Teoretisk Prøve - Persontransport 1

1. Hvilken betydning har langvarig "filen" på koblingen ved igangsættelse?

Ødelægger koblingen på meget kort tid.

Ingen betydning mere, med de nye asbestfri materialer der anvendes.

Gør koblingen meget stærkere på grund af varmeudviklingen.

Gør igangsætningen meget mere behagelig, lyder godt og har ingen uheldig konsekvenser.

The correct answer states that the prolonged "slipping" of the clutch during startup will quickly damage the clutch. This implies that the continuous slipping of the clutch causes excessive wear and tear, leading to its deterioration in a short period of time.

2. Hvordan udnyttes motorens og transmissionens egenskaber optimalt?

Altid skifte gear ved mindst 2000 omdrejninger/min.

Vente med at gå ned i gear indtil motoren begynder at hakke.

Vælge gear så omdrejningerne holdes indenfor det grønne område på omdrejningstælleren.

Først skifte gear når omdrejningsbegrænseren slår fra.

The correct answer suggests that the optimal way to utilize the engine and transmission properties is by selecting gears that keep the engine revolutions within the green range on the revolution counter. This means that the engine is operating efficiently and not being overworked or underutilized. By keeping the engine revolutions within the green range, the vehicle can achieve better fuel efficiency and performance.

3. Hvilke komponenter indgår i forsyningskredsen på trykluft/mekaniske bremser?

Trykregulatoren.

Hydraulisk retarder.

ALB-Ventil.

Servopumpe.

The correct answer is Trykregulatoren. The question asks about the components included in the power supply circuit for air/mechanical brakes. Out of the given options, only the trykregulatoren (pressure regulator) is a component that is directly related to the power supply circuit for these brakes.

4. Hvilke lovkrav er der til driftsbremsen?

Driftsbremsen skal være hydraulisk.

Driftsbremsen skal være et 1-kreds bremsesystem.

Driftsbremsen skal være et 2-kreds bremsesystem.

Driftsbremsen skal være et trykluftsmekanisk bremsesystem.

The correct answer states that the drift brake should be a 2-circuit brake system. This means that the brake system should have two separate circuits that operate independently. This is important for safety reasons, as having two circuits provides redundancy in case one circuit fails. It ensures that even if there is a failure in one circuit, the other circuit can still provide braking power, reducing the risk of accidents or loss of control.

5. For at spare brændstof, bør man:

Accelerere fra 0 til marchfart, så langsomt som muligt.

Accelerere fra 0 til marchfart, forholdsvist hurtigt.

Accelerere fra 0 til marchfart, hurtigst muligt.

Undlade at opnå marchfart.

To save fuel, it is advisable to accelerate from 0 to cruising speed relatively quickly. This is because accelerating too slowly can result in the engine running at lower efficiency levels for a longer period of time, leading to higher fuel consumption. On the other hand, accelerating too quickly can also waste fuel due to increased engine power demand. Therefore, a moderate and efficient acceleration is recommended to optimize fuel efficiency.
