Key Responsibilities:
Qualifications:
Preferred Qualifications:
- Develop and execute calibration strategies for GPF systems on HEVs, including:
- Soot Loading Control:
- Develop and implement strategies to minimize soot accumulation in the GPF under various driving conditions.
- Optimize regeneration strategies to effectively remove soot from the GPF while minimizing fuel consumption and emissions (e.g., NOx, HC).
- Analyze and address potential issues related to soot loading, such as excessive soot accumulation, incomplete regeneration, and filter plugging.
- PM Emissions Control:
- Calibrate engine and aftertreatment systems to minimize PM emissions across the entire vehicle operating range, including transient and steady-state conditions.
- Analyze and optimize GPF performance parameters, such as filter efficiency, pressure drop, and regeneration frequency.
- Gasoline Emissions Control:
- Collaborate with other calibration engineers to ensure optimal control of gasoline engine emissions, including NOx, HC, and CO, while minimizing their impact on GPF performance.
- Analyze and address potential interactions between gasoline engine emissions and GPF operation.
- Conduct bench and vehicle testing to evaluate GPF performance and validate calibration strategies.
- Analyze test data using advanced data analysis techniques to identify trends, diagnose issues, and optimize calibration parameters.
- Utilize engine simulation tools and other engineering software to model and predict GPF performance.
- Develop and maintain calibration documentation and reports.
- Collaborate with other engineering disciplines, such as engine design, aftertreatment development, and controls engineering, to resolve technical challenges.
- Stay abreast of the latest advancements in emissions regulations, aftertreatment technologies, and hybrid vehicle architectures.
- May be required to support occasional travel for testing and meetings.
