Injection Nozzle Development and Optimization
Industries Automotive Engineering

To develop and optimize injection nozzles, a combination of advanced CFD tools such as Ansys Fluent, Siemens Star-ccm+ and AVL Fire is typically used. This includes a one-dimensional model of the entire fuel injection system, from the fuel tank to the injector, as well as a 3D CFD solver to focus on the fluid flow inside the injection nozzle itself.

The one-dimensional model is used to simulate the behavior of the fuel system as a whole, including the fuel pump, fuel lines, and pressure regulator. This allows engineers to optimize the overall performance of the system, ensuring that the fuel pressure and flow rate are optimized for the specific engine and operating conditions.

The 3D CFD solver is then used to simulate the fluid flow inside the injection nozzle itself. This includes modeling the injection process, fuel spray pattern, and combustion characteristics. By optimizing the design of the injection nozzle using CFD simulations, engineers can improve fuel atomization, reduce emissions, and optimize engine performance.

Automotive Engineering

We focus on strategic use of CAE to Optimise Designs, investigate and resolve problems, and minimise time and cost to market. Advanced geartrain modelling and analysis software packages, provides the foundation of concept and definitive design for all driveline and transmission projects that we undertake.

Powertrain component development involves the design and optimization of various components such as engines, transmissions, and axles. FEA and CFD-based simulation can be used to evaluate the structural integrity, fluid dynamics, and thermal performance of these components, allowing engineers to optimize designs and improve performance.
