-With eight axial cylinders and oscillating plate, it was one of the last, if not the last test of this type of engine in Russia. It had a very low compression ratio, 3:1. The most visible advantage was its size and weight lower than any other equivalent.

-It seems that starting the engine was somewhat complicated.
