Engine or Air Compressor

One crank turns x3 than the other. Connected with planetary gear to save room and make it robust. You are welcome to comment and say would work or not. As a internal combustion engine design I'm curious what the torque and power output will be. The pistons are with different diameters and travel patterns. Thank you for looking. This is concept idea that maybe is already out there. I never found anything in google.
