In order to meet more stringent emission regulations, but also to meet consumer demands for driving pleasure, BMW introduced a twin-turbo engine in 2007 N54, began its turbocharged road, but this also make 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 is almost use the BMW engine can provide All except the turbocharged technology, to achieve 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 has been greatly improved compared to the N52.
BMW engineers in the engine N54 in a number of experimental work, the result is significantly improved exchange or power, and two small diameter turbine can be lower starting speed, so to achieve a fast approaching N54 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 specific technology bis turbo
relatively sophisticated tuning engine N52, N54 while watching parameters up very nice, but not enough to mature and improve on the design. However, N54 engine can be said that BMW turbo technology in a bold attempt and innovation.
