← ScienceWhich 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.
