The latest generation of broadly re construct 6-cylinder diesel engines is making its way onto various BMW models this summer. The latest B57 inline diesel engine, with a displacement of 3.0 liters, boasts all aluminum cylinder block construction and a further flourished BMW Twin Power Turbo automation with optimized turbo charging process.
The powerful 6-cylinder power plants are also amplified with mild hybrid by means of the 48-volt connected starter generator. Moreover, the host of BMW powerful Dynamics solutions applied for the latest diesel engines involve modern generation of the common rail direct injection with piezo injectors.
They are efficient of performing up to 10 injections per engine cycle, whereas the injection stress achieved reaches a maximum of 2,700 bar, remarkably increasing both the performance and running effectively of the diesel power engines.
The Modern B57 engine family specs state of the art exhaust gas after treatment, employing a diesel oxidation catalytic converter and SCR coating for the diesel particulate filter (DPF).
An extra Ad Blue dosage unit is fixed at the engine outlet of the Selective Catalytic Reducer (SCR) system, which helps cut the NOx emissions even more. Thus, the latest diesel power plant generation is now compeletly compliant with the strict EURO 6d standard.
The two latest 6-cylinder engines accessible for the BMW 7 Series and X models come in two power level: 210 kW / 286 PS (282 hp) and 250 kW / 340 PS (335 hp).
The 286 PS diesel units now premiere on the latest 730d, 730d xDrive, 730Ld and 730Ld xDrive versions. Boasting a peak output increase of 21 hp over the outgoing engine, the latest 6-cylinder diesel unit specs multi-level turbo charging and variable turbine geometry for the low-pressure level.
Thanks to the latest technical measures, the highest torque of the 730d/730Ld is enhanced to 650 Nm from 620 Nm on the outgoing power plant. The outstanding torque level is available early, from 1,500 rpm 2,500 rpm, which make sure a energetic power boost and increased sprint capacity.
The 0-100 km/h speed is also enhancing by 0.2 seconds: 5.9 seconds for the rear-wheel drive 730d/730Ld and 5.6 seconds for the modern 730d xDrive/730Ld xDrive.
This variant of the modern 6-cylinder engine will also power the following makes: X3 xDrive30d, X4 xDrive30d, X5 xDrive30d and X6 xDrive30d.
The 340 PS diesel units are now present on the new 740d/740Ld xDrive versions. More models include on which the engine is fixed comprise the bmw X3 M40d, the X4 M40d and the X7 xDrive40d.
The biggest torque expand to 700 Nm, generate between 1,750 rpm and 2,250 rpm, empower fast acceleration times of just 5.0 seconds in the modern BMW 740d xDrive, for example (0.2 second enhancement).
