Motorservice was showing a successful and exclusive innovation at Automechanika being the only supplier in the aftermarket to offer an electric pump designed for purging activated carbon filters (ACF). 

The ACF pump 7.11390.00.0 was developed by Pierburg in Germany and launched as a world first in 2018. Since then, it has been increasingly used by a large number of renowned car manufacturers in their series production and as a result offers considerable potential in the aftermarket. The pump feeds the fuel vapours from the ACF back into the combustion process, reducing the vehicle's pollutant emissions.

It consists of a centrifugal electric gas pump driven by a single-phase motor and operates at a throughput of up to 50 litres per minute while the pressure remains at only 0.1 bar (approx). Its thermal resistance is increased by innovative active cooling technology used on the electronic components. This ensures that the pump can withstand the harsh conditions in the engine compartment. It is also fitted with an integrated pressure sensor, which informs the vehicle control unit of the system pressure.

Also on display was the new expanded range of MS Motorservice oil coolers with 37 new items for passenger cars and utility vehicles, available as engine oil coolers and as transmission oil coolers. For passenger cars, the oil coolers are supplied under Pierburg brand. 

Engine parts subject to high stress, such as the pistons, use engine oil not only for lubrication and as a sealant, but also for cooling. The oil circulates through a closed circuit from the oil pan to the oil pump and on to the moving parts of the engine, before returning to the oil pan. An oil cooler integrated into the oil circuit provides additional cooling. Modern oil coolers have a plate-based structure, with several plates lying on top of one another and forming separate channels. These channels alternate between ones filled with oil and ones filled with coolant agent. To improve the heat transfer, the channels have structures to increase the surface area.

The Pierburg oil cooler range offers an effective aftermarket alternative for these components, combining excellent performance, long service life and value. They are available from Pierburg stockists.
