BMW B47D20 engine

This engine was produced from 2007 to 2017. As the main material for the cylinder block was aluminum. Of course, this engine has a diesel character. Its row, 4 cylinders and 4 valves on each cylinder for a long time do not surprise anyone. The piston stroke here is 90 millimeters. And the diameter of the cylinders is again 84 millimeters. The compression ratio is quite large, it stops at 16.5.

The volume of the engine is standard 2 liters. At 4000 rpm, its power varies from 116 to 184 horsepower. And here at 4400 rpm the power increases to 184-218 horsepower. Maximum torque at 1750-2500 rpm varies from 260 to 300 N*m. At 1750-2750 rpm it will be at 380 N*m. At 1750-3000 rpm it will be 350 N*m. At 2000-2250 rpm it can reach 400 N*m. And the maximum indicator of 450 N*m is fixed only at 1500-2500 rpm. The engine has Euro 5 and Euro 6 environmental standards. Several turbo compressors can be used in this variant. The weight of the unit will be 149 kilograms. Fuel consumption in it will be 4.1 liters on the highway, on the mixed territory 4.8 liters, but in the city about 6 liters. Oil goes somewhere 700 grams per 1000 kilometers. For the engine is suitable oil 0W-40, 0W-30, 5W-40, 5W-30. Oil in the device is about 5.2 liters. It should be changed after 7 or 8 thousand kilometers traveled. The operating temperature here is 90 degrees Celsius. The resource is tested in practice, its value is from 250 thousand kilometers. In the potential it is possible to tune the engine over 250 horsepower. The device is installed on a huge number of cars from the manufacturer BMW.

Advantages

In 2007, this diesel engine was introduced. It now used aluminum as the main material for the cylinder block. You could also notice cast iron liners, two balancer shafts on the design. Inside, however, there was a forged crankshaft and small connecting rods. From the top was installed head made of aluminum with 16 valves, it also had two camshafts. The unit featured the latest injection system and a turbo supercharger with an external intercooler. The turbine geometry could be changed at first. The timing drive is fully chain-driven, the chain being located behind the motor. The resource of this chain is calculated for the entire time for which the motor is used. But its durability and shelf life is lame. Valves of separate circulation is directed to exhaust gases. Two flywheel masses and the latest control unit were aimed at revitalizing the vehicle. In parallel, the developers also produced competing models, they constantly came to the fore and eventually replaced the unit.

Disadvantages

A noise is heard at the back of the motor. This is the most common problem, usually caused by a stretched timing chain. It usually lasts for about 100 thousand kilometers, and then you need to change it. It should be changed in time, so as not to bring additional problems to the machine. When replacing it is necessary to remove the engine, because the chain is located at the back and it is not visible.

In addition, additional sounds can cause crankshaft dampers, their life is about the same and should be replaced in time.

The flaps in the form of a vortex cannot get into the engine. The EGR system with its work gradually covers them with soot, which can lead to deplorable results. Therefore, it is necessary to blind the valves and clean the flaps with the manifold. Also drivers install plugs. You can also initially flash the block, so that then you do not have to perform all these works.

The engine also gets hot because cracks appear between the cylinders. Welding in this case does not always help, but replacement will not be cheap at all. Turbines have a resource of about 200 thousand kilometers, but sometimes there are more. If you perform maintenance in time, you can increase their life up to 300 thousand kilometers. It is necessary to change oil constantly and in time, it is recommended to use only original oil, and fuel should be poured only qualitative. In addition, you should not constantly accelerate the car to the speed limit.

Chip tuning

In order to increase the power of the motor, you need to put a modern firmware. The firmware will add from 35 to 50 horsepower, and some versions of cars and units rock up to 210 and even 220 horsepower. In the top series of BMW motor can get to 240-250 horsepower and all this thanks to Chip tuning. The weakest names of engines can be pumped to a maximum of 185 or 200 horsepower. Some versions have a firmware up to 215, and with downpipes and up to 230 horsepower. The best motor can get a stitching up to 249 horsepower and higher. And if a downpipe is used, 280 horsepower can be achieved.

Modifications

• B47D20K0 was produced from 2007 to 2012, this is the weakest modification, it has a turbine and power of 116 horsepower at 4000 rpm, torque here is 260 N*m at 1750-2750 rpm. The motor stands on 116d or 316d.
• The U0 was produced from 2007 to 2013. It has 243 horsepower at 4000 rpm, torque is 300 N*m at 1750-2750 rpm. The ECU and turbocharger help the engine to work properly, the supercharger has one and a half bar pressure. There are also solenoid injectors. The installation is used on 118d, 318d, X1, X3.
• The O0 was also produced from 2007 to 2013, it has a power output of 177 horsepower at 4000 rpm. The torque here is 340 N*m at 1750-3000 rpm. The ECU and turbo with 1.55 bar are excellent. The injectors here are piezoelectric, they have a high pressure in the ramp. Find the engine on 120d, 320d, 520d, X1, X3.
• T0 or TOP was produced in standard 2007-2013, it is the most powerful. Two turbocharged compressors blow up to 2 bar, there is a modern exhaust, piezo nozzles. Pressure in the ramp became even more, ECU is also new. It gives away 204 horsepower at 4400 rpm, torque is 400 N*m at 2000-2250 rpm. It’s on the 123d or the X1.
• The K1 or TU was produced from 2011 to 2015. It replaced its predecessors and got the latest turbo. This motor has more fuel efficiency than before, the consumption has been reduced by 3 percent too. There is 116 horsepower at 4,000 rpm and 260 N*m of torque at 2,500 rpm. The engine is in the 116d, 316d, X1.

There’s also U1, O1, T1, U1, they’re pretty much no different from their predecessors.
