🔍 Key Concepts

• Turning gear interlock on large slow‑speed diesel engines • Relationship between turning gear position and starting air admission • Why it is dangerous to admit starting air when the turning gear is engaged

💭 Think About

• Look at how the hand lever, gears, and valve body are mechanically linked. When the lever is in the turning position, what does that do to the air path from the start air reservoir? • Ask yourself: is this device primarily affecting fuel flow, exhaust from an air motor, or the ability of starting air to reach the engine while the gears are meshed? • Which option best matches a safety interlock function that protects the engine and personnel when the crankshaft is being barred over?

✅ Before You Answer

• Verify which option actually mentions preventing engine starting under a specific condition, rather than just controlling fuel or exhaust flow in general. • Check that the illustration shows a mechanical connection between the turning gear mechanism and a valve in the start air line from the reservoir (30 bar). • Eliminate any answer choices that do not clearly describe a safety device tied to the engaged / disengaged position of the turning gear.

Which of the following statements describes the primary reason for the device shown in the illustration to be incorporated into the air start system? Illustration MO-0116

The shuttle valve compensates for any decrease in the operator's physical abilities.

The three-position valve prevents the fuel flow from reaching the fuel injection pumps.

This unit controls the air operated turning motor exhaust when the unit is in operation.

The unit shown is used to prevent starting of the main engine when the turning gear is engaged.
