FW-190A8 Engine does not stop properly

[spitfirejoe]

I hope this is no double post, I searched and did not find anything so far.

 

When I want to stop the engine on the Fw-190A8 it does not want to stop for a very looooong time, not normal. I hope for a bug fix.

 

Thank you

The A8 "engine does not stop" bug is still present!

The engine is switched off and it continues to run for ages.

[FlyingH]

"for ages" meaning? One minute, one hour?

[LukeFF]

I'm not seeing any issue here at all. The engine stops just fine.

[spitfirejoe]

hello "LukeFF" 

really? If you are on the ground not moving and pressing key E does it stop just normal? On my PC it doesn't, the Engine continues to run minimum 90 seconds until it stops.

Because it´s only the A8 on my PC I thought about a bug, which I just wanted to report, nothing more.

It's not your pc.  The A8 does engine does run on after its switched off on landing.

 

  I always assumed it was because I'd given the engine a thrashing and this was a pre-ignition effect.

Hello DDArtur, well the strange behaviour is that the engine wants to stop like normal and then it ignites and starts again and that is happening many many times like a faulty loop untill after a long time it suddenly stops. For me it just does not makes sense  that LukeFF does not have that?!

I understand what you mean and have experienced it myself with the FW190.  It does not happen all the time but does seem to happen after the engine has been run at high power settings for an extended time and then landed shortly afterwards.

 

I do not know whether this is a bug or some sort of pre-ignition condition.  I'm not sure whether that condition has been modelled or not.

 

My point is it is not a problem with your own copy of the game or your PC.   I will see if I can replicate later today.

OK thanks DD_Arthur for explaining, now I understand what you mean. I will test when I am back home, now I am in China for a Business trip.

Would love to get some feedback by  a Dev or somebody who could clarify if this is on purpose or not, even it is not a gamechanger or annyoing or something, I am just curious.

Thanks and have a great day.

In that video the throttle is being pumped as the engine is shutting down.  Are you doing that or is the automatic shut down sequence doing that?  Fuel has already been shut off, but maybe the pumping of the throttle to full and back is injecting residual fuel into the engine.

Yeah, I'm moving the throttle but the fuel cut off valve is down and more importantly,  magnetoes are off.

I can understand residual fuel being present but what is the source of ignition?  Before landing I'd fairly thrashed the engine so is this a bug or is some sort of pre-ignition modelled?

Seems a bit contrived to make a point by pumping the throttle. It's the first thing I noticed as well. The fuel cutoff stops the fuel at or near the tank. There is still fuel in the lines and pumping the throttle would drive the residue forward. I've had the motor run on for a several seconds after full shutdown but nothing that would alarm me. I've had the 109 E do that as well.

 

Even if it is a bug, it's a pretty minor one. If you've ever driven a pre-70's car, you know shutting down doesn't always mean shutting down. Mountains out of mole hills, this one.

My only point is to demonstrate that it does happen.  Mountain out of a molehill?  No, merely curious as to whether this is a bug or - as I initially thought - modelling of a pre-ignition condition by design; which would be pretty cool.

 

Obviously there is residue fuel mixture present after the cut off valve has been used and the pumps switched off - though I'm not too sure how much impact fiddling with the throttle in a fuel injected system would have - but if the magnetos are off what is the ignition source?  

 

Hotspots within the combustion chamber?  Seems doubtful as generally LW engines were big, low compression designs to run on low(er) octane fuel.  I would have thought that would have been more efficient at preventing fouling compared with higher boost, higher octane allied designs. 

 

 

 

 

Or it could be merely a minor bug.........

This has always been going on with the A-8, since it's release. It backfires like 10X after you land and shut the engine down. It does this even when you land and let the engine idle for a minute or two.

 

A couple of backfires after flogging the engine on a mission might be a cool effect, but this is too much.

 

The (much) bigger issue with the A8 is the unrealistic overheat at 1.35 and 1.42 ata, the incorrect cooling flap settings - all of which severely restrict the aircraft's performance.

Thank you for your post....I agree 100%. I hope these bugs will get fixed.
