Which outcome occurs when wastegate failures block boost pressure regulation?

💡 Explanation

Increased boost pressure, without wastegate regulation, causes extreme cylinder pressures; autoignition occurs because uncontrolled compression increases temperature beyond the fuels flash point. Therefore, engine knock increases; rather than improving as may happen under normal operations controlled by boost levels.
