00:00:00,000 --> 00:00:05,375
The lubricating oil system includes a pre-lube pump and a check valve.

2
00:00:05,375 --> 00:00:11,250
 The pre-lube pump operates prior to engine cranking to circulate lubricating oil through the engine.

3
00:00:11,250 --> 00:00:19,958
 This is critical to engine protection at low temperature operation, when the oil viscosity is high and oil flow characteristics are poor.

4
00:00:19,958 --> 00:00:25,500
 Pre-lube pump operation is automatic and is controlled by the locomotive control system.

5
00:00:25,500 --> 00:00:35,792
 Once the pump is activated, the ELIT and ELIP sensors in the ECU monitor the temperature and pressure of the lubricating oil entering the engine.
