Available from 2014, the BMW B47 was a four-cylinder turbo-diesel engine. The B47 was a part of BMW’s modular family of engines which included the three-cylinder B37 diesel engine, the three-cylinder B38 petrol and the four-cylinder B48 petrol engines. For three- and four-cylinder engines of the same fuel type, around 60 per cent of components were shared; for engines of different fuel types, around 40 per cent of components were shared. All four engines were manufactured on a single assembly line at BMW’s Steyr plant in Austria and production was estimated at 5500 engines per day.
The standard B47 engine had an aluminium block and cylinder head, a single-scroll turbocharger with variable turbine geometry (VTG or VGT), common-rail direct injection with solenoid injectors (providing maximum injection pressure of 2000 bar), double overhead camshafts (chain-driven), four valves per cylinder and a compression ratio of 16.5:1.
The higher-output B47C20T0 engine standard, however, had multi-stage high- and low-pressure turbochargers and solenoid injectors which provided maximum pressure of 2500 bar.
The B47 replaced BMW’s N47 turbo-diesel engine.
