🔍 Key Concepts

• How fuel oil viscosity affects atomization at the fuel nozzle and mixing with air • What conditions generally improve combustion in a diesel (compression, air supply, scavenging) • Typical problems seen when blended or heavy fuel oil is not properly heated or treated

💭 Think About

• Think about which factor would make it harder for the injector to spray a fine mist of fuel into the cylinder. • Ask yourself which of these choices would normally HELP combustion rather than hurt it. • Consider what happens to spray pattern, penetration, and ignition delay when fuel is too thick or too thin.

✅ Before You Answer

• Identify which option directly changes spray quality/atomization at the nozzle. • Identify which options are normally associated with better air supply and combustion, not worse. • Recall that blended or heavy fuels often require heating to reduce viscosity before injection.
