includes a photographic record of all the main components, plus individual masses and dimensions. Ricardo comments on specific design features are also included.
The Mercedes Benz OM613 engine was designed as part of a family inline diesel engines, available in 4,5 and 6 cylinder variants. These engines were introduced in mid-1999 for installation in the updated E-class. The engine family has variants ranging from 2.2L to 3.2L, each engine featuring variable nozzle turbine turbochargers and common rail fuel injection. All engines feature 4 valves per cylinder, operated by double overhead camshafts.
The engine block is of cast iron construction and the head is of aluminium construction. The 6 cylinder engine has a specific output of 45kW/litre, with the highly rated 4 cylinder engine variant achieving 48.9kW/litre. The maximum power is 145 kW (~197hp) at 4200 rpm
