Diesel Particulate Filter (DPF) - Tier 4

Whayne Supply Company has installed the Diesel Particulate Filter (DPF) on nine customer owned earthmoving machines

A diesel particulate filter is used to reduce the exhaust particulate matter emitted by an engine. By definition, the DPF accumulates the particulate matter (soot) and oxidizes it with a passive, active, or combined strategy.

Diesel engines are sensitive to backpressure created by any restriction in the exhaust flow. When a DPF is used, the backpressure varies depending on the soot loading in the filter. The filter will fill up with soot and ash over time and periodically require cleaning. As a result, a backpressure monitor is used to inform the vehicle operator that the filter needs cleaning.

Monitoring exhaust backpressure is also a useful way to identify the condition of an engine. Increased soot levels from the engine will cause the filter to load faster. Identifying this trend allows the service technician to correct engine problems before they become severe. Backpressure monitoring can also indicate DPF overloading and/or slow soot combustion.

We are pleased to offer a DPF Backpressure Monitor & Logger with features to protect both your engine and your DPF.
