BMW M62B44 engine

The M62B44 engine replaced the familiar M60B40 engine in 1996. All motors of the M60 range were replaced by modified versions of the M62 series engines.The M60B40 engine was used as the basis for the creation of this motor. This power unit had 4.4 liters of working volume, thanks to the installation of the cylinder block under the increased diameters of the combustion chamber. In the first versions of the motor were installed nikasil liners, and after 1998 they were replaced by alusil. The engine was equipped with a new crankshaft, which was characterized by increased stroke length and the presence of six counterweights. The connecting rods were installed from the previous motor. The pistons were also replaced, which were distinguished by a new diameter of 92 millimeters.

The M62B44 engine had similar cylinder heads to the M60 range. The only difference was a change in the characteristics of the camshafts. The valves used on this motor were not changed. Differences also consisted in the installation of a cylinder head cover made of magnesium, lightened springs and plates. M62B44, the characteristics of which were quite impressive, was characterized by the installation of a single-row timing chain. Unlike the previous engine, which was equipped with a double chain, the life of this version often exceeded 200 thousand kilometers of mileage.

The M62b44 motor, tuning of which is described below, was also characterized by the installation of new throttle plates. The intake manifold also received changes. The applied ignition coils had practically no differences from those installed on M52 engines. An innovation was the use of a programmable thermostat. The engine control unit used was Bosch DME M5.2.

The specifications of the M62B44 powertrain, reviews of which are provided below, were slightly changed in 1998. Until then, the M62B44 was produced without vanos, but now the motors were accompanied by a VANOS system. With the additions should also be noted the installation of electronic throttle, intake manifold with a reduced diameter of the channels, and the replacement of the old electronic control unit for a new – Bosch DME M7.2. The finalized engine was labeled M62TUB44. This engine was installed on cars of the German concern, having the index 40i. Differences from the M62B44TU and reviews of the standard engine are described here. M62B44 with mkpp served as a base model for the creation of a less powerful power unit M62B35 with a working volume of 3.5 liters, as well as a more voluminous motor M62B46, which provided 4.6 liters of volume.

In 2001, the production of 8-cylinder engines with V configuration started, which began to supplant the previous lineup. The N62B44 engine began to gradually squeeze the M62B44 power unit out of the automobile market.

Disadvantages

The engine may develop foreign noises. Such troubles may be caused by the fact that the chain tensioner has broken or the chain itself has stretched, as its life does not exceed 200 thousand kilometers. Such troubles can be caused by the Vanos system, which is characterized by the same resource of work. In case of such troubles, they should be urgently eliminated, as it may lead to more serious failures.

Leaks are not uncommon problems on these power units. The valve cover gasket can wear out, so it is worth replacing it. The antifreeze or other coolant bath can also fail. In this case, the intake manifold gaskets, pump and the bathtub itself must be replaced.

The engine can run unevenly and upset its owners with floating revolutions. Basically, these problems are caused by the fact that the operation of the kvkkg is not performed correctly, so a large number of motorists are interested in whether it is possible to put an oil trap on the M62B44 motor instead of the kvkkg. Also, this malfunction can be caused by contamination of the throttle plates, their position sensor or failure of the air flow meter.

There are almost no differences in the M62B44 and M62B46 attachments, so these power units have similar failures associated with increased oil consumption after 250 thousand kilometers of mileage. This problem can be eliminated by replacing the oil sealing caps.

After 200 thousand kilometers, the engine cushions can also fail, and the generator can also come. The problems are quite impressive, but they all appear after a high mileage, so they are quite acceptable.

Many people are interested in the length of the BMW X5 2000g M62B44 oil dipstick, as it is located in an ambiguous place and can fly out on the road. BMW E39 M62B44 caliper is also wanted by a lot of drivers.

Only quality oil, which is prescribed by the manufacturer, should be used to fill the power unit. Regular maintenance, competent care and quality filling fluids can guarantee an impressive resource and smooth operation of the engine. In any case, if the breakdown is serious, you can always order a contract motor from Japan BMW M62B44 for a small fee.

Tuning

If your car is equipped with an M62TU power unit with vanos, the first thing to do is to replace the exhaust manifold. The standard part from the base power unit is installed, which is characterized by a larger diameter of the channels. Without replacing the camshafts to more evil also can not do without. It remains only to add a sports intake system and install new software. After these actions it is possible to get about 330 forces. Classic software replacement on a standard motor is not enough, and it is not expedient.

Often performed swap engine BMW e46 M62B44, as the installation of a compressor on the motor allows you to increase its power to 400 horsepower, and sometimes more. On the automotive market there is a huge number of specialized kits that can be installed without replacing the piston. But their cost is quite large, so you will have to prepare money. After buying a whale, it remains only to install a Bosch 044 pump, adjust the pressure of half a bar, and you can safely remove the power of 400-plus forces. Building a turbocharged engine is very difficult and expensive, so it’s easier to just swap your car for a BMW M5.

This engine is installed on the following models:

BMW 5-Series (E39)

BMW 8-Series (E31)
