← ScienceWhich consequence results when exceeding compression ratio limits in engines?
A)Detonation reduces power output✓
B)Increased lubricating oil viscosity
C)Premature exhaust valve failure
D)Higher thermal convection losses
💡 Explanation
Exceeding compression ratio limits causes uncontrolled auto-ignition: detonation. The rapid pressure rise damages components, because fuel ignites before the spark, hindering controlled combustion; therefore, detonation reduces power, rather than causing lubrication or valve failure.
