Standart head height is VANOS is fully variable and operates independently on both intake and exhaust sides. Published date Thursday, 01 June The engine was manufactured on Munich Plant Munich, Germany from to The aluminum cylinder head uses chain-driven double overhead camshafts DOHC and four valves per cylinder 24 valves in total. The S54 is the high performance equivalent to the M The S54 is technically an evolution of the iron-block S50B It shares few major components with the S50 and differences include. Six high-performance pencil ignition coils with integrated ignition drivers are used for the ignition. When the piston is forged skirt pistons with connecting rods for high-strength steel connecting rods.

There was still a slight increase in displacement against the S50B32 from 3. This was a further increase in capacity and thus increase performance in the way. The extra capacity is achieved using an increased stroke of There was also a slightly more powerful version of the M54B30 that could be ordered as part of the M Performance package in Canada or the Performance package in the USA.

The partially significant increases in output 28 kW in the case of the 3-liter engine were, however, achieved for the most part by reducing the flow resistance on the inlet and outlet side of the engine. The M52B20 was replaced in by its successor from Mseries - 2. The engine firstly has the variable timing system VANOS on intake camshaft only, and simple intake manifold made from plastic.Īfter the engine got the new name - M52TUB There are cast iron sleeves inside new aluminum cylinder block.Ĭonnecting rods, pistons, cooling system, everything was redeveloped for this engine.
