K4 is easy mode vs. K4 is a symbol of courage

[bozon]

Hmmm.... I know I've read somewhere the P-51 used water injection. Have to find which book it is and mark that part as incorrect.


So would our D-25 be water-injected? Or would that be more in the D-30 range?

All our Jugs are water injected. Earlier D razorbacks did not come with the wanter injection from the factory, but all were retrofitted. There are rumors that some pilots removed the water injection system to save weight and instead simply over boosted their engines.

Mosquito NF.Mk XIX used nitrous oxide as well.  Kinda odd as it had the same low blown Merlin 25s as the Mk VI we have in AH.

What would be the advantage to a  water injection system? Less engine wear? Higher power compared to ramping up boost pressure?

That would probably vary from engine model to engine model.

[GScholz]

It was primarily an anti-knocking agent allowing for higher boost pressure without detonation. Through vaporization it cooled the compressed air in the supercharger making the air denser. A poor-mans intercooler.

That's why it needed it. The Supercharger couldn't provide enough air at higher alt. With a low-blower and NOS they could get good engine performance at all altitudes. My guess anyway...

This would be because of the poor fuel Germany used?

[GScholz]

Germany's aviation fuel was up there on a level with the western Allies. The radial 190s used C3, a synthetic fuel that was equal to 100/130 octane avgas. In late 1944 C3 would be close to 100/145 octane. The 109s flew on B4 which early in the was was about 90 octane, but later in the war was equal to 100/110 octane. The late-war DB605D (109G-10/K-4) could use both fuels and MW50. It produced 1,650 hp on B4 alone. 1,850 hp on C3 alone or B4+MW50. With C3 and MW50 it produced upwards of 2,000 hp. However, few 109 units got C3 fuel because the 190s needed it. In AH the 109K-4 has B4+MW50.

[Tank-Ace]

Oh, I thought B4 was lower octane fuel, and C3 was higher octane fuel that came around later.

[GScholz]

B4 could be produced from oil, so it was available in greater quantity. C3 was an expensive synthetic fuel produced from coal in large chemical factories.

[Tank-Ace]

Could a case be made for modeling a seperate 109K with C3 fuel and MW 50? Probably would be perked, since the K4 is close to that threshold as is, but would be very interesting to see.

Also, would be cool to see a Spit 14 modeled with 150 octane fuel. As for the rest, I'm not as enthisastic; even if its not likely, I just have this vision of AH being flooded with 150 octane P-51's, Mossies, and Spit 16s  .

[GScholz]

As long as it's perked it will keep the numbers down. I'd very much like to see a C3 fueled 109K and 100/150 or 115/145 fueled Merlin and Griffon engined birds.
