Position Description:

Emissions Calibration / Aftertreatment Engineer is required to plan and deliver bench-aged aftertreatment systems to support calibration and certification activities.

Bench-ageing is an accelerated ageing process currently conducted on an engine test bed to an approved process. There is an existing test bed set up on a JLR facility for aftertreatment ageing, running an automated cycle.

The role involves:

  • Compiling ageing requests from calibration and certification teams (customers).
  • Planning and prioritising requests and seeking escalation when conflicts are unable to be resolved.

  • Monitoring test bed data and ensuring ageing is conducted correctly to process.
  • Producing reports for each system and confirming ageing duration, temperature profiles and oxygen storage before issuing parts to customer.

Skills Required:

  1. Familiarity working with engine test beds, understanding of basic engine control parameters to deliver required exhaust mass flow rate, temperature, lambda, urea dosing.
  2. Understanding of basic aftertreatment function and ageing impacts (light-off, oxygen storage capacity).
  3. Ability to analyse and interpret engine / test bed data using INCA / MDA, Concerto, Matlab

Experience Required:

  • Experience in engine / aftertreatment calibration or aftertreatment system development.
  • Experience using engineering tools such as INCA / MDA, Concerto, Matlab.
