Q

If a diesel engine starts firing, but is unable to come up to normal speed, the cause may be __________.

🔍 Key Concepts

• Fuel-air ratio and how it affects engine speed • Role of the governor in maintaining diesel engine RPM • Effect of exhaust system restrictions on engine performance

💭 Think About

• Think about which problems would let the engine start and fire, but prevent it from reaching full speed rather than stopping it completely • Ask yourself: which option(s) directly limit how much power the engine can actually produce under load? • Consider whether more than one of these conditions could realistically cause the same symptom (slow to reach normal RPM)

✅ Before You Answer

• Verify which components control fuel quantity and engine speed once the engine is already running • Check how exhaust back pressure affects scavenging and cylinder filling in a diesel engine • Consider whether the symptom described could reasonably be caused by more than one of the listed issues
