Engine limits for cruise setting (auto-lean mixture)

[CSW_Tommy544]

Hello,

 

would it be possible to update the in-game Specification tab for aircraft that have the possibility to set their mixture controls to auto-lean with engine limits when running such mixture setting? I know that the A-20 has this information already available in the Specification tab, however, all of the other planes seem to be missing it. I don't believe that you can detect engine knock in this game, which would signal that you need to change your settings, so memorizing these values is probably the only way. If this information is available somewhere, please let me know. I would also be OK with just having it separate from the game, though having it in the game would be much more convenient for everyone.

 

I am asking for it especially because it seems like running the engine in max continuous setting with mixture set to auto-lean will eventually damage the engine (which is correct I guess), but we don't know the exact safe setting. I was able to, for example, find some values for RPM and Manifold pressure for auto-lean cruise setting for a P-47 in its DCS manual, but I don't know if those values necessarily match with how the engine is modeled in IL-2.

 

Thanks

Economic cruise settings for all planes would be very welcome indeed ?

What plane and what RPM & Manifold Pressure settings were you using when you saw this damage?

I think the only damage you get from running in auto-lean would be purely temperature related. AFAIK pre-detonation from too lean of mixture is not modelled.

I haven't tested it myself, but several people from my squad were getting their engines damaged while running P-47 on max continuous setting while on auto-lean mixture. I heard that this damage appeared after roughly 20 minutes of flight. If you think that all planes that don't have engine settings for auto-lean mixture written in their Specifications should be fine running max continuous on auto-lean then I can test it as well, just to be sure.

Alright, maybe this is a non issue. I flew an hour long flight with P-47 running auto-lean mixture at max continuous engine setting while making sure that all temperatures were within limits and there was no damage to the engine. I will be trying this with other planes as well, but it might be possible that the game allows auto-lean mixture on max continuous setting if you can keep the temperatures in check.

What i used is:

2550RPM @ 32 “ inHg for auto lean

If i remember correctly i got it from a P47 flight manual.
