Particle filter injection units
From the specialist in emission control
Information on the product
The particulate filter injection units expand the Motorservice product range for emission control, and are essential components for effective particle filter regeneration. They precisely inject fuel slightly upstream of the particulate filter to break down soot particulates and minimise emissions. The use of corrosion- and temperature-resistant materials in the manufacturing process ensures the long-term high quality of the entire system, while innovative solutions further optimise the practical use of these components.
The consistent use of this technology not only helps reduce harmful output values, but also enables the replacement of necessary spare parts without any problems and in doing so promotes the sustainable operation of modern engines.

Motorservice is expanding the product range for emission control with particle filter injection units. The 14 articles cover a global vehicle fleet of over 7 million vehicles.
These injection units are an essential component for regenerating diesel particle filters.
Products from the specialist for emission control
High operating temperatures and aggressive exhaust gas place high demands on the components. The corrosion and temperatureresistant materials used in Pierburg products ensure lasting function under the harshest conditions. There’s a reason why Pierburg is represented as an OEM in a large number of modern vehicles.
That is why we are constantly expanding our product range.

The injection unit consists of the following components:
01 Fuel supply line (material: FKM)
02 Power supply to the heating element
03 Heating element
04 Hollow screw with retaining washer for screwing the injection unit to the exhaust pipe
05 Injection nozzle, protected by plastic cap when delivered
In addition to other pollutants, the combustion process in diesel engines produces soot particulates. They are made of carbon, onto which various compounds are deposited, including hydrocarbons that are harmful to health. For this reason, the soot particulates are filtered out and collected in the diesel particle filter (05).
At high exhaust gas temperatures above 550 °C, such as when driving on the motorway, the soot burns to form carbon dioxide and water vapour (known as “regeneration”).A small proportion of non-combustible ash is left behind. The particle filter must, therefore, be replaced after approx. 200,000 km.
Frequent short journeys, the use of poor-quality engine oil or defective attachments such as glow plugs, EGR valves or sensors will increase the amount of soot deposited in the filter. To prevent the particle filter from becoming clogged prematurely and thus being damaged, a differential pressure sensor (02) monitors the extent to which it is soiled.

When a certain soiling limit has been reached, the particle filter (05) must be actively regenerated. To do this, the engine control unit starts a free-burning process in order to achieve exhaust gas temperatures of over 550 °C:
in certain operating and load states, the injection unit (01) sprays in fuel just upstream of the particle filter (05). The fuel burns with the residual oxygen in the exhaust gas. The resulting heat also heats up the particle filter.
Depending on the specific vehicle and driving conditions, the active burning-off process takes place roughly every 400 to 600 kilometres and lasts around 10 minutes. It usually goes unnoticed by the driver. It does not impair the engine performance. The free-burning process can also be started in repair shops using an engine tester
