5 / 10

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

C) To increase the pressure inside the reservoir

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

D) To filter the air before it enters the reservoir

B) To cool the air inside the reservoir

6 / 10

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

D) Level indicator

C) Pressure gauge

B) Flow meter

7 / 10

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

D) Cooling fins

B) Pressure relief valve

C) Flow restrictor

A) Manual release valve

8 / 10

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

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

A) To regulate the temperature of the air

D) To measure the pressure inside the reservoir

C) To increase the flow rate of the air

9 / 10

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

C) To cool the engine during operation

D) To filter impurities from the air

B) To store compressed air used for starting the engine
