3-Turbo Diesel Engines BMW, Torque 2 occasions VNT Fortuner

Current diesel engine technology is not inferior to gasoline engines. The proof was owned BMW. At the Geneva Motor Show 2012 ago, showing the sophistication of the latest diesel engine M550d sedan and SUV series X5 M50d and X6 M50d.

Once configured V petrol engine equipped with twin turbo diesel this time that will be championed BMW to bring the big names of the famous M type fast.

Unmitigated, 3 pieces mounted on the engine turbo diesel inline 6-cylinder coded N57D30, the kind that many installed in BMW variants, such as 530d. Everything greatness is combined with aluminum crankcase, common-rail direct injection with piezo injectors that have very high pressure and precision. Just imagine, an injector should be able to blow away the fuel pressure 2200 bar!

Third turbo obviously been equipped with a system of variable turbine geometry (VTG). Combinations derived from 2 fruit small turbo and a large turbo. The result is a maximum power of 381 hp and torque of the range nearly two times as much, 740 Nm! Not only get a great power. Guaranteed this latest generation diesel got wider powerband range. Roughly, it can be more than 2 times the torque of the Toyota Fortuner VNT.

The way it works, the engine speed is very low, ranging from 500 rpm, a small turbo would make the acceleration feel more spontaneous. VTG system will continue to generate pressure up at more than 1,000 rpm.

Furthermore, from 1,500 rpm to 3,000 rpm, a large turbo will continue to pressure from the turbo first, to produce torque without having to undergo extra-lag turbo engine so the main problem.

Next, the third turbo smaller turbo will keep the pressure ranging from 3,000 rpm to limit the red line at 5,500 rpm.

As a result, if mounted on M550d xDrive sedan series, this machine can record acceleration of 4.7 seconds to reach speeds of 100 km / h. Remember, thanks to the system that makes VTG wider powerband, all this effort had begun when the rpm needle is in the down position.

Until now, it’s new diesel engine with inline configurations are qualified to use this technology. However, imagine when the 3-turbo setup installed on a machine with V.
