🔍 Key Concepts

• diesel engine combustion process and how it differs from gasoline engines • the role of compression in raising air temperature inside the cylinder • what fuel injectors actually do versus what causes ignition

💭 Think About

• Think about whether diesel engines normally use spark plugs or some other method to start combustion. • Ask yourself: do injectors ignite the fuel, or do they just deliver it into a very specific environment inside the cylinder? • Consider what happens to air inside a closed space when it is compressed rapidly—what effect does that have on temperature?

✅ Before You Answer

• Be clear on the difference between delivery of fuel and ignition of fuel. • Recall which engine type (gasoline vs. diesel) typically uses spark plugs. • Confirm what physical effect inside the cylinder actually reaches a temperature high enough to ignite the fuel.
