MDE 4 Q5

1 / 4

Question: What is the primary purpose of the diffuser in the construction of a diesel engine turbocharger?

C) To slow down the high-velocity air exiting the compressor and convert kinetic energy into increased pressure

D) To filter out impurities from the intake air before it reaches the compressor

B) To reduce the pressure of the exhaust gases before they reach the turbine wheel

A) To increase the temperature of the compressed air before it enters the intake manifold

2 / 4

Question: What is the primary purpose of the thrust bearing in the construction of a diesel engine turbocharger?

A) To support the radial load of the rotating components and reduce friction

B) To absorb and manage the axial forces generated by the high-speed rotation of the turbocharger shaft

D) To increase the intake air pressure before it reaches the engine cylinders

C) To cool the turbocharger by directing airflow through the bearing housing

3 / 4

Question: What is the primary purpose of the inducer in the construction of a diesel engine turbocharger?

C) To increase the temperature of the intake air for better combustion

D) To enhance the flow of lubricating oil to the turbocharger bearings

A) To direct the exhaust gases onto the turbine wheel for efficient energy extraction

B) To draw in and compress the intake air before it enters the compressor wheel

4 / 4

Question: What is the primary purpose of labyrinth glands in the construction of a diesel engine turbocharger?

C) To cool the turbocharger by circulating coolant around the bearings

B) To prevent the leakage of lubricating oil and seal the gap between the rotating shaft and stationary components

A) To provide additional lubrication to the turbocharger bearings

D) To increase the intake air pressure before it reaches the compressor wheel
