Q

If a few injector spray holes become plugged, the result could be __________.

🔍 Key Concepts

• diesel fuel injector operation and how spray pattern affects combustion • what happens inside a cylinder when fuel is not finely atomized • relationship between uneven fuel delivery and engine symptoms (noise, speed changes, smoke)

💭 Think About

• Think about what a normal injector spray pattern should look like and how it helps fuel burn completely. What changes when some holes are blocked? • If one or more cylinders are getting a poor spray pattern, how might that affect engine smoothness, combustion quality, and the sounds the engine makes under load? • Which symptoms listed could reasonably come from uneven or incomplete combustion in one or more cylinders?

✅ Before You Answer

• Be sure you understand that plugged injector holes = less fuel and poorer atomization in that injector’s cylinder(s). • Ask yourself if incomplete or uneven combustion can cause speed fluctuations, abnormal knocking, and visible signs of poor burning—or only some of these. • Before choosing, verify whether each option could logically result from improper injector spray pattern, not from unrelated systems like governor linkage or air intake.
