BMW M54B22 engine

This engine was produced from 2001 to 2006 and managed to please many car enthusiasts. Its cylinder block is made of aluminum. As a power system, the proven injector is also used. The inline type allows the apparatus to perform its work more qualitatively. There are 6 cylinders, and each of them has 4 valves. The stroke of the piston pleased the drivers, because it was only 72 millimeters. But the diameter of the cylinder in this case was about 80 millimeters. The compression ratio of this model reaches a considerable 10.8. The volume of this engine will be almost 2.2 liters. Its power at 6100 rpm is 170 horsepower. And the maximum torque at 3500 rpm will be 210 N*m. Here you also need to use at least 95 gasoline.

But for environmental norms, there is a Euro 3-4 system. The engine weighs about 130 kilograms. In urban areas, gasoline consumption here reaches as much as 13 liters per 100 kilometers, on the highway the car will go much quieter and take about 6.8 liters per 100 kilometers. And on a mixed distance the consumption averages 9 liters per 100 kilometers. Oil goes also almost 1000 grams per 1000 kilometers. For the engine is suitable oil 5W-40 and 5W-30. There is more oil in the engine than in previous versions, here it is 6.5 liters. Replacement is recommended every 10 thousand kilometers. The operating temperature of the engine is about 95 degrees, and the resource in practical conditions will be about 300 thousand kilometers. Potentially, tuning can give more than 250 horsepower.

M54B22 engine specifications

Advantages

This engine is the youngest in its series, but it is not the worst. It evolved from previous models. In order to bring all the parameters to normal, the developers replaced here the crankshaft with a modern crankshaft, which was made of cast iron. The stroke was now 72 millimeters. Small pistons, modified connecting rods with forging and the size of 145 millimeters helped to cope with the loads. The cylinder block was unchanged, made of aluminum and had cast iron liners.

The head of the cylinder block was similar to similar versions of other models. The intake manifold was completely replaced, it became shorter and received huge channels. The control system from Siemens received an updated version with improved functions. The throttle slide has a diameter of 62 millimeters and was used for the first time in similar models.

BMWs with 20i indexes were most suitable for such a motor. In 2006, the developers removed the engine from production and replaced it with a new one with four cylinders. In-line sixes came to replace the units with a small volume, but later gave way in the market to the next class.

Disadvantages

Oil consumption is still high. The culprit of this problem is the piston rings, which have the ability to skew sideways. Here only the purchase of new rings will help, even parts from other similar models will do. Drivers often check the valves with ventilation of crankcase gases. It often annoys car owners and it may also need to be replaced periodically.

The engine overheats, often due to a clogged radiator. A good quality cleaning and blowing out the air in the cooling system helps a lot to solve the problem. You should also check the pumps, radiator cap or thermostat.

The ignition sometimes works intermittently. This problem is present on several car models. Hydraulic compensators in this case receive too much coke and cannot cope with the load. Buying new parts very often solves the problem.

The red oil light can sometimes come on. This occurs either in the oil cup or in the oil pump. And camshaft position sensors can often fail too. The bolt threads in the cylinder block and cylinder head are not very reliable and require careful handling. The thermostat cannot last for a long time, and there are huge requirements and recommendations for engine oil. The uninterrupted life of the engine is not very good, but almost all indicators here are an order of magnitude higher than the previous model. The apparatus has received good reliability, its power pays off, and for a swap the best choice simply can not be found. Specialists give the engine very good marks, and drivers say that they like the parts.

Modifications

This model does not include changes and modifications, because its structure is much more complex than its competitors.

Chip tuning

In order to improve this engine, you can increase the amount of work. It is necessary to buy a crankshaft and connecting rods from models with more help, and leave the pistons unchanged. The cylinder-head gasket should be thick, and the control system is fully customized for increased resource consumption. All this will add about 20 horsepower to the total power, which can be felt quite well on the highway.

This motor can also be turbocharged, and you can often find compressor kits that will help greatly with this operation. This part will give more than 250 horsepower per piston standard. True the price of such an undertaking is quite high and is not available to all users. Therefore, a modern engine will be a much better solution for car owners, because its cost will be less than improving the current one.

This engine is installed on the following models:

BMW 3-Series (E46)

BMW 5-Series (E60)

BMW 5-Series (E39)
