Maximum ISB Engine Angles?

[rbattelle]

Does anyone know what the maximum angles, in pitch and yaw, the ISB in the Dodge can be run at without getting into problems with the oil system? I emailed Cummins and they said ask Dodge, because the oil pan design is a bit different than the usual ISB.

"pitch and yaw"

The ISB is a little heavy for use in aircraft.....

For now... just wait till I start designing them (airplanes, not the Cummins)... there WILL be a Cummins in an airplane someday... mark my word... .

ohhh about to the point

you roll it over on the roof

Oo. Oo. Oo.

Can't seem to find it but there was an issue with the ascent angle about 17%(or degrees) or something that would cause crankcase oil to pump out the vent tube.

I found some info on the marine 6BTA.

I don't know if the numbers would be the same on the ISB because the oil pans are probably different. Compare the oil capacities

I finally got the opportunity to examine the cutaway common rail engine when it was displayed at NAIAS this year. I noticed that the oil pickup tube is all the way at the back of the engine, runs along most of the width of the oil pan, about 1 inch forward of the rear pan wall. Maximum positive (nose up) and side (roll) angles should be very high, but maximum negative angle (nose down) is probably somewhat low. I'll have to take some measurements of the pan to work out what the real maximums would be...
