The BMW M57 is a straight-6 diesel engine produced from 1998. It is produced in the upper Austrian engine plant in Steyr.

Description

The M57 is a water-cooled and turbocharged inline six cylinder diesel engine with common-rail-injection. It was revised twice during its production time. It is based on its predecessor M51. The block and the crankcase of the first M57 engines and the TÜ (Technische Überarbeitung = revision) engines are made of cast iron, TÜ2 engines are made of aluminium instead.[1] The combustion chamber was also changed in the TÜ2.[1] The injection pressure is 1350 bar[2] in the 2.5l engine, all other engines use a pressure of 1600 bar instead.[2] For fuel injection, magnetic injectors are used, except from the TÜ2 OL and TOP engines, which make use of piezo injectors.[2] The common-rail-system is made by Bosch and also controlled by a Bosch DDE 5 ECU.[3] The M57 is equipped with one variable geometry turbocharger and an intercooler, except from the M57D30TÜTOP, which has a BorgWarner KP39 high-pressure and a K26 low-pressure turbocharger.[4] The compression ratio reaches from 16,5:1 to 18:1, M57 engines with higher power output and more than one turbocharger have a lower compression ratio.[5] Every cylinder has two inlet and two outlet valves as well as two chain-driven overhead camshafts.[6]
