WCX 2025: Dumarey Launches U.S. Subsidiary for Better ICEs

With continued expansion, Dumarey is helping internal combustion engines expand their diet to include hydrogen, methanol and more.

The Dumarey Group used WCX 2025 as the launching point for its new U.S. subsidiary, Dumarey USA. Dumarey, a Belgian family-owned company, announced the acquisition of Mahle Powertrain LLC in January and said in Detroit that the transition to Dumarey’s new North American engineering and testing hub is now complete.

Expanding its North American footprint is the latest way the Dumarey Group is focusing on its main mission: preparing internal combustion engines for their last hurrah. In early 2024, for example, Dumarey acquired Vitesco Technologies Italy because of its experience with various injectors, bringing more injector engineers and product teams on board. The previous Vitesco plants are now producing gasoline urea injectors for Dumarey and, in the future, they will build injectors for hydrogen engines, according to Vincenzo De Carlo, Dumarey senior program manager and chief engineer. It’s all part of the plan, even Dumarey isn’t betting everything on H2.

“The target is to create what our boss is calling ‘the product,’” De Carlo told SAE Media at WCX. “In his mind, the product is a final engine. All the acquisitions we are doing are linked with the product. In this moment, the main product is the hydrogen engine and, later, the fuel cell. The acquisition of Vitesco was to develop a hydrogen injector. The acquisition of Dumarey USA was to develop in the U.S. this kind of mentality. In general, we are working on all kinds of eFuels in general. Methanol, ammonia, hydrogen, whatever is coming, we are in a development phase for all of it.”

De Carlo said Dumarey’s target is to be producing nitrogen injectors by 2030, but that’s only part of the challenge.

“It was difficult to develop the software that would allow us to manage all the different fuels because each different fuel has to be driven by specific software,” De Carlo said.

For example, when used with hydrogen, the injectors need to deliver H2 at low pressure, not more than 40 bar, De Carlo said. That’s less pressure than gasoline injectors use and much less than the fuel storage tank. “The starting point is the 700 bar in the tank and then we reduce this in the line to achieve 40 bar, not more, because this is the market request,” he said.

At WCX, Dumarey displayed its 250-kW, hydrogen V8 6.6-L port fuel injection engine alongside next-generation hydrocarbon injectors and liquid-cooled heavy-duty urea injectors that have been developed to address new EU7 emissions regulations. The Dumarey electronic platform, for example, is a scalable, multi-purpose 12-24V-capable controller for spark or compression ICEs as well as for alternative fuels like hydrogen.
