BMW M57D30TU engine

The M57D30TU is a diesel powertrain that provides a maximum output of 204 to 286 horsepower depending on the modification, with a displacement of 3 liters. This motor can be found under the hood of the BMW third series and fifth series, as well as many other cars.

Advantages

The year 2002 was marked by the appearance of a new line of power units under the hood of cars, which had the marking M57D30TU. The working volume of this power unit was exactly 3 liters. Such indicators are provided due to the use of increased piston stroke in the cylinders up to 90 millimeters. In the design of the power unit used a new version of supercharger Garrett GT2260V in combination with an electronic control unit power unit DDE5.

The lineup also includes a modification M57TUD30TOP, which is considered the most powerful. The Bavarians managed to achieve such indicators thanks to the use of a pair of turbines, differing in size, BorgWarner KP39 and K26. With the help of two superchargers it is possible to provide an operating pressure of 1.85 bar. This motor achieves a compression ratio of 16.5 to 1. Later, this power unit was replaced by an improved M57D30TOPTU engine.

All power units are characterized by the use of an electronic impeller geometry control system. As a power supply system, the design provides for direct Common Rail fuel injection, in which there is a pressure accumulator. The presence of a standard intercooler makes it possible to increase the amount of air blown into the engine.

The lubricant level is monitored by electronic sensors. A piezoelectric injector located in the supply system is used to ensure that the correct amount of fuel is delivered into the combustion chamber. This also has a positive effect on fuel consumption and emissions.

In order for the motors to provide the required emission rates, the designers applied in their design intake manifolds, which are equipped with vortex flaps. The work is that the low speed of the crankshaft, entails the closure of one of the intake channels with the help of a flap. As a result, the quality of the mixture is improved and greater combustion efficiency is achieved.

Disadvantages

The use of an intake manifold with swirl flaps has entailed more than just positive aspects. Owners of cars with such power units often encounter problems when the flaps break off and fall into the engine. This leads to the engine not running at all. It is best to remove the problematic units as soon as possible, and also install plugs instead. After that it is necessary to adjust the electronic control unit for normal operation without these devices.

During operation of the power unit, extraneous noises may appear, as well as strong knocks. This problem is present in almost all motors and is caused by the crankshaft damper. It is necessary to check the condition of the unit, and replace it if necessary.

The desired traction may be lost and an exhaust odor may be heard inside the passenger compartment. Often, the cause of this problem can be a crack formed in the intake manifold. It is best to replace it with a modification from the M57D30 engine, made of cast iron.

The resource of the engine fuel injectors is about 100 thousand kilometers. Turbines do not cause problems for owners of cars with such power units under the hood. Subject to the use of original high-quality oil, turbines can serve more than 400 thousand kilometers.

Diesel power unit M57D30TU is characterized by quite a lot of reliability, and also serves for quite a long time, only it is necessary to maintain it properly, use only quality fuel and lubricant. The use of quality fuel is especially important, as the fuel system can break down very quickly. If you adhere to all the norms of operation, the resource of the M57D30 can overcome the indicators of 500 thousand kilometers.

Modifications

1. The M57D30O0 is the base powertrain of the M57D30, which was produced from 1998 to 2003, and was characterized by the installation of a Garett GT2556V turbine. Its maximum output at 4,000 rpm is 184 horsepower, and at 1,750 rpm a torque figure of 390 Nm can be achieved.
2. The M57D30O0 was produced from 2000 to 2004, and is the version with slightly more power. Its maximum output is 193 horsepower at 4,000 rpm, and the maximum torque is 410 Nm at 1,750 rpm.
3. The M57D30T1 / M57TUTOP was produced from 2004 to 2007. This is the maximum version of the M57TU, which differs from the standard engines by installing two BorgWarner BV39 + K26 turbos, resulting in a maximum output of 272 horsepower at 4.4 thousand rpm, and peak torque of 560 Nm at 2 thousand rpm.
4. M57D30U2 / M57TU2 – this engine was released as a replacement for the M57D25, and was produced from 2006 to 2010. The main difference is the use of aluminum cylinder head, as well as modification of the standard fuel supply system, which allowed to ensure compliance with Euro-4 standards. The engine has a power of 197 horsepower and maximum torque of 400 Nm.
5. M57D30O2 / M57TU2 – motor produced from 2005 to 2008. The model was characterized by a maximum output of 231 horsepower, as well as a maximum torque of 500 Nm.
6. The M57D30O2 / M57TU2 is an engine that was produced from 2007 to 2010 and also allowed a maximum output of 235 horsepower as well as a peak torque of 500 Nm.
7. M57D30T2 / M57TU2TOP – the last modification, which was produced from 2006 to 2012. This is the most powerful variation of the motor of the M57 range. A distinctive feature is the installation of a pair of BorgWarner KP39 + K26 turbines. The maximum power of the motor is 286 horses, and the torque reaches 580 Nm.

Technical specifications

Motors belonging to the M57 series began to be installed under the hoods of Munich cars from 1998, and was intended to replace the M51 diesel engine. The predecessor was used as the basis for the development of this motor. It is similar in that it uses a cast iron cylinder block, but the cylinders themselves have an increased diameter of 84 millimeters. Inside the block there is a crankshaft, providing a piston stroke of 88 millimeters, connecting rods are quite large – 135 millimeters. Pistons are characterized by a compression height of 47 millimeters. All this design is distinguished by a working volume of 3 liters.

The entire structure is covered with an aluminum cylinder head, arranged according to the DOHC system, which provides 24 valves on the power unit. Inlet and exhaust valves do not differ in size – all are 26 millimeters. The valve feet are 6 millimeters each. The valves and springs are the same as on the related M47 diesel engine, which has 4 cylinders.

The camshafts are driven by the timing chain, which has a long service life. And with proper use and maintenance, the chain will not need to be replaced at all.

The M57D30TU is an updated version of the engine that has been in production since 2002. The working volume of this engine has been raised to 3000 cubic centimeters, thanks to the installation of a crankshaft with a piston stroke of 90 millimeters. The turbine was replaced by a Garrett GT2260V, and the electronic engine control unit was DDE5.

In addition to producing a huge number of different modifications, the M57D30 was chosen as the basis for the 2.5 liter version of the M57D25. Production of the motor was finished in 2012, but it started to be replaced by a new diesel engine from 2008.

Tuning

These powertrains have a pretty good propensity for modernization. A simple software change will provide a 40 horsepower boost, and installing a downpipe will provide another 10-20 horsepower boost.

This engine is installed on the following models:

BMW 3-Series (E46)

BMW 5-Series (E61)
