Yes, and if i am not mistaken, it's by Denso Japan, same brand used by the D-4D Toyota. I hope Mitsu Di-D wouldn't suffer the same fate.

The problem with the japs is that their technology (and often design) was mostly copied from the Europeans (often from the Germans), often without consent/license so it's mostly guesswork from the start. That's how it used to be, at least for the past decades. I'm not sure about the present.
