Diesel Engine Oil Pressure

Diesel Engine Oil Pressure

Diesel Engine Oil Pressure

(OP)
Hi

I am setting up a diesel Generator, so I want to know what a normal oil pressure reading in a hot summer would be ?

RE: Diesel Engine Oil Pressure

Check the manual and the documentation for your piece of equipment.

RE: Diesel Engine Oil Pressure

As noted, what the OEM says.

RE: Diesel Engine Oil Pressure

Depending on the type of engine, the viscosity may not influence the correct pressure reading. The installation and/or commissioning guide may have your answer. I woukd expect something in the neighborhood of 850kPa gage.

RE: Diesel Engine Oil Pressure

My 5.9 Cummins runs 65 psi at 2000 rpm and 30 at 900 rpm idle when fully warmed up. 195 deg F. It has 300k mile on it.

RE: Diesel Engine Oil Pressure

850kPa seems very high?

RE: Diesel Engine Oil Pressure

He didnt say what kind of engine, but the one I have in mind regulates at rougly that pressure. Emergency relief kicks in at about 1050.

RE: Diesel Engine Oil Pressure

okay, I made a mistake - the figure I gave was absolute, not gage pressure, and it is pre-filter. Post-filter would be 100kPA lower with a dirty filter.

RE: Diesel Engine Oil Pressure

The engine manufacturer will specify an acceptable range of oil pressure. As long as your high load/hot weather readings do not fall outside of this range you should be fine and your warranty should be valid.
