🔍 Key Concepts

• Governor and fuel control linkage function in maintaining constant engine speed • Effect of load changes on a properly governed diesel generator • How fuel properties and injection pressure typically affect combustion versus speed stability

💭 Think About

• Which component actually adjusts fuel rack position to keep the generator at a constant speed when load changes? • If the governor sends the correct signal but the rack or linkage cannot move freely, what will the engine speed look like? Smooth or hunting/irregular? • Do changes in fuel viscosity or injection pressure normally cause a steady speed change, or a mechanical "hunting"/surging of RPM?

✅ Before You Answer

• Identify which option involves a mechanical restriction in the speed‑controlling system. • Decide which options mainly affect power/combustion quality rather than directly causing speed to fluctuate up and down. • Ask: in normal operation, does high load alone cause irregular speed, or does the governor compensate to keep RPM steady?
