Question 1 of 27070

If it becomes necessary to clean the spray holes in a diesel engine fuel injector, you should use a suitable size piano wire and __________.

🔍 Key Concepts

• Injector spray holes are very small and easily damaged by improper cleaning methods • Diesel fuel systems are designed to work with materials and cleaners that will not leave residues or react dangerously with fuel • Think about what type of cleaner is commonly used in fuel-system maintenance to dissolve carbon without harming precision parts

💭 Think About

• Which option would best dissolve carbon deposits while being compatible with diesel fuel system components? • Which substances in the choices might leave a residue, cause corrosion, or create a fire or explosion risk when used on fuel-system parts? • What type of product is normally specified by manufacturers for cleaning internal fuel components?

✅ Before You Answer

• Eliminate any option that is obviously unsafe around fuel or could create a fire hazard (flammability concern) • Eliminate options likely to leave films or residues that might affect spray pattern or clog holes (no residue requirement) • Focus on the choice that is specifically intended to break down carbon-type deposits on metal parts without attacking the metal itself (material compatibility)
