    • Common in older CAT skid steers, compactors, and telehandlers.
    • Fuel system: Mechanical injection.
  • C4.4 ACERT Tier 3 (Electronic)
    • Found in mid-generation CAT excavators, loaders, and dozers.
    • Equipped with electronic control module (ECM), improved emissions compliance.
  • C4.4 ACERT Tier 4 Final (Advanced Electronic)
    • Latest generation with DOC/DPF/SCR aftertreatment.
    • Fully electronic, high-pressure fuel system, meets Tier 4 Final / Stage IV emissions

 

?? Tip for customers: Always provide your engine serial number (ESN) before ordering to ensure compatibility. Even within the C4.4 family, flywheel housing, turbo, and fuel system may differ.
