BMW N52B30

The BMW N52 is a straight-6 DOHC piston engine which was produced from 2004-2015. It debuted on the E90 330i and E63 630i. In European markets, it began to be phased out following the release of the N53 in 2007. However, in markets such as North America, Australia or Malaysia,[1] the N53 was deemed unsuitable due to the high levels of sulfur in the fuel. Therefore, the N52 remained in production until its replacement by the N20 turbocharged 4-cylinder engine[2] in 2015. Compared with its M54 predecessor, the N52 features variable valve lift (called Valvetronic by BMW),[3] a lighter block due to the use of a magnesium alloy[4] and an electric water pump and a variable oil pump.[5] Like the M54, the N52 uses an electronic throttle control, variable valve timing to both camshafts (called dual VANOS by BMW) and a dual length intake manifold (called "DISA" by BMW).[WIKI]
