Initial model of different hydrocarbon gas ratio systems: (a) CH4/C2H6/C3H8 = 100/0/0; (b) 90/5/5; (c) 80/10/10; (d) 70/15/15; (e) 60/20/20; (f) 50/25/25. The blue dot refers to the COM of the piston, and the red dot refers to the reference point. In order to distinguish, re-color the methane atoms. Atom color codes: violet, C in hydrocarbon gas; purple, H in hydrocarbon gas.
