Ju87 and Bf109 engine idle speed

[GrahamHaddon]

Hi,

    Can anyone confirm or deny whether the engine idle speed on the Ju87 is to high? 800rpm seems to be the lowest it ever is. I have only read a quick excerpt from a manual for an earlier version but the warm up speed is only 600rpm so how can the idle temperature be 800rpm? The Ju87 is always trying to crawl along at idle. I also believe the Bf109 idles at the incorrect speed. Minimum in game appears to be 600rpm whereas in real life it is 400rpm and I believe very reluctant to run with the throttle set to idle unless warm which doesn't appear to be modelled. Can anyone tell me if I am right or wrong? Thanks.

I mean idle *speed not temperature

Please give the sources. The Jumo 211 went through rather krass development, higher compression, ratios etc. It does seem a little high, but considering the Location, maybe they're just set to high idle. The Oil has a hard time warming up in that climate, as well as the coolant. Same for the 601 and 605. The Ingame Version has a DB605A and DB601E, the 601 is a high powered version of the original version, higher compression and more boost. The 605 a larger bore 601.

Maybe you have early or prewar data, or for a different climate.

I must admit I hadn't considered the mechanics just setting a higher idle speed for colder climates. I know the starting instructions for both the DB601, 605 and Jumo 211 say that immediately after starting hold 600 rpm until the oil pressure gauge shows a reading. I can definitely find information on Bf109's having a set idle speed at 400rpm but this is not for a cold climate. But I can find no idle speed for the Jumo 211.

Maybe the developers have set higher than in real life idle speeds to avoid them cutting out at idle when cold to make things easier for us virtual pilots? Or perhaps not considered to be that important? It probably isn't I am just curious. Thanks.
