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.

By leveraging new tools and advanced technologies, Dumarey is elevating its engine engineering approach toward a smarter, faster and more efficient Design & Release process.

A concrete example is the integration of multi-CAD capabilities combined with Additive Manufacturing (3D printing), which significantly reduces prototype lead time and eliminates proto-tooling costs.

The main objective of Dumarey’s engineering services is to optimize engine performance and emissions through targeted testing activities. By leveraging strong in-house capabilities and fully equipped testing facilities, including testing labs, engine dynos and roller benches, Dumarey is able to assess, refine and validate engine hardware with precision and speed.

As a fundamental driver of innovation, Dumarey applies advanced engineering to develop new technologies from R&D through to production, integrating them into new products that fully meet project targets. Through a rigorous system-engineering approach, we balance technical content, cost and product competitiveness to ensure optimal value creation.

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

Noise, Vibration & Harshness (NVH) refinement is a core mission at Dumarey. From the earliest stages of product development, we apply a design-thinking approach supported by both computational analysis and experimental testing.

Dumarey applies cost engineering methods to manage “product value” as the balance between functional performance, cost and market competitiveness, starting from the initial concept and continuing throughout the full development cycle.

Taking advantage of new tools and technologies, Dumarey has developed a smarter, faster and more efficient design & release process.
