Design and optimize combustion chamber geometries for improved efficiency, power output, and emissions performance.
Simulate and interpret combustion processes, heat transfer, cold start behavior, and catalyst heating strategies.
Provide component-level and/or system-level design recommendations to Design Responsible Engineers based on interpretation of analysis results
Exercise analytical models for fuel preparation and mixture motion analysis including equivalence ratio and wall wetting
Model and analyze fuel injector behavior, spray atomization, spray-wall interaction, and mixture preparation.
Exercise analytical models for in-cylinder combustion analysis using 3D CFD codes such as Star-CD, Converge, AVL-Fire, or in-house proprietary software
Enhance current standard analysis practices and/or tools to improve prediction fidelity and/or execution speed
Participate in product design and development teams and regularly present analysis results to engineering peers and management
Document analysis objectives, conclusions, results, and assumptions using a standard report template
Cooperatively work with test engineers to enhance laboratory procedures to support the development of first-time capable analysis techniques
Stays abreast of new technology and competitive products
Collaborate with cross-functional teams including engine design, calibration, controls, and emissions compliance.
Validate simulation results with experimental data and iterate designs accordingly.
Document and present findings to technical leadership and project stakeholders.
