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 1,350 bar (19,600 psi)[2] in the non TÜ engine, all other engines use a pressure of 1,600 bar (23,000 psi) 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 4 ECU for non TÜ and DDE 5 ECU for TÜ.[3] The M57 is equipped with one Garrett GT2556V turbocharger and an intercooler, the M57TÜ uses a Garrett GT2260V turbocharger and intercooler and the M57D30TÜTOP uses a BorgWarner KP39 high-pressure and a K26 low-pressure turbocharger.[4] The compression ratio reaches from 16.5:1 to 18.0:1, M57 engines with higher power output and more than one turbocharger have a lower compression ratio.[5] Every cylinder has two inlet and two exhaust valves as well as two chain-driven overhead camshafts. The redline is 4750 rpm.
