| Title | Part 21 - Emergency Diesel Generator Cylinder Liner Leak |
| Event Description | The following is a synopsis of information provided by Engine Systems, Inc. (ESI) via fax and email:
On February 22, 2024, an EMD brand cylinder liner developed a jacket water leak following installation on an emergency diesel generator set. The leak occurred at a brazed joint and was detected after post-installation engine testing. Had the leak gone undetected, jacket water may have accumulated in the combustion chamber or airbox and potentially contaminated the engines lubricating oil. Jacket water intrusion into any of these areas is undesirable and could lead to failure of the diesel engine and therefore failure of the emergency diesel generator set. The extent of condition is a single cylinder liner, P/N 9318833, S/N 20D6294 used in the power assembly shown below.
