The development of the power of a turbocharged diesel engine is influenced by the setting and adjustment of the following engine systems: power system, fuel mixture preparation, the moment of fuel injection into the cylinder (ignition). And also the work of turbocharging.

Step 1
In turn, the functioning of the systems as a whole depends on the serviceability and adjustment of each element in particular. For example, a malfunction of the turbocharger, which includes: a turbine, a line for intake of air and supplying it to the injection pipeline, electronic oil and air pressure sensors, a turbine shut-off valve, and so on.
Step 2
In the event of failure of any device or device, a command will be sent from the electronic control unit that will turn off the turbine, and the engine will no longer be able to develop maximum power.
Step 3
In addition, the crankshaft revolutions will be reduced to three thousand per minute, which will make it impossible for the further operation of the car.
Step 4
In the event of such problems, first of all, a fault diagnosis is performed. By connecting the scanner to a special connector on the car, the service center specialist will be able to determine the reason for the turbine shutdown.
Step 5
As a rule, the fault for turning off the turbocharging lies either with the charge air pressure sensor, or on the turbine itself, which may have exhausted its engine life.
Step 6
A preliminary check of the turbine serviceability is carried out without removing it from the engine.
Step 7
For this purpose, a special device with a pressure gauge is connected to the outlet of the turbine, which determines the pressure of the air pumped by it when the engine is running.
Step 8
All further actions depend on the readings of the pressure gauge, either the turbine is dismantled and replaced with a new spare part or repaired, or the search for faults in its other mechanical components continues. For example, a decrease in air pressure can occur due to a torn or exfoliated from the inside of the rubber pipe connecting the turbocharger injection line.
