  1. Question 1

    Can too high viscosity cause damages to the fuel injection system?
    • It can only affect the atomisation.
    • It cannot cause any damages.
    • It can damage parts of the fuel pump and their drive, it can cause the relief valves to spray off, and it can affect the atomisation of the fuel.

  2. Question 2

    If an input value of a temperature controller connected to a heater is above the set point, this will result in:
    • A reduction of the output signal.
    • An increase of the output signal.
    • A stabilization of the output signal above the proportional band.
    • A narrowing of the proportional band.

  3. Question 3

    Select the components that are in your opinion the main components in a steam viscosity system:
    • Measuring tube built into fuel line, and provided with a thermometer and manometer.
    • Flow rate regulator.
    • Differential pressure converter.
    • Controller (proportional, proportional + integral or proportional + integral + differential).
    • Steam regulating valve.
    • Viscosensor.

  4. Question 4

    What are the highest viscosity modern diesel engines are capable of burning?
    • Approximately 1 200 cSt, at 50 °C.
    • Approximately 700 cSt, at 50 °C.
    • Approximately 500 cSt, at 50 °C.
    • Approximately 1 000 cSt, at 50 °C.

  5. Question 5

    What determines the oil's viscosity?
    • The oil's content of cat fines.
    • The oil's content of sediments.
    • Only the temperature.
    • Temperature and composition.
