The turbocharger is one of the most important parts that can be found under the hood of our car. It is a rotary machine consisting of a turbine and a compressor mounted on a common shaft. Its main task is to boost the internal combustion engine. The turbine of the device is powered by the exhaust gases of the engine, and the compressor supplies the engine with compressed air. How many parts does this one fly out. What are the most common causes of turbocharger failure?Turbocharger failure is one of the most serious car breakdowns that can happen to us, so we must try to avoid it at all costs. So, let's look at the most common turbocharger failures.Foreign material
Sometimes sand, stones, bolts, broken engine components, or broken switch components can get into the suction or exhaust pipe of the engine, then a malfunction occurs caused by a foreign object. This leads to bending or peeling of the turbine blades or compression wheel. Before replacing the turbocharger, make sure that the intake and exhaust systems of the engine are not clogged.The oil problem
The next most common causes of turbocharger failure are oil problems: either it is dirty or there is an oil malfunction. If the engine oil is of poor quality or if we do not remember to replace it regularly, we should take into account the appearance of deep scratches on the turbocharger bearings. In addition to dirty oil, the cause of their formation will also be a clogged or damaged oil filter or a faulty bypass valve. On the other hand, 4-5-second interruptions in the oil supply lead to burnout and polishing of the bearing surfaces. This may also be the case when the car has not been used for a long time, the oil pressure is too low, or the engine has been started incorrectly after replacing or regenerating the turbocharger. If the oil supply interruptions are longer and last about 10 seconds, this is called a lack of oil pressure. In addition to scratches, it causes technical discoloration. If we notice this, let's check if the oil pump is damaged or if the hose that lubricates the turbocharger is bent.Overheating
The last, no less dangerous cause of turbocharger failure is overheating. If the exhaust gas temperature is too high or the engine turns off too quickly after finishing work, carbon accumulates as a result of oil combustion. It burns out when a higher temperature passes from the exhaust pipe of the turbocharger to the middle part. As a result of this process, corrosion of composite bearings may occur, and individual parts may bend or crack. realescort.co.nz
