Which outcome is caused by exceeding designed compression ratio limits within a gasoline engine cylinder?

💡 Explanation

When the compression ratio in a gasoline engine exceeds the designed limit, the air-fuel mixture can autoignite before the spark plug fires due to excessive pressure and temperature, causing detonation. Therefore detonation occurs, rather than valve float, lean misfire or pre-ignition, which each require separate mechanisms.
