🔍 Key Concepts

• Trace the piping connected to the device labeled 1 to see which system it belongs to (lube oil, jacket water, starting air, or crankcase ventilation). • Consider where combustible gases might be produced in a diesel engine and how they are safely handled. • Think about the difference between a pressure‑relief device and a venting/filtration device and where each would be located.

💭 Think About

• From the illustration, where does the line from device 1 lead, and what major component is it associated with on the right side of the drawing? • Which of the listed functions would logically require a connection to the crankcase area, and which would more likely be connected to jacket water or combustion air systems? • If the jacket water system needed a relief or chemical injection point, would it most likely be shown near the cooler (24) or somewhere else—does that match the location of 1?

✅ Before You Answer

• Verify which system boundary device 1 is drawn in: is it part of the cooling water, starting air, or crankcase/lube oil arrangement? • Check whether device 1 is connected to an enclosed space that can accumulate vapors or gases, rather than to a water-filled component. • Confirm that none of the other labeled items near the jacket water cooler (such as 25–27) already perform the pressure relief or venting functions for that cooler.

It provides a low-pressure point for combustion air filtration.

It relieves the excessive pressure developed in the jacket water cooler.

It aids in the removal of combustible gases formed in the crankcase.

It provides a low-pressure point for adding chemicals into the jacket water system.
