A) Fuel injector

D) Oil separator

2 / 10

Why is a fusible plug included as a mounting on a starting air reservoir?

B) To allow manual release of pressure

A) To provide a visual indication of pressure

D) To filter the air entering the reservoir

C) To melt at a specific temperature and release air in case of a fire, preventing an explosion

3 / 10

What is the purpose of an inspection cover on a starting air reservoir?

D) To filter the air before it enters the reservoir

A) To allow visual inspection and maintenance of the interior of the reservoir

B) To cool the air inside the reservoir

C) To increase the pressure inside the reservoir

4 / 10

Which of the following is a commonly used coating to protect the interior surface of a large air reservoir against corrosion?

5 / 10

What safety feature is used to ensure that the starting air reservoir is not over-pressurized during filling?

D) Cooling fins

A) Manual release valve

B) Pressure relief valve

C) Flow restrictor

6 / 10

What is the purpose of a drain valve on a starting air reservoir?

A) To fill the reservoir with compressed air

D) To connect the reservoir to the air compressor

B) To remove accumulated moisture (condensate) from the bottom of the reservoir

C) To release air during engine startup

7 / 10

What is the primary function of a starting air reservoir in a marine engine system?

D) To filter impurities from the air

A) To store fuel for the engine

B) To store compressed air used for starting the engine

C) To cool the engine during operation

8 / 10

Which mounting on a starting air reservoir indicates the pressure level inside the reservoir?

B) Flow meter

D) Level indicator

C) Pressure gauge

A) Temperature gauge

9 / 10

Which other coating can be applied to the interior of a large air reservoir to prevent corrosion?

D) Wood varnish

C) Rubber lining

B) Copper plating

A) Zinc-based coating (galvanization)

10 / 10

What is the function of a non-return valve on the starting air reservoir?

A) To regulate the temperature of the air

C) To increase the flow rate of the air

B) To prevent backflow of air into the compressor, ensuring that the air remains in the reservoir

D) To measure the pressure inside the reservoir
