🔍 Key Concepts

• How a diesel governor works in basic terms • Relationship between fuel quantity and engine speed in a diesel • What parts actually change engine RPM versus what parts only influence performance indirectly

💭 Think About

• On a basic diesel with mechanical control, what must be increased or decreased to change how hard the engine "pushes" each power stroke? • Which component does the governor physically move or control to change that thing? • Which answer choices are more of a result of load/speed change, rather than something the governor directly adjusts?

✅ Before You Answer

• Identify which option is directly connected (mechanically or via linkage) to the governor in common marine diesels • Distinguish between cause of RPM change (what the governor acts on) and effect of RPM change (what changes because RPM changed) • Make sure the choice you pick is something the governor can realistically adjust continuously and precisely while the engine is running
