Only one part of the multi-cylinder H engine can be seen on my animation. As you can see from the history, it can be 24 cylinders .. the order of ignition can also be seen in wikipedia .. If we properly think, the customs of the main cylinder system from Felix Roller, may not have ANY ONE SCREW to twisting .. :wave:
