🔍 Key Concepts

• how a properly operating fuel injector nozzle should spray fuel into the cylinder • what happens when fuel drips or dribbles instead of being finely atomized • consequences of unburned or poorly burned fuel on injector tips and combustion chamber surfaces

💭 Think About

• Think about whether dripping fuel occurs at the correct time in the cycle or slightly late, and how that affects combustion quality. • Ask yourself: does dripping fuel tend to improve or worsen atomization and mixing with air? What does that usually do to combustion and deposits? • Consider what long‑term effect repeated poor spray/combustion near the nozzle holes might have on those small passages.

✅ Before You Answer

• Compare the effects of good atomization vs poor atomization on combustion completeness and temperatures. • Consider whether dripping fuel is more likely to clean the nozzle or to leave carbon deposits somewhere. • Eliminate any options that would logically require better timing or better atomization of fuel, since dripping is a sign of a fault.
