Question 1 of 27070

If a diesel engine were running at 20% overload with a smoky exhaust, you should __________.

🔍 Key Concepts

• Diesel engine overload effects on temperature and stress • Relationship between sustained high load and internal component damage • Proper way to reduce load and temperature without thermal shock

💭 Think About

• What happens inside a diesel engine (pistons, valves, turbocharger, exhaust passages) when it is run at 20% overload with visible smoke? • Would an abrupt change (sudden stop or rapid temperature change) be less safe than a controlled change in operating conditions? • Which option actually reduces the mechanical and thermal stress on the engine rather than making it worse?

✅ Before You Answer

• Identify which choice reduces engine load in a controlled way. • Check which actions could cause thermal shock or uneven temperatures in engine parts. • Eliminate any option that does not directly address overload and high exhaust temperature (i.e., does not actually reduce the stress causing the smoke).
