What function of the fuel system breaks up the fuel into smaller particles?

• A. Vaporization
• B. Filtration
• C. Atomization
• D. Combustion

Answer: (C)

Atomization is the process that breaks fuel into a fine spray of tiny droplets. In fuel systems, injector nozzles or high-pressure jets disrupt liquid fuel so it forms small droplets, increasing surface area and promoting rapid evaporation and better mixing with air for efficient ignition. Filtration only removes contaminants, not break the fuel into particles. Vaporization is turning liquid fuel into vapor, which can happen after atomization, but the act of creating the small droplets itself is atomization. Combustion is the burning of the fuel, not its breakup.
