Available from 2004, the N52 engine replaced the M54 engine and introduced a number of mass reduction measures – at 161 kg, it was 10 kg lighter than the M54. Output variances are achieved by fitting different resonant intake manifolds and variations of engine management software. In addition, due to the high temperature of the thermostat (operating temperature – 95 degrees), the oil in them quickly breaks down and becomes coke. The three-stage resonance suction system achieves higher torque at low speeds and higher power at high speeds. the main bearings and, between the bedplate and the crankcase, a liquid Unlike its predecessor, the BMW M54 engine, this power unit is equipped with a Valvetronic valve timing system with the ability to change valve distance according to engine speed and Dual-Vanos which dynamically controls the intake and exhaust camshafts, as well as a lighter cylinder block. States that received vehicles with the N51 engine include; Arizona, California, Connecticut, District of Columbia, Maine, Maryland, Massachusetts, New Jersey, New Mexico, New York, Oregon, Pennsylvania, Rhode Island, Vermont and Washington. ©AustralianCar.Reviews. BMW has released two revisions to the piston – the third type piston, since May 2010, turned out to be the most successful and solved the problems of consumption of oil for waste. Then enter the combustion chamber. Moreover, magnesium is prone to cracking when exposed to high temperatures. 2) Under the engine hood, the emissions control information sticker will note if the vehicle is a LEV or ULEV (N52) or SULEV (N51).

Most of the carbon deposits can fall into the cylinder, paint between the cylinder walls and the piston – a spasm appears. Many BMW models (3 series, 5 series, X3, Z4 and others) went on sale with the N52 engine. The ticking noise of Hydraulic valve adjuster is a known problem with the N52 engine fitted with manufacturing date prior to November 2008. available in 2.5- and 3.0-litre capacities. Thanks to a lightweight deep-drawn flange, considerable weight reduction was achieved at the header. Higher output versions of the N52 use a three-stage variable length intake manifold (also called "DISA"). The N52 engine came with a piston that failed: the distance between the piston and cylinder was enormous.

In addition, the higher inflow rate leads to a better distribution of the gasoline-air mixture in the cylinder. 2005-2010 E60/E61 525i, 525xi (except North America), 2005-2011 E90/E91/E92/E93 325i, 325xi (except North America), 2006-2007 E90/E92/E93 325i, 325xi (North America only), 2006-2010 E60/E61 525i, 525xi (North America only), 2006-2008 BMW E85 Z4 3.0i (North America only), 2008-2011 E82/E88 125i coupe and cabriolet, 2010-2011 F25 528i Sedan (RWD only) X3 F25 28i (Both North America only, 178KW), 2008-2011 E82/E88 128i coupe and cabriolet (North America only), 2006-2011 E90/E92/E93 328i (North America only), 2008-2010 E60/E61 528i, 528xi (North America only), 2011 BMW F10 528i (North america, RWD only) 240HP (2012+ models of F10 switched to N20, xDrive was then available). The reason the BMW N52’s engine shuts down while slowing down and generally pulls weakly is a clogged catalyst, its complete failure. 2006-20… The electric coolant pump can be controlled independently of the speed of the engine according to the actual cooling demand. The lower portion of the crankcase was designed as a bedplate Therefore, you should not save on oil and change it at intervals of more than 10,000 km. Because magnesium is neither suitable as a tread material nor as a material for a coolant-carrying component, a composite construction with an AlSi17 insert and a magnesium encapsulation was developed. The N52 replaced the BMW M54 and debuted on the E90 3 Series and E63 6 Series. Many thanks. If you continue to use this site we will assume that you are happy with it. Crankcase materials are magnesium and aluminum. lol it did not even take me 5 minutes at all! The valve stem seal on the hot BMW N52 petrol engine quickly browns and oil begins to leak into the valve bag. Bmw N52 Engine Specifications The BMW N52 is a naturally aspirated straight-six petrol engine which was produced from 2004-2015. Just select your click then download button, and complete an offer to start downloading the ebook. They reach their operating temperature faster and make secondary air injection unnecessary. Alusil, when etched, will expose a very hard silicon precipitate. Conventional pumps would require up to 2 kW more power. [5] From the year 2011, the N52 began to be replaced by the BMW N20 turbocharged four-cylinder engine until production of the N52 finished in 2015.[6]. The BMW N52 was an inline six-cylinder petrol engine that was available in 2.5- and 3.0-litre capacities. Valve stem seal replacement helps. BMW dealers' first response is to perform HVA bleeding procedure, however this procedure seems not to resolve the matter. The volume-flow-controlled oil pump , whose eccentricity can be adjusted via control piston promotes only the actually required amount of oil in each operating condition. Therefore, BMW combined the N52 block to use magnesium alloy for the crankcase shell, with an aluminum “inner block” to complement the magnesium disadvantages. N52 engine cylinder liners are made of aluminum, cylinder liners are made of allusil, an aluminum alloy which is widely used as a protective shell. However, this method will not work if poor quality oil is poured into the engine or changed over long intervals. 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. Copyright © 2009 - 2020 Bavarian Autosport. The N52 debuted on the E90 330i and E63 630i. Very very different engines - N52 is actually the more advanced design, lighter with magnesium and aluminum constuction, N54 is also a 2 piece design, but an all aluminum engine, so block, heads, intake, pretty much everything is different except some of the accessories that bolt onto it, like the electric water pump, alternator etc. The BMW M54B30 engine features a cast-aluminum alloy cylinder block with cast-iron cylinder liners. Still have a question? The cylinder head cover of the engine is also made of magnesium. Therefore, the exhaled gas is not removed from the crankcase and the space under the valve cover. If a BMW N52 engine starts clinking, it’s possible oil has left the hydraulic lift. The N52 engine in various versions is installed on the following BMW cars: The BMW N52 is a DOCH inline six-cylinder piston engine in production for 11 years, from 2004 to 2015. The BMW N52 engine is a new step in the development of BMW petrol powertrains. Some high-output N52 versions were later replaced by the twin turbo BMW N54. and crankshaft main bolts; and. BAVauto.com While conventional coolant pumps consume up to 2 kW, the power consumption for demand-controlled control is reduced to 200 watts. [12], Like the M54, the N52 uses electronic throttle control and variable valve timing (double-VANOS). With a total weight of 161 kg, the 3-liter engine was the lightest six-cylinder in this performance class. This is due to a drop in the oil level in the sump or from frequent short trips. The result is a significantly improved response compared to conventional throttle-valve engines and more efficient fuel economy. An occasional ticking or rattling noise from the HVA elements may occur during cold engine starts or frequent short-distance driving, recently known after the engines reach 50,000 miles. It stops functioning if the membrane breaks. Failure to do so may very well result in the wrong parts being ordered.

Variations in power output are often due to different intake manifolds and variations of engine management software. Since 2007, the engines have been gradually replaced by replacement engines for the N53, which proved unsuitable for the North American, Australian and Malaysian markets due to the high sulfur content in the fuel. [11][15] The cylinder liners are made of Alusil[16] and a hollow camshaft is used to reduce weight. The heat management adjusts the cooling capacity independently of the engine speed via the map thermostat and the electric coolant pump. All early N52 engines inherently “ticked” at idle as hydraulic lifters served. Therefore, piston rings are very bad at removing burnt oil in the combustion chamber.
