🔍 Key Concepts

• Fuel atomization – how finely the fuel is broken into small droplets as it leaves the injector nozzle • Penetration – how far the fuel spray travels into the compressed air in the cylinder • Relationship between droplet size, spray cone shape, and air–fuel mixing in a diesel cylinder

💭 Think About

• Think about what happens when fuel is broken into very fine droplets versus large droplets – which travels farther into the air charge? • How does a finer spray affect the contact area between fuel and air, and what does that do to the spray’s ability to ‘push’ deeply into the cylinder? • Consider how injection pressure and nozzle design change both atomization and the distance the spray can reach.

✅ Before You Answer

• Be clear on the difference between atomization (droplet size) and penetration (spray distance) – they are not the same thing. • Visualize a spray nozzle: as you increase fineness of the spray, what happens to spray momentum and thus to how far it can penetrate? • Eliminate any choice that says atomization and penetration are identical processes or completely unrelated; focus on how one typically affects the other.

Question 1 of 20

Which of the following statements concerning fuel atomization in a diesel engine cylinder is correct?

The greater the atomization, the greater the penetration.

The greater the atomization, the lesser the penetration.

The degree of atomization has nothing to do with the degree of penetration.

Atomization and penetration are one and the same.
