Q

The efficient burning of fuel in a diesel engine is dependent upon the __________.

🔍 Key Concepts

• diesel combustion process in the cylinder (what is needed for complete burning) • role of temperature and pressure at the end of the compression stroke • importance of fuel spray quality (atomization and penetration) in mixing with air

💭 Think About

• Think about what conditions must exist in the cylinder for the fuel to ignite and burn efficiently once it is injected. • Ask yourself: does only one factor control efficient burning, or do several work together in the combustion chamber? • Consider how the fuel must be prepared and delivered (sprayed) and what the air conditions must be like for good mixing and complete combustion.

✅ Before You Answer

• For each option, ask: Does this factor directly affect how well the fuel mixes with air and burns? • Consider whether temperature of compression alone would be enough for efficient burning without proper fuel spray. • Consider whether atomization or penetration alone would work if compression temperature and pressure were too low. • Before choosing, check if more than one of these factors is clearly essential to proper diesel combustion.
