Complex Engine Management / Oil on window ?

[Ivan Fooker]

Thx for all ya input.
As some of your correctly noticed, i am atm flying planes of the "good ones" .... means the B109E3.

Thus the mixture is atm no option,as i can run 0% or 100%.

Water Rad

For the actual pos. of the water-rad watch for the pins on the wings.

Could u or s.o. else plz take a screenshot to attachment plz...i ve no clue what you mean with that pin

Temperature

not only check temps, check oilpressure as well. That might be the thing causing you trouble.

Could some plz tell me where the max and minimum temperatures?

Oilpressure

not only check temps, check oilpressure as well

What is the average,minimum and maximum oilpressure?

Firstly, right next to the throttle, bump up the oil radiator to full (its a yellow knob)
Secondly, wind out the regular radiator (its on the right, you have to rotate the thingy)

If it still happens... well at least you've eliminated one option.

Hi Ivan, in the manual from the page 89 to the page 93 you will find some refferences about the 109.

Oil temperature should be kept between 30 to 75°C and could be as high as 95 during very short periods.

The water temp should be kept under 80°C, 105 can be maintened only for very short periods.

I fly almost exclusively the 109, I had troubles with the engine too, but now, just by checking the temps I don't face any problems.

The never exceed rpm is 3000, and the max takeoff power is 2450 rpm and 1.45 ATA (well 2400 or 2500 are fine), so you don't need to go to 3000 rpm to have more power. Don't forget to anticipate yours accelerations and decelerations to keep your rpm in the sweet powerband (2200 2500). Map keys for the oil rad and for the water rad (normally 5-6 7-. As said before you have an indicator on your left wing for the water rad position, and you can watch the position of the yelow lever on your left for the oil radiator.

In a dive the procedure is to cut the throttle an to set the prop pitch to 09:30.

I'm sorry but I don't know what are the limits for oil pressure but IIRC you have some white small triangles (marks), normally the needle should stay between them.

Here is a good page for some refferences about the 109 (E-4 but i think it's ok): http://www.shockwaveproductions.com/store/solo/bf109/

Have fun.

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.

[Derinahon]

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.

[Ivan Fooker]

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!
