Hella Hengst focuses on filters

Despite the recent move by motorists away from diesel engines, millions are still being produced and there is an enormous existing vehicle parc, which needs to be serviced. In addition, regular filter replacement is an important part of minimising vehicle emissions and reducing fuel consumption, which must not be forgotten by motor factors or workshops when they communicate with end consumers.

As well as the industrywide problem of under replacement of cabin filters, fuel filters can also be somewhat overlooked. However, should contamination in the form of mineral particles or organic matter enter the fuel system during refuelling and find their way into the fuel injection system, it can cause major damage.

In the case of diesel engines, the filter often performs the additional function of removing free and emulsified water from the fuel as water can cause damage on the high-pressure side as a result of corrosion and insufficient lubrication.

Failure to use high quality filters will exacerbate these issues, which is why technicians should only use an original equipment (OE) filter such as Hella Hengst.

Hella Hengst fuel filters provide reliable protection against particles, as well as water in the fuel, by using high quality filter media, with an extremely high filtration rating, for the effective separation of contaminants.

There are three versions of fuel filter commonly used. The screw-on filter consists of a filter with a permanently connected housing, which is generally located in the engine compartment or under the engine between the fuel tank and the engine and is replaced as a unit during servicing. In addition to the standard interchangeable filters for passenger cars, filters with a water drain plug and a pressure valve are also common.

The in-line fuel filter is a screen or paper filter that is installed between the fuel lines, with a housing made of aluminium, sheet steel or plastic, depending on the application. In-line fuel filters are especially suitable for use in modern petrol fuel injection systems and can be equipped with additional pressure regulators and thermostat valves.

Fuel filters with a filter insert, have a housing that remains on the engine as a lifetime component when the filter is changed. Fuel filter inserts are used both in passenger cars and commercial vehicles.

Hella Hengst uses only thermally recyclable materials in the manufacture of its filter inserts. The Energetic System patented by Hengst (now in its sixth generation) goes one step further with respect to the eco-friendly use of resources and service friendliness. The use of regrind material allows the environmentally safe and cost-effective disposal and recycling of the same-material filter inserts. Installation of the filters is very fast and clean due to the “clip technology” it uses, which prevents potential damage to the insert and requires minimal handling when fitting.

Hella Hengst has recently launched five new fuel filters, four of which are in-line fuel filters and the other an insert. The “Energetic” insert filter E104KP fits several popular applications including the latest Fiat Doblo, 500 and Ducato covering all diesel multijet engine sizes from 1.3, 1.6, 2.0, 2.3 to 3.0 D. This filter also covers all Vauxhall Combo CDTI engines, as well as the Alfa Romeo Guilietta JTD family. The four in-line filters cover a host of modern diesel vehicles including Nissan Quasqai 2.0 and 2.5 DCI, Renault Koleos 2.0 DCI, Mercedes CLS, E, S, Sprinter Viano and Vito CDI. The petrol models covered include Renault Clio, Kangoo and Vauxhall Vivaro.
