The Gasoline Aftertreatment Technology Expert will handle investigating and developing gasoline aftertreatment systems (ATS) technologies to meet required emissions standards (e.g. TIER4, California LEV IV, EURO7, China 7, PL8, etc.) for future propulsion applications. Development activities will focus on three-way advanced catalyst (TWC) technologies and gasoline particulate filter (GPF) using a demonstrated strong background in substrate, filter, and catalyst washcoat and platinum group metal (PGM) development.
This position is on-site at the Chrysler Technology Center in Auburn Hills, MI. The Gasoline Aftertreatment Technology Expert will demonstrate proof-of-concept solutions to ensure Propulsion functional objectives are satisfied. Projects will utilize engine dynos, vehicle chassis dynamometers, and/or simulation/modeling to make physics-based decisions.
The Gasoline Aftertreatment Technology Expert will have the following responsibilities:
- Demonstrate proof-of-concept solutions to prove Propulsion System functional goals are satisfied utilizing engine and vehicle chassis dynamometers and/or simulation/modeling to make physics-based decisions
- Investigate new, innovative emissions system technologies such as advanced catalyst technologies and optimized, low PGM solutions Develop ATS solutions for future vehicles that account for system trade-offs of cost, performance, complexity, etc., while meeting all quality and regulatory requirements
- Develop requirements for catalyst component plant and control models (including catalyst and aging characterization) Develop TWC system requirements for HW, controls, and calibration
- Define and direct multiple externally based technology development projects at both suppliers and/or partners to meet ATS critical needs
- Plan, test, analyze, and solve complex system problems as they relate to the entire propulsion system to meet key objectives such as powertrain performance, emissions, diagnostics, NVH, quality, fuel economy, etc.
Support quality improvement efforts, share lessons learned from internal and post-production experience to prevent future recurrence, and perform benchmarking analysis Lead and/or support production development activities leading to and enabling vehicle launch (ATS procurement, supplier interactions, PPAP, APQP, aging, etc.) This position will report directly to the US-based Manager for Emissions and Aftertreatment and operate under the general direction of the Global Director for Emissions and Aftertreatment.
Basic Qualifications
