All greetings! Very long ago I here was not. There were on that reasons. I after all again am not simple so. There is a business. Search at a forum that something has not given... And the following interests me. Whether there was system MW-50 on serial fighters FW-190A4? As far as I know on A4 possibility for installation MW-50 has been provided. And in general changes have been made to a design (in comparison with A2/3), as that: landing places on frames, the union for connection of highways, a hole in the panel of devices for giving cranes etc. But serially the system was not established. Some cars have been equipped and there passed tests in Рехлине (Rehlin ?), then "army" in JG2 and 26. It has been by results decided not to put, since the gain in speed was not big, but weight (and system cost) big. Besides, then have started to test gasoline injection in an air inlet, and it has appeared much more effectively, and besides is easier and cheaper (while the Romanian oil from which was readily available did gasoline C3). In the end of war when with the natural it became high октановым gasoline badly, began to come back again to spirit to systems. On А8 and А9 sometimes put and метанол and ethanol. Nevertheless, gasoline injection in an air inlet was the basic system always. "C3 айншпритцунг (I do not know as on English it to translate )". Therefore me very much interests: First, whether was MW-50 on FW-190A4. Secondly, than to explain here it: Post War Flight Test Evaluation of 190A4 especially http://www.wwiiaircraftperformance.org/fw190/ptr-1107.pdf Especially me comparison with the American planes interests. In the same place it is spoken. That included something. That increased capacity of the motor, but is not spoken about that. That this for system was. It is gasoline injection in an air inlet or not?
