Common DPF Problems

A diesel particulate filter captures soot and other exhaust contaminants before they leave the exhaust system. The filter must periodically complete a regeneration cycle to burn the accumulated soot.

Frequent or interrupted regeneration can increase fuel use and vehicle downtime. It may also lead to warning lights, reduced power or recurring maintenance. The impact depends on the engine, duty cycle and operating conditions.

 

Benefits of PACCAR DPF Delete Tuning

Eligible off-highway operators may consider DPF delete tuning for three main reasons:

• Engine response: A properly calibrated tune may support smoother power delivery and faster throttle response.
• Fuel use: Fewer regeneration cycles may reduce the fuel consumed during the regeneration process.
• Maintenance: DPF delete tuning may reduce maintenance linked to the filter and regeneration system.
