1999-2005 : Chief Engineer, Cosworth Technology Ltd.
Functional responsibility for the Calibration department at Cosworth Technology
Ltd. (CTL). Calibration, in automotive terms, is the population of the data
(constants, functions and tables) in the computer software within the Engine
Management System (EMS) to ensure that the vehicle robustly meets all of the
legislative requirements, primarily emissions and diagnostics, as well as
driving acceptably in all ambient conditions (nominally -30°C to +50°C,
and up to 4500m). The main responsibilities of this role were the technical
quality of all the work performed in this area, technical direction of the
Calibration group, project management of all single function projects, the
development of new tools and techniques, business development (including the
preparation and sign off of quotes) and departmental management.
During this period I was also a representative on the Operations group,
which was responsible for the day to day running of the Engineering
division of CTL. And for the majority of this period I also had functional
responsibility for Engine Build and Test, Vehicle Build and Test, Test
Operations, Instrumentation, Metrology, Stores and Logistics
Key areas of development that I was responsible for during this period
:
Certification - The Calibration department recently completed it's first US
certification, prior to this all certification work had been completed by
the clients, completing all the required documentation and liaising with the
appropriate legislative bodies the California Air Resource Board (CARB) and
the Environmental Protection Agency (EPA). The Calibration department also
supported the European certification of this vehicle and had also performed
the modifications to the calibration for the engine from it's donor vehicle
a 4WD automatic into it's new vehicle a rear wheel drive manual sports car.
Integrated Data Acquisition and Analysis (IDAA) - This is a tool suite
that automatically provides statistical analysis of engineering data. It
was developed to give an indication of On Board Diagnostic (ODB)
Robustness but has since proved its worth in proving the reliability, and
over checking, of calibrations in general, the automatic generation of
status against targets for internal Measures Of Success (MoS) and batch
the post processing of other engineering data.
Master Proving - During the last six years the Calibration department
developed a web based toolset to report the functionality of the
diagnostic system, i.e. to test all the diagnostic fault paths to ensure
that they correctly illuminate the Malfunction Indicator Light (MIL).
Calibration - My department performed a significant number of
calibrations including full calibrations (total responsibility), partial
calibrations (responsible for particular functions e.g. base mapping,
emissions or cold start), diagnostic calibrations, demonstrator
calibrations (concept, technology, performance and emissions - for
vehicle up to 100hp/litre (NA) and 160hp/litre (T/C).
Modelling / Simulation - The development of tools and techniques to calibrate
and validate a calibration off line primarily using the Matlab / Simulink
and MBC toolbox. This has allowed us to calibrate multi degree of freedom
engines (primarily direct injection) using a combination of design of experiments
(DoE) and traditional sweep techniques. It has also allowed the validation
of models within the EMS software to the real world (e.g. charge and torque
model).
1997-1998 : Senior Principal Engineer, Cosworth Technology Ltd.
Project Leader on high performance luxury sports car. Responsibility for developing departmental procedures, in particular for climatic testing and sign off.
1996-1997 : Principal Engineer, Cosworth Technology Ltd.
Project Leader on TOPS 8D investigation into pull away stumble on a mainstream vehicle, an ISC re-calibration for a mainstream vehicle, a re-calibration for a mainstream vehicle to meet D3 emission levels, a calibration project using EECV to meet all aspects of Federal and European certification for a high performance luxury sports car, including performance, emissions and diagnostics.
1986-1996 : Jaguar Cars Ltd.
I started as a sponsored student at Jaguar, and after obtaining my degree (BEng. Hons.) at the Victoria University of Manchester, I joining the Calibration department where I performed work using both the Denso EMS and the Lucas 15CU system.
