Q

A distorted spray pattern from a fuel injector can cause a diesel engine to have __________.

🔍 Key Concepts

• Fuel injector spray pattern and how it affects combustion in a diesel cylinder • Relationship between combustion quality and engine power output • What happens when fuel is not finely atomized or evenly distributed

💭 Think About

• Think about what a normal, well-atomized spray pattern does to the air-fuel mix inside the cylinder. How does that affect how completely the fuel burns? • If the spray is distorted (poor atomization, uneven distribution), what happens to combustion temperature and pressure, and how would that influence the work produced per power stroke? • Would a distorted spray pattern make the engine more efficient or less efficient at turning fuel into useful work?

✅ Before You Answer

• Check which option best matches the effect of poor combustion efficiency on engine performance. • Eliminate any choices that would require better combustion, not worse. • Consider whether fuel pressure in the injection system itself directly changes just because the spray pattern at the nozzle is distorted.
