🔍 Key Concepts

• diesel engine combustion characteristics at different temperatures • difference between white, blue, and black exhaust smoke colors • symptoms of poor atomization vs. overloading in diesel engines

💭 Think About

• Think about what happens to fuel in a cold cylinder that doesn’t fully support combustion yet. How would that look at the exhaust? • Which condition is most closely associated with unburned or partly burned fuel rather than oil burning or excessive load? • Consider which answer choice would most likely show up as a different smoke color (blue or black) instead of white.

✅ Before You Answer

• Match smoke color (white/blue/black) to typical diesel engine fault conditions • Consider engine temperature and fuel atomization when white smoke appears, especially at startup • Eliminate options that are more commonly associated with blue (oil) or black (overload/too much fuel) smoke
