Complex Engine Management / Oil on window ?

[Derinahon]

Can anyone give similar advice for the Hurricane? Oil and water temps, plus optimum RPM and prop pitch? I'm just getting into CEM and I can't figure out how to keep the engine happy. At anything other than level flight I normally get black smoke and red flame pouring from the engine. I can adjust prop pitch and throttle to calm it, but I'm just guessing really!

With temperature effects my engine likely wouldn't last very long

I'm sorry I don't know so mutch about the hurricane, but you'll find infos from the page 85, go into C:\Program Files (x86)\il-2 sturmovik cliffs of dover\manual\

Remember that the hurricane is a gravity fed engine so negative G cut the fuel flow and make a rough engine, black smoke can be emitted when this happens.

Thanks, I've read that section of the manual but I was just after some advice regarding the black smoke scenario. I thought it was to do with mixture, but in the Hurricane you only have the lean setting for cruising so I'm not sure how to correct the black smoke/vibration when in combat for example.

Thx a lot for ya patience and explains!


Edit:
Your hints did the trick thx a lot.
One question remains to become a Pro Engineer....what is the the Oil/pressure clock supposed to do?
Means it is actually interesting only after taking shots, to control if any tubes got hit, and if i ve to get back home?

Let's have a quick look on oil pressure

If your engine is too hot, your oil pressure should drop (yes drop), if your engine is too cold your oil pressure should rise. So to influence your oil pressure you should manage the temp of the engine.

If the temperatures are normals a drop in the oil pressure mean probably a leak in the oil system (so probably a hit) or a lack of oil, but the sim hopefully don't simulate the need to replace oil before takeoff^^ or the oil pump is broken.
If the oil pressure rise (while temps are OK) then something is probably blocking a pipe in the system.

When the oil pressure is too low your engine is not correctly lubed (not sure of the term sorry) so wear increase and your engine may stop in a short time, when it's too high there is a risk of detonation and destruction of the oil system.

When the oil pressure drop sharply the best is to reduce throttle and fly with cruise settings or even shut down the engine because the temperature could rise very quickly until the engine catch fire.

On the BF i think the oil pressure gauge also indicate the fuel pressure (one of the needle is for oil the other for fuel pressure), as for oil pressure a drop indicate a leak.

So generally speaking a problem of oil or fuel pressure which can't be solved by managing the temperature of the engine is a really bad news and there is little to do but heading for home ASAP.

well the last couple of posts were actually pretty helpful... thanks!

[Ivan Fooker]

Thx jrg!
That really became a helpful thread to me!
That few lines to the manual and i am sure less people would suffer under complex motor management.
Once again thx!

We have a problem because the Hurricane (and Spitfire) mixture outputs are reversed to what they should be.
Engine Start:
Set mixture to RICH in cockpit.
Be aware that currently the mixture selection is reversed in the cockpit, RICH = WEAK and vice versa. On the DH prop Hurricane move the mixture lever all the way forward until it is fixed when it will be all the way back. On the Rotol Hurricane, closing the Throttle also closes the Mixture to RICH, which is what it should do on both Hurris. But remember RICH is in fact LEAN atm so with the Rotol move the throttle forward to just clear the START label then move the mixture up to just behind it, thats as RICH as you'll get without over-opening the throttle for startup. When running, handle the Rotol Hurri throttle opening carefully, moving the mixture lever forward behind the advancing throttle as much as engine running will allow. This should all go away once the problem has been fixed. See

Temps for takeoff:
Oil temp: min 15'C
Coolant temp: min 60'C (according to Pilots notes)

Open Radiator until you are in a position to manage the engine temp with it (70C - 90C, max 105C)

Takeoff prop is usually 3000 rpm, max boost. Climbout around 2600 with boost reduced around 4lbs. Combat in the region of 2600-2800. Cruise anywhere from 2000-2400, typically boost 0. These are from memory of the pilots notes but they should help.

I'm also getting that shaking syndrome in the 109. It's an intermittent but permanent shaking and sometimes it eases off and sometimes it's really bad.

The only way I can make it stop is running the engine at full throttle. The prop pitch doesn't seem to matter. I've tried all settings of prop pitch but the shaking remains.
Radiator and oil radiator are open; sometimes I close the engine radiator a little but nothing I do seems to stop the shaking, except again if I run the aircraft at full throttle. Temperatures are normal. It's wierd.

I also have an info box open that shows engine damage, but according to the game I have no engine damage. (?)

This is strange Rattlehead, I've noticed some vibrations too with the 109, it seems bounded by a bad engine management but I'm not sure. I say that because since I take care of my engine, the plane dosen't shake as mutch.
