(a) Engine fails to start. (4)

(b) Engine does not reverse. (4)

(d) Engine runs unevenly. (4)

Reference Answer

### (a) Engine Fails to Start
**Reasons & Solutions:** The failure of a marine diesel engine to start can be attributed to issues within the starting air system, control system interlocks, or the engine's mechanical condition. A systematic approach is required for troubleshooting.
* **Insufficient Starting Air:**
* **Reason:** The primary cause is often low pressure in the main air receivers (bottles) or an inadvertently closed main airline valve (e.g., bottle isolating valve, automatic valve). A damaged bursting diaphragm on the start airline can also lead to a complete loss of pressure.
