What Might Be Causing My Yak-1 Engine to Stop Suddenly?

[Bearfoot]

It's happened a couple of times to me so far, only in MP (WOL).

 

(1) It is NOT over-running the engine: both times I was cruising back to base, so I had both throttle and RPM down to 50-60% for a while, both radiators fully open.

(2) It is NOT the temperatures: both water/coolant and oil temps below critical threshold.

(3) It is NOT the gas: both wing tanks at > 80%.

 

Just cruising along, no worries, and then engine just stops.

 

Any ideas?

Kiss it gently and remind it how much you love it before you tuck it in to bed.

 

What were you running for mix? I notice you didn't specify.

Run too low mixture, and the engine will die at some point.

 

There is also the possibility, that you over-cooled your engine. If you ran it at low throttle, low rpm and had both radiators fully open, it's perfectly possible that you cooled your engine enough, that it broke down from over-cooling. You have to watch the temperature gauges. It is not enough to simply open the radiators and assume, that everything is going to be fine.

Where you flying inverted for some time? If yes that is the cause, this simulation, simulate the fact that most of WW2 planes cannot fly for more than 30 seconds inverted because they do not have oil pumps to lubricate their engines in an inverted position. RTFM. Even modern aircrafts like the P-38 had this warning in their manuals.

i'm with Finkeren on this, because as soon as he throttled down his engine stopped, which means his engine would have gotten too cold.

 

when i land i always close my radiators.

Ah, yes --- mixture and over-cooling.

 

I am pretty certain that I had the mixture at full rich, though. But I could be mistaken about that, and, if so, it would explain it, especially since on both occasions I was at really low level.

 

Overcooling: this, too, could be the case, though I am not certain now as I did not register the temperature exactly but just noted it was well below the max values.

 

Thanks to you both for the insight! Now that I am aware of these, I will know what to look out for the next time!

Nope, not flying inverted.

I've thrown the Yak into some weird settings and it's never actually quit on me.

 

I'll be interested to know what it is.

 

Usually overcooling will be accompanied by the snowflake HUD icon, so you should have noticed that unless you fly with HUD off.

Its always good to make tracks and review them when stuff like this happens.

I fly with HUD off!

True. But AFAIK, you have to decide to start recording the track beforehand, right (not like in, e.g., DCS, where you can elect to save the track after the flight)?

I had my Yak-1 engine die on me this morning flying in the Stalingrad Part 2 campaign upon landing on the snow covered runway. And this was on Normal realism with automated engine management.

 

Those winters in Stalingrad can be brutal on engines.

I always do, no matter what. If there are important tracks I will rename them after the flight. I usually delete my unimportant records every 2 months or so to free up some space on my SSD.

You can use shadowplay to capture it without the need of recording long segments in hopes of catching it

I would not recommend that though. The ingame tracks are smaller in size and enable you to go to all kinds of different views in replay.
