This has happend to me a couple of times on-line and off. I am flying along, usually at 15K feet plus or minus, then all of a sudden my plane starts shaking like the engine is out of balance. There are no indications in the display box, temps are good, mixtrue dosen't change it. It will not clear up so I eventually land and start a new mission. This has happend in both the Spit Ia and the 109 E3. CEM is on. I have not been attacked.

What is happening?

Like I said, I tried that. I tried every adjustment I could. It just keeps shaking.

Take care of the Limiting Operational Condition of the planes you fly.

very usefull informations about this:

I think if you break your engine and it starts to shake, then there is nothing you can do to repair it: the engine is already broken. So if it start to shake it wont stop anymore even if you set properly mixture or radiators.
You need to handle it well before it start to shake.

Open rads. Before you take off open water rad 1 full turn. Open oil rad half way and you're set.

If you pull the throttle all the way back the shaking will stop! This means you overheated your engine..but didn't do enough damage to cause oil to leak.

For the first time last night I flew through a large cloud in CoD. The windows froze up almost completely and the engine strted to run rough. After the windows had a chance to clear a bit the engine ran smooth again.

Could it have been induction icing being modeled? Never experienced it before!

Cheers!

I can confirm that flying through clouds causes the engine to shake. I assume the engine gets moisture along with the air.

Do it again but this time slide open the window and fly through cloud. See what happens then and report back to every one.

I alway monitor the temps, etc. That's why I can't understand why the shaking starts. Usually, I get a message in red when something happens to the engine, but I'm not getting that. It is also strange to me that it happens in such totally different airplanes.

Yes this happens to everyone..the shaking isn't enough damage for a red warning in the chat menu. You are running too hot, or too high RPM.

There's nothing else to say about this..you are killing your engine...when you reduce throttle all the way the shaking will stop..this is how you know you jacked up the engine and its not a bug! Try it

I didn't think it was a bug, I just wanted to know what I may have done wrong. Thanks for all the responses.

I think there are 3 main things you have to consider to avoid that: mixture setting, water radiator and oil radiator. In 109 E4, for example, ( automatic prop pitch ) with both radiators open is enough to avoid shaken.
Check also your prop pitch if manual. It can cause you to over rpm the engine when diving at high speed.

If your engine shakes it some thing you've done or not. High revs and/or temp. Try getting used to lower your revs when cruising and always keep a close eye on temps. Cut the throttle befor diving if you don't have time to set the prop, it only takes seconds to blow the engine in a dive.
