Q

Operating a diesel engine under light loads and at low temperatures for an extended period can result in __________.

🔍 Key Concepts

• effects of light loading on diesel engine combustion • relationship between low operating temperature and fuel combustion quality • how fuel dilution actually affects lube oil viscosity

💭 Think About

• Ask yourself what happens to fuel burning efficiency when an engine runs cool and lightly loaded—does it burn more cleanly, or less cleanly? • Consider whether light loading and low temperatures are more likely to cause overheating, or the opposite problem inside the cylinders and cooling system. • Think about fuel getting into the lube oil: would that normally make the oil thicker or thinner?

✅ Before You Answer

• Check which option best matches incomplete combustion and poor burning conditions. • Eliminate any choices that describe overheating, since the question specifies low temperature operation. • Be sure you know whether fuel dilution increases or decreases viscosity before choosing that option.
