Oil dilution not working?


Reflected

Recommended Posts

Is it just me or the oil dilution is not working? I mean after startup I turn it on in the Spit and Mustang and it has a visible effect on the oil pressure after 5-10 seconds. In the Jug, absolutely zero. Is it not implemented yet or am I missing something? Maybe it worked less efficiently in real life? (close to not working at all?)

@Reflected I tried this out the other day, and dilution seems to be working. At least as of the current open beta (2.7.11.21408).

Are there any plans to fix this? Starting the jug takes a long time and is a major deterrent to flying it compared to other aircraft.

 

I think it is missing feature, not modeled yet. Plans for this and other stuff definitely a thing, question when, how many years.

It take about 13 minutes if you close every down to warm up the engine.

It depends i think 40C or 45C is minimum if you start from 20C for example, it takes less time if you start warming up from -10C yeah it will take time.

Regardless of the time and reason of use, if the oil is cooler than normal operating temperature range (flight manual says < 70 deg. C is OK, but fuel would probably evaporate pretty fast at 60 deg. too), it should gradually lower pressure with dilution switch on, and it will be most noticeable at cold start. Diluting before shutdown is used in cold weather conditions to prevent excessive pressure rise on next prop turnover and startup AFAIK, and in DCS we pretty much get new plane every time.

There are 2 cases of oil dilution procedures.

First one is oil dilution before engine shut down, to provide engine with safe oil pressure at engine start up at cold weather.

Second one is oil dilution to provide proper oil pressure at moderate power, like emergency take off.

Both oil dilution do not exclude each, so engine can be pre diluted before shut down and after start up pilot can dilute more to allow for emergency take off in winter time.

I just tested it, Oil dilution does not work in P-47 still.
