Motorsports Propulsion Development Engineer - Engine Simulation
Today• Concord, NC
Pontiac, MI
Description
Hybrid: This role is categorized as hybrid. This means the successful candidate is expected to report to Pontiac, Michigan or Concord, NC three times per week, at minimum.
The Role
The Motorsports Propulsion Program Team is seeking an expert in engine simulation methods to lead the virtual engineering aspects of engine programs. As a subject matter expert, you will be responsible for engine performance simulation and valvetrain analysis models using 1D virtual tools. Functions include model building, correlation and evaluation. You will manage multiple projects and provide technical insight into problem solving, leveraging the model results for hardware, and calibration development.
This position requires a fundamental understanding of combustion engines and the modeling approach via GT-SUITE 1D CFD Software. These engine models are the core estimation for performance and fuel efficiency for early vehicle architecture development. This role also leverages the large design of experiments and optimization using 1D modeling to solve complex and multivariable problems.
What You'll Do
- Develop 1D engine simulation models in GT-POWER of a wide variety of engine architectures with complete intake and exhaust systems
- Simulate full and part-load models focusing on torque, power and fuel consumption
- Process lab and model generated engine operating data (fuel mapping) into standardized format
- Execute transient engine simulations to support engine control algorithm evaluation and/or development (HIL/SIL), and vehicle performance assessment
- Create Medium or Fast Running Models (MRM / FRM) to support controls development activities
- Develop new and innovative analytical techniques to model engine technologies (boost devices, exhaust gas recirculation, variable valve lift, emission control systems, aftertreatment etc.) with emphasis on minimizing test data requirements
- Develop optimized valve lift profiles using parametric valvetrain design software
- Provide component-level and/or system-level design recommendations to Design Responsible Engineers based on interpretation of analysis results
- Participate in product design and development teams and regularly present analysis results to engineering peers and management
- Appropriately distill 3D math data into 1D model geometry using the correct discretization techniques
- Cooperatively work with test engineers to develop and/or enhance laboratory procedures to validate system analysis results
- Contribute to the development of post-processing and automation tools using MATLAB and/or Python
