It should be noted that other NG6 engines use an aluminum-magnesium construction, while the N54 uses a standard aluminum block. BMW dealers' first response is to perform HVA bleeding procedure, however this procedure seems not to resolve the matter. The three-stage resonance suction system achieves higher torque at low speeds and higher power at high speeds. Engine specifications << Go back to engine overview. Alusil, when etched, will expose a very hard silicon precipitate. Just doing a quick search brings up several quality brands that meet these specifications and can be purchased online*. The lightweight construction camshafts were manufactured by hydroforming . Engine. At very high oil temperatures, heat is transferred to the engine cooling system via the heat exchanger. Pre-Owned. It is BMW's first mass-produced turbocharged petrol engine and BMW's first turbocharged petrol engine since the limited-production BMW M106 was discontinued in 1986. There were 2 versions, the N52B25, and N52B30. BMW Diesel Videos. The diameter of intake valves is 32 mm; exhaust valve diameter is 29 mm. The case is about 24% lighter than a comparable aluminum component or 57% gray cast iron. The direct inlet control on the cylinder reduces the flow losses. A throttle valve is still available, but is used only in very few operating conditions supportive and has mainly the function of an emergency operation system. The N52 engine intake bolts right up to the N51 engine. dessen Nachfolger dem BMW M52-Motor entwickelt wurde. Thus, magnesium in its pure form or as a conventional alloy is not suited for permanently conveying high loads and forces of the kind typically encountered in central components of the engine. Der N52 war komplett neu entwickelt, wobei im Vergleich zum M54 das Gewicht um 10 kg verringert, der Verbrauch um 12 % gesenkt und die Leistung um 20 kW gesteigert werden konnte. The low weight was achieved, among other things using a novel magnesium-aluminum composite cast crankcase . Like the M54, the N52 uses an electronic throttle control, variable valve timing to both camshafts (called dual VANOS by BMW) and a infinitely variable length intake manifold (called "DISA" by BMW). Der BMW N52 war ein Reihensechszylinder-Ottomotor von BMW, der erstmals 2004 im BMW 6er eingebaut wurde. m) @ 2750 rpm, 200 kW (272 PS,268 hp) @ 6700 rpm and 320 N•m @ 2750 rpm, 200 kW (272 PS,268 hp) @ 6650 rpm and 315 N•m @ 2750 rpm, 195 kW (265 PS,262 hp) @ 6650 rpm and 315 N•m @ 2750 rpm, 190 kW (258 PS,255 hp) @ 6600 rpm and 300 N•m @ 2500 rpm, 160 kW (218 PS,215 hp) @ 6200 rpm and 270 N•m @ 2500 rpm. The BMW N52 engine is a six-cylinder piston engine (NG6 generation) with two overhead camshafts (DOHC), turbocharging, the second generation Valvetronic system and the Double VANOS, which replaced the M54 engine and was produced from 2004 to 2011 in two 2.5 liter and 3.0 liter displacement variants. Suction motor / lambda = 1.0 / VALVETRONIC load control, Two chain-driven camshafts (built-up camshaft in hydroforming technology), seven bearings and finely balanced, hydraulically infinitely variable phase adjustment of intake and exhaust camshaft (doubleVANOS ), Roller rocker arm, hydraulic valve clearance compensation, VALVETRONIC, Digital motor control with integrated VALVETRONIC control MSV70; Sequential multipoint manifold injection, single ignition coils, knock control, Single pipe elbow with lightweight flange and 2 near-engine three-way main catalytic converters, Electric coolant pump; map-controlled coolant temperature, 2005-2007 E60/E61 523i (except North America), 2007-2011 E90 323i (for Canadian market only), 2010-2011 F10 523i sedan (except North America), 2009-2011 E89 Z4 sDrive23i (except North America). The wall thickness of the exhaust manifold flange could be reduced to 2 mm, making it 800 g lighter. Thread repairs exclusively with Al Helicoil. 174 bhp @5,800 rpm … While conventional coolant pumps consume up to 2 kW, the power consumption for demand-controlled control is reduced to 200 watts. Although the N20 is a four-cylinder engine, it is considered a replacement for the naturally aspirated six-cylinder N52/N53 because it powers equivalent models, producing similar horsepower to the N52/N53 with greater low-rpm torque and better efficiency. BMW switched from Nikasil-coated cylinder walls to Alusil in 1996 to eliminate the corrosion problems caused through the use of petrol or gasoline containing sulphur. The BMW N52 was an inline six-cylinder petrol engine that was available in 2.5- and 3.0-litre capacities. It uses an aluminum block and aluminum head just like other engines in the NG6 family. The valve lift is changed by means of a precise mechanism in combination with an eccentric shaft, which is set by a VDO control motor. 2006-20… Buy It Now. Torque angle. This page was last edited on 26 February 2009, at 22:17. The differences between these engines are the N52B25 has a smaller bore and stroke, so pistons, crank etc are different, but they share the same block and head. Output variances are achieved by fitting different resonant intake manifolds and variations of engine management software. 2005-2010 E83 X3 2.5si, xDrive25i (except North America).
