Emulators for U.S. Trucks (SCR / DPF / DEF)

Looking for reliable SCR / DPF / DEF emulators for U.S. trucks? Our plug-and-play emulators are designed specifically for American heavy-duty vehicles such as Freightliner, Kenworth, Peterbilt, International, and others equipped with Detroit Diesel, Cummins, PACCAR, or Navistar engines.

These units help bypass faulty aftertreatment systems and eliminate issues caused by failed DPF, DEF, or SCR components. Ideal for off-road, export, or special-use applications where reliability and uptime matter most.

What Are SCR / DPF / DEF Emulators?
SCR (Selective Catalytic Reduction), DPF (Diesel Particulate Filter), and DEF (Diesel Exhaust Fluid) systems are common in modern diesel trucks. While essential for emissions compliance, they often lead to expensive repairs, downtime, and error codes when components fail.

Emulators are electronic devices that simulate the signals and functions of the aftertreatment system. When installed correctly, they:

Disable the DEF dosing system

Eliminate DPF regeneration cycles

Bypass faulty NOx and temperature sensors

Prevent derates and limp mode

⚠️ Important: Emulators are intended for off-road or export use only. Not legal for use on public roads in emissions-regulated regions.
