Description

Key Responsibilities:

• 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.
  

Qualifications:

• Bachelor's degree in Mechanical Engineering, Automotive Engineering, or a related field.
• 3+ years of experience in powertrain calibration, with a strong focus on emissions systems.
• Experience with gasoline engine operation, emissions systems (including three-way catalysts, lean NOx traps, etc.), and aftertreatment systems (including GPFs, DPFs, SCR).
• Strong understanding of hybrid vehicle architectures and their impact on emissions.
• Experience with engine and vehicle testing procedures and data analysis techniques.
• Proficiency in using engine simulation tools and other engineering software.
• Excellent analytical, problem-solving, and communication skills.
• Ability to work effectively in a team environment and collaborate with cross-functional teams.
• Strong attention to detail and organizational skills.
  
  

Preferred Qualifications:

• Master's degree in Mechanical Engineering, Automotive Engineering, or a related field.
• Experience with HEV calibration, specifically related to emissions control.
• Knowledge of model-based control systems and their application to emissions control.
• Experience with using advanced data analysis tools (e.g., MATLAB, Python).
• Experience with developing and implementing calibration strategies for complex systems.
