Gainsborough-based emission specialist Eminox has agreed a deal with engine manufacturer Liebherr Machines to jointly develop and manufacture Stage V standard exhaust aftertreatment systems (EATS).
Thanks to advanced exhaust aftertreatment technologies, including an SCR-coated DPF, the EATS can achieve reductions in particulate number count (PN), as well as the continued tight control of NOX.
The UK company, which has worked with Liebherr for many years, has previously supplied silencers, pipework and specialist spark arrestors, as well as working on the former generation of EATS – which are currently in volume production.
With Stage V legislation announced soon after the implementation of Stage IV, to avoid the need for machine redesign, the collaboration set out to maintain the components’ space envelope. This means the new design is almost identical in package to its predecessor.
Additionally, the partnership will work together to develop high-power engines (HPE) and low-power engines (LPE), which will launch in 2019.
However, the HPE ranges present additional challenges in terms of packaging – a linear system, as developed for LPE, would not fit the available space envelope and meet the backpressure target. The solution involved developing a twin system, which will mean it can be integrated into a wide range of existing machines without redesign.
Mark Runciman, operations director for Eminox, said, “Eminox is continuing to expand its OE business and we are thrilled that Liebherr has continued to trust in our development and manufacturing expertise.”
