Roughly it say:

The ASM is the sameas the AS but with improved Special Emergency power designed to run with C3 fuel and MW50

The same is for AM engine

Only the DB/DC engine colud use B4 or C3 fuel

DB/DC engine are the same with just a different setting, you can change this setting with simple screwdriver

The AM could use B-4 as well with maximum power (1.7ata), a G-14 MW 50 manual mentions that while C-3 is preferred as normal fuel, its possible to use B-4 in emergency with MW-50. It was more risky than using straight C-3 and MW 50 combo, since any failure in the MW system meant that the engine would immidiately start knocking and self destroy in short order. B-4 alone could not take the compression at 1.7 ata without detonation, while C-3 could. I have not seen a similar manual for the ASM but its a rather safe bet it worked the same, given the minimal difference (supercharger) between the AM and ASM.
