1.N54B30
In order to meet more stringent emission regulations, but also to meet consumer demand driving pleasure, BMW introduced a twin-turbo N54 engine in 2007, it began turbo road, but it also makes a lot of love naturally aspirated BMW fans feel dejected, but BMW still use its own strength proved to the world’s powerful N54.
of this code for N54B30 3.0L twin-turbo engine with a plurality of different adjustment to match the model BMW’s various levels. Wherein the maximum power reached version 335 horsepower (250kW) / 5900rpm, 450Nmiddot; m / 1500-4500rpm.
In fact, this is the N54 engine from 2001 that sets the design extremely well naturally aspirated inline six-cylinder engine N52, it almost can use all the technology to BMW engines other than turbo-charged , reached the same level of the best dynamic performance, N54 and N52 engine inherited outstanding, an increase of two small-diameter turbochargers on the basis of proven design, while the introduction of advanced direct injection technology, its power of N52 has been greatly improved in comparison.
BMW engineers in the engine N54 in a number of experimental work, the result is significantly improved exchange or power, and two small diameter of the turbine can be started at a lower speed, so that to achieve N54 the rapidly approaching naturally aspirated engine throttle response. However, due to the double structure so that the intake and exhaust system of the turbine engine N54 is relatively complex, but also canceled BMW advanced Valvetronic electronic valve technology.
BMW N54B30 technical parameters the displacement of 2996ml arranged in the form of a cylinder line six-cylinder [ 123] bore 84mm stroke 89.6mm or power 112 horsepower (83.3kW) / L maximum speed 7000 rpm maximum power 335 horsepower (250Kw) / 5900rpm maximum torque 450Nbull; m / 1500-4500rpm [ 123] specific technology bis turbo
relatively sophisticated tuning the engine N52, the N54 though parameters looks very nice, but in the design on is not mature enough and perfect. However, N54 engine can be said that BMW turbo technology in a bold attempt and innovation.
