Citroen Jumper Diesel Particulate Filter DPF

The Diesel Particulate Filter (DPF) in the Citroën Jumper is a key component of its exhaust system. It is made from ceramic or cordierite and sits after the catalytic converter on the exhaust line to trap harmful soot particles emitted by the diesel engine, reducing particulate emissions by up to 1000 times compared to conventional diesel engines.

The filter uses a porous Silicon Carbide structure with channels that force exhaust gases through the walls, capturing particles larger than 0.1 micron. These particles mainly consist of carbon soot mixed with hydrocarbons, sulfates, sulfur, and metal oxides, which are harmful to health.

The DPF in the Citroën Jumper regenerates to burn off soot particles and prevent clogging through two main methods:

• Passive Regeneration: Occurs when exhaust gases reach 550–600°C during normal driving conditions at higher loads and speeds, burning off soot naturally.
• Active Regeneration: Triggered by the engine control unit when passive regeneration conditions are not met, by injecting fuel into the exhaust to raise the filter's temperature.

Notably, PSA's system uses an additive to lower combustion temperature to about 450°C, improving regeneration efficiency.

Forced regeneration follows a precise protocol to clean the filter thoroughly:

• Maintain engine idle for 2 minutes to warm up exhaust line.
• Increase engine speed to 4000 rpm with post-injection of fuel as required.
• Return to idle for 30 seconds.
• Increase to 3000 rpm to measure differential pressure and assess filter condition.

This procedure helps restore DPF performance and prevent clogging.

DPF maintenance involves cleaning or replacing the filter:

• Cleaning: Using hydrogen decarbonization or chemical unblocking to reduce fuel consumption, emissions, and restore original engine performance.
• Replacement: Includes forced regeneration, cleaning or filter swap, refilling the activation tank, resetting faults with diagnostic tools, and recycling the used product.

Regular maintenance extends the DPF and engine life while preventing costly breakdowns.

The DPF for the Citroën Jumper 250 Van 2.2 HDi 120 CV Diesel (Euro 4 compatible) features:

• Material: Cordierite ceramic
• Weight: Approximately 8.00 kg
• OEM Compatible Number: 1366630080
• Compatible with 2.2D engines since 2011

The DPF includes pressure sensors upstream and downstream to monitor its loading status and trigger necessary regeneration or restrict engine power in case of excessive clogging.

The filter is equipped with upstream and downstream pressure sensors that let the engine control unit monitor the pressure differential (load) inside the DPF. The system defines three zones:

• Zone A: Normal operation
• Zone B: Periodic regeneration needed to reduce pressure differential
• Zone C: Excessive filter overload, leading to engine speed limited to 2200 rpm in reduced flow mode

This system prevents damage by controlling the engine's response based on filter condition.
