Crankcase pressure measurement

The BTS Turbocharger Diagnostic Tool offers you the possibility to measure the crankcase pressure in a simple way. Especially the increasing requirements and the more complex vehicle technology makes it indispensable to check the pressures even while driving. Our diagnostic tool is able to measure the pressure in the negative as well as in the positive range to an accuracy of one millibar. Due to the supplied adapters for the oil filler neck, the pressure measurement can be carried out in almost all passenger cars. Special additional adapters can be easily ordered.

Problems with the crankcase pressure are often manifested by oil loss at the turbocharger. The increased pressure causes a resistance in the oil drain line of the turbocharger, thus the oil can no longer drain freely back into the oil pan. The oil is then forced through the turbocharger into the exhaust system or intake line, even if the seal is intact. Added filter elements can ensure that oil mist enters the intake upstream of the turbocharger via the exhaust hose of the crankcase ventilation.

Measurement of the exhaust gas back pressure

The turbocharger diagnostic tool can also be used to measure the exhaust backpressure while driving. This measurement is very important, as you often cannot rely on the values read out in the engine control unit. Due to the design, it can happen that the differential pressure sensor shows you a value that is too low, which unfortunately is not correct. For this very reason, it is very important to determine the actual pressure again with a special measurement.

Excessive exhaust backpressure can cause damage or even failure of the turbocharger. Excessive exhaust backpressure causes temperatures in the turbocharger to rise, which places enormous stress on the material of the charger. In addition, the risk of coking oil and an oil fire in the bearing is increased. Furthermore, an axial thrust occurs at the turbine shaft, which results in increased wear of the axial bearing in the turbocharger, up to bearing damage or total failure of the turbocharger. Oil leakage can also occur on the compressor side due to the uneven pressure conditions. This results in unclean combustion and a heavily sooty engine.

Testing the pneumatic boost pressure control

With the turbocharger diagnostic tool, you can not only measure the crankcase and exhaust backpressure, but also check the function of the pneumatic boost pressure control. To do this, disconnect the hose from the turbocharger's control box and insert the pressure gauge into the system using the T-piece supplied. The control pressure of the control box and the function of the vacuum pump or solenoid valve can then be checked. This check is also possible during operation.
