Deutz is strengthening its expertise to make combustion engines more efficient and cleaner, by acquiring a stake in HJS Emission Technology, a specialist in exhaust gas after treatment. To this end, both parties signed an agreement under which Deutz will acquire 50 percent of the shares in HJS.

As a medium-sized family business based in Menden/Sauerland (Germany), HJS Emission Technology stands for many years of experience in the field of exhaust gas aftertreatment, especially for diesel engines. With around 300 employees, the supplier develops, manufactures and markets electrical and mechanical components to reduce pollutant emissions. Due to the contractually agreed governance structure, Deutz will consolidate the company within the Group going forward.

“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,” says Deutz CEO Dr. Sebastian C. Schulte. “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 specialist 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.”

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.

The closing is scheduled to take place at the beginning of 2025 after receipt of merger control clearance.
