🔍 Key Concepts

• combustion in diesel engines and how air temperature affects ignition • effects of fuel temperature and viscosity on atomization and ignition quality • difference between systems that help the engine turn over (starting air, lube oil) vs. systems that help the fuel ignite

💭 Think About

• Which option directly improves how easily fuel ignites and burns in a cold cylinder? • Which options mainly affect mechanical motion or protection of parts, instead of combustion quality? • In cold conditions, what property of the fuel changes, and which choice best compensates for that change?

✅ Before You Answer

• Identify which choice directly changes fuel properties going into the cylinders • Consider which system most affects ignition quality at low temperatures, not just cranking speed • Eliminate any option that mainly serves lubrication or cooling, rather than helping the fuel burn
