🔍 Key Concepts

• diesel combustion process and what creates complete vs incomplete burning • effect of fuel injection timing on exhaust color and smoke • how injection pressure and leaks change atomization of the fuel

💭 Think About

• Which of these choices would most likely lead to incomplete combustion of the fuel in the cylinder? • For each option, ask yourself: would this change tend to make the fuel burn cleaner with less smoke, or dirtier with more smoke? • Think about how injection that is too early vs too late affects how long the fuel has to mix with air before burning is complete.

✅ Before You Answer

• Identify which options would normally improve atomization and combustion (these are less likely to cause smoke). • Consider which condition would cause fuel to be injected when there is less time and/or less ideal conditions for it to burn completely. • Verify which factor (fuel property vs mechanical issue vs timing vs pressure) is most commonly linked with black or dark exhaust smoke in diesel engines.
