Is type 100 12v? 4 colour's each color looks like a voltage value since type 100 have the light blue color and the light blue is 12V
12V is the cylinder count, the blue is literally just a random colour element
If both of you are talking about this slide. The 4 colors represent 4 development stages that lead to the power pack of type 100. (Key background pre-study -> key background pre-study deep dive -> deep dive study and demo -> type development). No offence, but you two seem don't read Chinese?
type 100 is likely a V10 engine.
See the lower left image labled 88KW/L HPD110 柴油机? It has 5 cylinder heads, V shape gives you 10 cylinders, so it is a V10.
Finally, although 6V, 8V,10V, 12V are highly likely designation of engine arrangements, they are put aside PPLT. So the interpretation should be combined. I can't find any Pinying initials of Chinese words that may be PPLT. But I guess that we are looking at a powerpack family that includes various engines of different rating in conjuntion with direct or electric drivetrain. If this interpretation is right, there could be a larger powerpack than Type-100, e.g. 12V electric drive.
