Question

what is the relation between compression ratio and the efficiency of the Otto cycle ?​

Answer 1

~$\small \blue {\sf{an\ ideal \thermodynamic \</p><p>combustion\ cycle\, as\follows: \a \compression \at \</p><p>constant\ entropy\; a\ constant-volume \heat transfer \</p><p>to the system; \an \expansion\ at constant\ entropy; \</p><p>and\ a \constant-volume\ heat \transfer\ from \ the \</p><p>system. }}$
