Answer:

incorrect exhaust valve timing

Early opening of the exhaust valve leads to:

  • Higher exhaust temperature of the unit due to opening the valve while fuel still burns
  • Fouling of the exhaust gas system by carbon deposits from partially burnt fuel
  • Reduction of engine power and efficiency

Late opening causes:

  • Reduced time of scavenging and hence, its efficiency
  • Reduced turbocharger efficiency
