🔍 Key Concepts

• diesel engine governor function and purpose • difference between starting air system vs. running (fuel/governing) system • how air leaks or restrictions usually affect engine speed and power

💭 Think About

• Think about which component is responsible for automatically holding engine speed steady when load or conditions change, even if the control setting stays the same. • Ask yourself: if the engine speeds up without the operator moving the throttle/bridge control, what system has most direct control over fuel to the engine? • Consider whether air problems (leaks or blockages) are more likely to cause loss of power and speed drop, or a sudden increase in speed.

✅ Before You Answer

• Identify which choice directly controls fuel rack/fuel quantity as load and speed change. • Decide whether a starting air problem would affect an engine that is already running at speed. • Consider whether a clogged intercooler or air leak would more likely cause under-speed / power loss instead of over-speed.
