Golovna Purchase and sales Before the release of the restyled version of the BMW X3 Facelift 2014, a new generation of diesel engines was introduced, which may soon become an invisible part of the European BMW fleet. The B47 engine, like its successor N47, has a cylinder capacity of 2.0 liters of displacement. Numerical improvements are aimed at reducing engine costs and improving the sound of the motor.

In one of the interviews, Christian Bock, who is completing a project to develop a new engine, reveals information about the rich technical features new 4-cylinder

diesel unit

, which is applied to options with 150 and 190 k.s.

It is impossible to overestimate the importance of a budget, or powerful, diesel engine for the European market.

For example, the 520d engine has been popular in the BMW 5 Series for a long time, and is even more popular in the 3 Series and models increased flow rate You will demonstrate a dying appetite in practice, as soon as you get to know it.

In addition to the X3 sDrive18d, tires with low support ensured that the car achieved 4.7 liters per 100 km in the standard cycle and the status of the most economical commuter in its class.

It is possible to say one: the dvigun b47 postpovo paste the n47 і signs of the dovo of the gibberry of the productiveness of the vitrat Paliva, not that restyle -verbage x3, but the Bavashny Bavarsky Automobilam. Proteus, in the opinion of the BMW company, its main advantage lies elsewhere. Adapted from the N47, the new B47 has a lot more unified parts, which allows them to be purchased in large quantities, significantly reducing purchasing prices.

With the launch of the new, slightly repainted 3-Series, Bayerische Motoren Werke, bringing the decoy to its heights.

For example, in Europe New model 330i will replace the 328i in front, otherwise it will be purely nominal, since the engine will not change its volume and will still be 2.0 liters.

I remember that there were many other hours when everything was different. Everything was much simpler and intuitively clearer. The 328i model has a 2.8 liter engine under the hood, and the 330i, of course, has a 3.0 liter engine under the hood. And so on, then, beyond the face value. Due to the logic of speeches, such a “detail” is not random and is often justified.

The volume of engines, incredibly, is becoming more modest, but the pressure... the pressure is suddenly growing, and at an even rapid pace. You won’t even bother to look around, but the new model will bypass the crowd by a couple of tens of horsepower. Over a decade of continuous progress, engines that were popular in the early 90s with small cars, 1.6, 1.8 and 2.0

To understand the breadth of changes in the BMW engine nomenclature, we will try to understand which Top 5 BMW engines have been installed on 3-Series cars for many years.

Including "M" models.

5 - BMW M42 B18, 1.8 liters, in-line 4-cylinder, 138 liters.

With. (E30, E36) Finally, we took the place with a rich 1.8 liter BMW unit. Quiet, quiet, don't marry the horses! We understand that you may not be from Bavaria, but listen to us. First of all, were you victorious? Lightweight bodies have the e30 and e36, most often the 318iS models. We know, but not the same best BMW in terms of dynamics and drive (it has already happened that

BMW vlasniks Give this bitter “drive” to everyone, but the 1.8-liter engine still achieves its mission. For a reasonable price, you got a sports car with a wide range of upgrade options and stock dynamics of a little more than 10 seconds. For the end of the 80s, the first half of the 90s according to reference

a valuable river.

The Bavarians brought vidchuttya

Why didn’t the Germans expand their success further and establish a model for expansion to other continents?

It’s because the idea was more important for the couples, because cool car BMW with whatever creations.

It is powered by an M54 DOHC inline six-cylinder engine, a cast aluminum block and a solid aluminum cylinder head. Wines are individual throttle valves

for the skin cylinder, lighter pistons, larger inlet valves, a VANOS gas-pressure phase change system for high-pressure gas injection, the list of advanced technical solutions is not exhaustive, and can be continued for a long time. The S54 is not far removed from BMW's racing engines and is the remaining naturally aspirated engine found in the M3. The pressure was sufficient to accelerate the M3 from 0 to 100 km/year in 5.1 seconds,

maximum speed

limited to 250 km/year.

BMW X5 F15 BMW 520d GT F07 Mini Cooper Reliability, problems and repair of the BMW N47 engine.
In addition to its predecessor, the N47 features a new lightweight closed aluminum cylinder block with cylinder liners, two balancer shafts and a cylinder diameter of 84 mm.
In the middle of the block there is a forged crankshaft with a piston stroke of 90 mm and forged connecting rods. The compression height of the pistons is 47 mm, and the compression stage is 16.5. The water immediately gave a working volume of 2 liters.
On top of the block is an aluminum 16-valve head with two split shafts. The diameter of the intake valves is 27.2 mm, the exhaust valve is 24.6 mm, and the thickness of the valve stem is 5 mm. BMW N47 engines removed the boost system

Common rail The turbine on the first versions (116 hp and 143 hp) was installed using a Garrett GTB1749VK with variable geometry..

The timing drive here is lancet and the lancet is rotating behind the engine.

The timing life of the timing belt on N47 is covered for the entire service life of the engine, but there is no real longevity, problems with the timing belt are written below.

