DEUTZ Strengthens Clean Engine Expertise with HJS Acquisition

DEUTZ acquires 50% of HJS Emission Technology, a specialist in cleaner, more efficient combustion engines, DEUTZ will source more exhaust gas aftertreatment systems internally through HJS.

Cologne, Germany- DEUTZ AG., is enhancing its expertise in cleaner combustion engines by acquiring a 50% stake in HJS Emission Technology GmbH & Co. KG,  in exhaust gas aftertreatment. The deal, signed in November, is set to close in early 2025, pending merger clearance.

HJS Emission Technology, a family-owned business based in Menden, Germany, brings decades of expertise in diesel engine exhaust gas aftertreatment. With a workforce of around 300, the company designs, produces, and markets components to reduce pollutant emissions. Under a newly established governance structure, DEUTZ will integrate HJS into its Group while continuing to rely on the experienced leadership of CEO Robin Trompetter and his management team.

Dr. Sebastian C. Schulte, DEUTZ CEO, said, "The combustion engine is not a discontinued technology. This is certainly true for applications where machines are constantly in use and move large loads. The technology will therefore continue to be of strategic importance to us in the future. Resilience in the supply chains is correspondingly important to us. This is especially true for key components in the field of exhaust gas aftertreatment, which enables cleaner engines. HJS Emission Technology is a technology leader in this field, with whom we and other established companies have been working well for years. With our investment in the company, we ensure that these critical components will continue to be reliably manufactured and sourced for us and other customers via HJS Emission Technology in the future. This strategic step also shows that DEUTZ is consistently committed to Germany as a business location and that we are taking a stand against deindustrialisation in our areas of activity."

With this step, DEUTZ is continuing its active role in consolidation in the combustion engine market. In the future, it is planned to purchase a large part of the components and systems required for exhaust gas aftertreatment of selected engine series from HJS Emission Technology and thus from the own Group. To this end, the relevant business of a previous DEUTZ supplier will also be relocated in 2025.

DEUTZ's commitment forms the basis for the HJS Emission Technology's future profitable growth and thus secures its future development and positioning as a consolidator in the field of exhaust gas aftertreatment. In addition to HJS Emission Technology's core competence as a system provider for exhaust gas aftertreatment in the on- and off-highway sector, the company is active in other relevant fields, such as service, motorsport, industrial filtration, and inland waterway vessels. The goal is always to reduce emissions.
