Which outcome happens when the compression ratio exceeds design limits in supercharged gasoline engines?

A)Increased brake specific fuel consumption
B)Detonation spontaneously ignites the mixture
C)Methane radiative forcing rate increases
D)Volumetric efficiency proportionally increases

💡 Explanation

Exceeding compression ratio limits will likely lead to detonation because adiabatic compression increases temperature past the fuel's auto-ignition point, causing premature combustion. Therefore, detonation occurs rather than controlled burning, because compression goes beyond designed tolerances.
