Which of the listed conditions can cause a diesel engine to use too much lube oil?

Question 1 of 27070

Which of the listed conditions can cause a diesel engine to use too much lube oil?

🔍 Key Concepts

• How piston rings help seal the combustion space and control oil usage • The effect of oil viscosity and temperature on oil flow and consumption • Common mechanical causes of increased lube oil consumption in diesel engines

💭 Think About

• Which option describes a condition that allows more oil than normal to enter the combustion space and be burned? • For each choice, ask: does this mainly restrict oil flow, or does it create a path for oil to be lost/consumed? • Think about what actually wears out in an engine over time that directly affects lube oil control on the cylinder walls.

✅ Before You Answer

• Identify which condition would most likely let lube oil pass into the combustion chamber and be burned as fuel • Check which options would tend to DECREASE flow or consumption rather than increase it (e.g., restriction vs. leakage). • Focus on typical signs of engine wear that lead to higher lube oil consumption in medium- and high-speed diesel engines.
