DPF particulate filter / SCR removal in CATERPILLAR engines.

A non-invasive solution to remove the particulate filter without interfering with the electrical system of the CAT machine. The DPF particulate filter emulator and SCR is equipped with a wiring harness, which has original plugs. Installation on a plug & play basis.

Repair by removal of DPF and DPF with SCR (DEF).

Repairing the diesel particulate filter system involves connecting an emulator. Then remove the DPF filter by drilling it out or installing a regular muffler. The repair eliminates the failure of such elements of the exhaust system as:

DEF Pump
Inlet / Outlet NOx sensors
Catalyst / DPF temperature sensors
DPF Differential pressure sensor
DEF tank temperature and level sensor.

After removing the DPF (or DPF + SCR) the engine regains power. The regeneration of the particulate filter is not visible to the user. There is no need to refuel the diesel particulate filter when it is stationary. In machines equipped with an SCR system, there is no need to add AdBlue fluid (DEF).

Supported engine models: C3.3 / C3.4 / C3.8 / C4.4 / C7.1 / C9.3 / C13 / C15 / C18 / Perkins 1204F (CAT C4.4 with Perkins badge on it)

We also have solutions for other CATERPILLAR engine models. For more information, please visit our contact page.

CAT 972 - C9.3 ACERT

Presented below there are the CAT 972K and 972M loaders emulator installations. They differ only in the exhaust gas reduction system - the 972M model is additionally equipped with the AdBlue dosing system.

The CAT 972 has a Cat® C9.3 ACERT™ engine that meets Tier 4 Interim / Stage IIIB emission standards.

CAT D6T XL - C9.3 ACERT

Below you will find the removal of DPF filter and AdBlue SCR in the CATERPILLAR D6T XL equipped with the Cat® C9.3 ACERT™ engine.

CAT 336F - C9.3 ACERT

Below you will installation of DPF and AdBlue DEF SCR delete kit installation in the CATERPILLAR 336F Excavator equipped with the Cat® C9.3 ACERT™ engine.

CAT 980K - C13 ACERT

Below you will find the removal of DPF filter in the CATERPILLAR 980K wheel loader equipped with the Cat® C13 ACERT™ engine.

CAT M315D - C4.4 ACERT

Below you will find the removal of DPF filter and AdBlue SCR in the CATERPILLAR M315D wheel loader equipped with the Cat® C4.4 ACERT™ engine. We also have solutions for other Caterpillar machines with a C4.4 engine, for example CAT 432F backhoe loaders. The devices allows you to disable the diesel particulate filter - DPF and the SCR emission control system (AdBlue).
