Engine Performance Calibration

Job Title Engine Performance Calibration

Work Location: Auburn Hills, MI

Responsibilities:

• Perform engine dynamometer calibration and development activities for gasoline engines.
• Develop, optimize, and validate base engine calibration datasets to achieve performance, fuel economy, emissions, drivability, and robustness targets.
• Calibrate airflow models, fuel flow models, torque models, calculated MAP models, catalyst and exhaust temperature models, and other combustion-related control algorithms.
• Develop and optimize spark timing surfaces, minimum spark surfaces, knock control strategies, off-nominal spark adjustments, and cam phasing surfaces.
• Calibrate maximum tip-in cam strategies, transient response models, and engine protection functions.
• Support engine-out emissions calibration and cold-start emissions strategies.
• Conduct combustion analysis, engine performance optimization, and emissions trade-off studies.
• Utilize dyno automation and test scheduling systems to maximize test cell utilization.
• Analyze large volumes of test data and implement calibration improvements.
• Ensure calibration dataset management, version control, documentation, traceability, and release compliance.
• Collaborate with controls, combustion, emissions, software, and validation teams.
• Present technical findings and calibration results to internal and customer teams.

Requirements:

• Minimum 10+ years of experience in engine dynamometer calibration and engine performance development.
• Minimum 5+ years of gasoline engine calibration experience.
• Strong understanding of combustion fundamentals, engine controls, calibration methodologies, and emissions regulations.
• Hands-on experience with airflow and fuel flow modeling, spark and cam phasing calibration, knock calibration, calculated MAP and torque model development, catalyst and exhaust temperature modeling, cold-start emissions calibration, and drivability calibration.
• Experience with standard dyno equipment, emissions measurement systems, CAS, and engine test laboratory instrumentation.
• Proficiency in ETAS INCA, MATLAB/Simulink, Microsoft Excel, and Base Engine Calibration Toolkits/internal calibration analysis tools.
• Strong knowledge of calibration dataset management, release processes, and change control practices.
• Experience working with large datasets and data-driven problem-solving techniques.
• Excellent communication and cross-functional collaboration skills