There is also a shut-off valve for the recirculation of processed gases,
dual mas flywheel This block is Bosch DDE7.0/DDE 7.1. In parallel with this engine, a version with a working volume of 1.6 liters - N47D16, as well as a 6-cylinder Motor N57 diesel N57
Since 2014, the N47 engine was gradually replaced by the current B47 diesel engine. Modifications of the BMW N47 engine 1. N47D20K0 (2007 - 2012) - the weakest version of the N47 with a Garrett GTB1749VK turbine.
Tension 116 k.s. at 4000 rpm, torque, what to turn, 260 Nm at 1750-2500 rpm. This engine is built for BMW 116d E87 and 316d E90. 2. N47D20U0 (2007 - 2013) - tension version 143 k.s. version with two turbochargers BorgWarner KP35 and K16, boost pressure 2 barg, there is also a new exhaust, piezo injectors with a stronger pressure at the ramp, and a modified ECU with DDE 7.1.
The output of the N47 TOP is 204 hp.
at 4400 rpm, torque, what to turn, 400 Nm at 2000-2250 rpm.
These engines were installed on the BMW 123d E87 and X1 E84. 5. N47D20K1 / N47TU (2011 - 2015) - motor replacing N47D20K0. An IHI RHV4-T39 turbine and ECU DDE7.1 are installed here.
Aligned with the front, the engine is more economical, fuel consumption is reduced by 3%. Tension 116 k.s. at 4000 rpm, torque, what to turn, 260 Nm at 2500 rpm.
You can find this engine under the hood of the BMW 116d F20, 316d F30 and X1 E84.

6. N47D20U1 / N47TU (2011 - 2015) - motor, replacing N47D20U0.

1. Noise from the rear of the engine.
The most common problem is N47, which is caused by the extended timing belt, and the service life is almost 100 thousand. km. Often the problem arises much earlier. There is only one solution - replacement and pulling on it is not good, otherwise damage may occur.
The additional disadvantage of replacing the lance on the N47 diesel engine is due to the need to remove the engine, because the lance is retracted from the rear.

In engines up to 2009, the crankshaft must be changed at the same time.
2. More outside sounds You can use the crankshaft damper and serve for about 100 thousand. km, an hour more, then it will require replacement.
3. Vortex dampers. By analogy with the M47, here a swirl flap is installed in the intake manifold, but instead of the same M47, stinks cannot be absorbed into the engine. It’s no less true that due to the operation of the EDR system, the flaps can become completely covered with carbon deposits.

To prevent this from happening, it’s best to shut off the EGR valve and clean the flaps together with the manifold, or even better, remove them and install plugs.

In order for the engine to operate perfectly adequately, after this operation it is necessary to flash the control unit under the robot without any benefit.

In addition, overheating of this engine can lead to cracks in the block between the cylinders, which you can try to weld, otherwise it will not help and you will end up tearing the cylinder block without repair.

N47 should be kept aside for maintenance and if illnesses occur frequently, and may exceed 250-300 thousand. km and more.
To reduce the risk of problems with the engine, change it more often

BMW N47 engine tuning Chip tuning: whatever you want and fold for your time, but tighter and more reliable units A from line N, As it came to replace them, nothing was created for the service. So, for example, all N series engines have an oil dipstick. The sensor is often flawed, causing oil consumption to average 1 liter per thousand km. Result - – too much hunger.

And at the same time, the N-series motors themselves were repeatedly recognized as the best in prestigious competitions in various nominations.

Marvelous. N45 This engine was produced from 2004 to 2011 and installed in the BMW 116i, BMW 316i (E90), BMW 320si.

Vidomy is always at fault for his unpretentiousness with a modest yield, especially in the 1.6-liter Viconn. Intermittent operation and trouble with the timing drive have, unfortunately, become its characteristic problems. Moreover, the problem stretching the lantsyug and yogo jump

A few lines were not allowed to appear before the serial release of N45.

In addition, the 320si series vehicles with this engine were repaired with cracks in the cylinder block - through an insufficiently thick wall between them.

The latest list of victims looks like this: BMW 120i, BMW 318i, 320i, BMW X3 2.0i.

At first I felt nothing - 4 cylinders, modest 156 hp, naturally aspirated. But the attempt to promote economy while saving effort did not lead to any good. The designers put everything into the N46 that was available to the auto industry at that time. Here you have a throttle-free intake, a phase control system, and extreme operating temperatures. Transfer bag: coking of oil in the grooves piston rings

and wear of oil pans.

The result is supernatural unpretentiousness and

. All of a sudden the plastic washers on the timing drive fall apart and just crash into the engine crankcase. There is also a quick way out of the hydraulic system - major repairs can be completed after only 3-4 years of operation.

In the worst way.

Vlasniks from afar worked hard to get ahead, pouring AI-98 and changing oil as often as possible.

• Ale only helped at this stage.
• N63 4.4 Biturbo
• These “hot” engines have been installed since 2008 on a lot of models: BMW 750i/Li, BMW X5/X6 50i, BMW X6 ActiveHybrid, BMW 550i, BMW 650i.
• Basically, the N63 4.4 Biturbo is a problem with the cooling of the V-shaped block.
