The BMW B47 is a four-cylinder common rail diesel engine produced by BMW. It debuted in 2014 as the successor to the previous N47 engine. While the B47D models are used in rear-wheel drive cars, the B47C variants are used with front-wheel drive.
Design
The B47 engine is part of the modular family of engines, along with the B38, B48, B57 and B58. The B47 complies with the Euro 6 emissions standard, and features a dual overhead camshaft with 4 valves per cylinder and a single turbocharger; while 165 kW (221 hp) and 170 kW (228 hp) engines feature twin-turbochargers. In November 2017, a technical update (codenamed B47TÜ1) added AdBlue injection and higher injection pressures. Twin turbo for both 318d and 320d.
