Hardware Engineering for Propulsion Systems

We design and develop propulsion systems from concept to serial production, taking a flexible and agile approach.

We deliver turnkey engines that leverage our cross-functional engineering skillset.

Thanks to new tools and technologies, our design and release process is now smarter, faster, and more efficient.

Our multi-CAD experts work with additive manufacturing (3D Printing) to deliver custom engine prototypes quickly and reduce costs due to proto-tooling.

Engineering Expertise

• CAM/CAD engine design​
• Digital Mock-up
• Custom Engine Design
• Turnkey Engines
• Virtual Prototyping
• Materials Engineering
• Additive Manufacturing​
• Production Release​
• Design Guidance, Standard Works and Development Methods
• Designers, Specification Analyst Engineers, Components’ Design Release Engineers, Design System Engineers

We optimise system performance and reduce emissions through in-depth testing. Our in-house testing labs use dynos and roller benches to test performance of our propulsion solutions. Then, we thoroughly assess the engine hardware.
This intensive pre-production process ensures we can set up, measure, and deliver custom engines fast.
Our approach is integrated, developing the hardware and software simultaneously for optimal testing.

Engineering Expertise

• Engine Emission & Performance Optimisation​
• Specific Capability on Emission Reduction Technologies to meet Global Requirements (Europe, US, China) ​ for Propulsion Solutions
• Concept and Hardware Selection, Development at Component and System level​
• Thermo-Mechanical Durability Validation and Endurance Testing​
• Designing Custom Engines

We prioritise innovation, developing new technologies from R&D to production. Our integration engineering, adds new technologies to custom-built products, designed specifically to achieve project targets.
Balancing cost and technical requirements, our engineers use systems engineering techniques to ensure the product is both cost-effective and competitive.

Dumarey’s virtual prototyping and engineering capabilities reduce hardware dependency and related costs, accelerating development, enhancing efficiency, and improving quality.
We extensively use simulation methodologies to optimise structural behaviour, NVH, airflow, combustion, thermal management and aftertreatment. Our approach applies modern automation techniques, digital twin, artificial intelligence, and machine learning.

Engineering Expertise

• Structural and NVH Analysis​
• Computational Fluid Dynamics (CFD)​
• System Simulation and Virtual Calibration

Reducing noise, vibration, and harshness is one of our key missions. We improve the NVH in our propulsion solutions by leveraging computational analysis and experimental testing. Our team takes both approaches simultaneously to ensure continuous data exchange for model updating and accurate early NVH prediction using the internal state-of-the-art Hemi-Anechoic Dyno.

Engineering Expertise

• Sound Power Level
• Experimental Modal Analysis and Vibrational Mapping
• Combustion Noise in-vehicle optimisation
• Sound Quality and Psychoacoustics

We work with our customers from the early stages of pre-development, analysing product competitiveness and design-to-cost activity. We assist with component negotiations, assisting the Purchasing Team in discussions with suppliers by providing data-backed cost targets/cost gap analysis/cost sharing. After the sourcing phase, we continue cost optimisation throughout the development process.

Engineering Expertise
