Pe-2 engine management question

[grokery]

Hello, new player here, love the game so far, having a lot of fun.

 

I have a question about engine management in the Pe-2 (87 series). I have read Chucks excellent guide and unless I'm missing something, cruise settings for the PE-2 are listed as 2200 RPM and 1020mm Hg Manifold pressure.

 

Now my question is, am I supposed to cruise with the throttle set to max and just reduce RPMs?

 

With the throttle fully open the manifold pressure is around 105(x10). I can drop the engine RPM to 2200RPM, but is the throttle supposed to be pegged at 100%? This is at 1k feet with no ordnance, but full fuel. When I set RPM to 2200, max manifold pressure drops to 900, airspeed is 350km/h.

 

To confuse me a bit more, the briefing spec page says that nominal engine operation is at 2700 RPM and 1050 MP. Am I missing something or can you just run these engines flat out indefinitely?

 

Thanks in advance for the help!

The 87 can fly with all maxed out. Once level you should reduce rpm getting the props to eat more air. Settings for engines works different on different altitude. 
keep radiators fully open under climb.

For booth pe-2: I fly it with 40% fuel, rpm max, trottle max, radiator(s) max or little bit lower. The only thing to remmember is to reduce mixture after take off. There are 3 zones of mixture: rich, medium and lean. I use medium but next to lean. After that I do not touch engine management any more.

PS: do not forget bomb doors button.

Thank you for the replies! I had been leaving the mixture at rich (100%) I'll try adjusting that. Good to know you can run everything flat out.

The engines will overheat eventually in combat running flat out. Watch your temperature gauges--the oil and coolant should be in a range, too hot and your engine overheats, and too cold and you lose some power. Leaning your mixture out conserves fuel, but is altitude dependent, too; too rich at high altitudes causes smoke trails and hurts engine efficiency.

Ah! It's actually really easy to see when when fuel mixture is too rich, just look outside for smoke trails, thank you cardboard!

If you ever fly the Pe-2 series 35 (in Battle of Moscow), note the following:

• You can control mixture by referencing the two gauges at the top right with the alpha symbol on them. Adjust your mixture so that the gauges read 0.9. Less than 0.9 is richer and greater than 0.9 is leaner.
• There is a fuel gauge for the center tank just below the gauges shown here. You can see the center tank gauge from the cockpit gunner's position.
