Key Responsibilities - Plan, execute, and support vehicle, powertrain dynamometer, and/or engine dynamometer testing at internal facilities and external vendor locations.
- Support testing and validation of low-emission technologies against future emissions standards, including ACCII Stand Alone US06.
- Identify potential calibration concerns and issues encountered during testing and communicate findings to technical specialists for resolution and guidance.
- Perform post-processing of test data files using supplied or alternative vendor tools.
- Extract and analyze key statistics for emissions compliance and calibration assessment.
- Conduct detailed analysis of emissions test data and provide data-driven recommendations to optimize calibrations and address issues.
- Summarize test findings, data analysis results, and recommended actions through clear technical presentations.
- Use data visualization methods such as boxplots and modal cumulative plots to communicate technical information.
- Track and maintain accurate records of test vehicle status, including fuel types, hardware configurations, calibration levels, and relevant modifications.
- Participate in test planning to ensure testing aligns with program goals and timelines.
- Prepare and submit Test Requests (TRs) on a weekly basis to facilitate required testing activities.
- Develop, optimize, and validate full-cycle emissions calibrations, including cold start, warm-up, and hot stabilized conditions.
- Support calibration activities targeting SULEV30, ACCII, and Tier 4 gaseous and particulate matter tailpipe emissions standards.
- Develop data acquisition lists and record data using appropriate acquisition software.
- Verify data integrity, including sample rate, alignment, and reasonable parameter values.
- Develop naming conventions and data storage systems that allow test files to be easily located and accessed.
- Evaluate test data and develop changes to engine emissions calibration to reduce tailpipe emissions and optimize aftertreatment performance.
- Execute predefined test plans and apply structured problem-solving processes to resolve technical issues.
- Prepare technical documentation, spreadsheets, and presentations to communicate testing, findings, and next steps.
