At the 2014 InnoTrans trade fair in Berlin, MANN+HUMMEL and BOLL & KIRCH will present a co-developed system for the treatment of lubricating oil in diesel engines used in railway vehicles which improves the operational reliability and availability of the locomotive and reduces running costs in comparison to conventional solutions.

Speyer, September 23, 2014 – at the 2014 InnoTrans 2014, the leading trade fair for the railway industry, the two leading global German companies in the area of filtration, Boll & Kirch Filterbau GmbH in Kerpen and MANN+HUMMEL GmbH in Speyer, will present their co‑developed solution for the filtration and care of the lubricating oil used in diesel locomotive engines.  The two German companies with global operations and complementary areas of operation have combined their expertise for the benefit of customers and users and the result is the combination of a BOLLFILTER automatic filter and a MANN+HUMMEL oil centrifuge.

The system was developed for the original manufacture and retrofitting of engines. There are numerous advantages for rail operators. For example, the purity of the oil is improved leading to a longer service life. This results in longer oil service intervals and lower maintenance and disposal costs. The solution reduces premature engine wear which improves operational reliability and the availability of the locomotive. In total, the running costs are lower in comparison to conventional solutions without a centrifuge. The experience of the two companies indicates that the amortisation time for the additional investment is between six months and two years.  

Depending on the version, the automatic filter can be fitted to the engine as a vertical or horizontal flange-mounted or slide-in filter. The centrifuge can be fitted directly to the automatic filter or installed in another position.

In the combined system the oil circuit is separated into a main flow with protective filtration and a bypass flow for oil care. The BOLL automatic filter in the main flow filters the complete oil which serves to lubricate the moving parts of the engine. The centrifuge from MANN+HUMMEL in the bypass flow with approx. 10% of the total oil flow takes on the task of removing the entire range of particles including, for example, soot and metal abrasion.
