Which outcome arises when a turbocharged diesel engine experiences significant turbocharger lag during rapid acceleration?

💡 Explanation

Reduced air mass flow causes turbocharger lag because the turbine requires exhaust gas velocity to operate; therefore, combustion is delayed leading to decreased torque in low RPMs, rather than immediate boost or pre-ignition under normal conditions.
