A the beginning - on the side those are blow-down valves. The tractor is driving the diesel through it Power takeoff. Normally - before engaging the starting system - those are opened. Run the start system briefly- blow any water and moisture out of the cylinder. Stop the starting system. Close the blow down valves. reengage starting system and you will start. With blow-down valves open - inadequate compression for engine to start.
I know it's been a long time. But I've read that repeatedly and was wondering: Why is there such a problematic amount of moisture/water in (some?) locomotive engines? Where is it coming from? Didn't have any luck getting a clear answer yet, you seem like you might know.
@@heinzhaupthaar5590 It's not just locomotive, any big industrial engine can accumulate condensation. You have 15-20 tons of hot/warm steel that has to cool at some point (mostly at the end of the day when it's cold) and if the conditions are met, you can have quite substantial accumulation of water around and inside the engine. Any object that is warm and set in a cool, humid environment builds up condensation on its surface. No matter how much water accumulates, it's still uncompressible and it can bend the rod and/or damage the piston. Most of the time that much water doesn't accumulate, but it only takes few minutes to open the blow-down valves, crank the engine over a few revolutions, close the valves and off you go. Potentially bending a rod and rendering the machine unusable for weeks/possibly months is a pretty stupid thing to do considering it takes only 5 minutes to make yourself sure.
