System Calibration Support

Calibration is the process which ensures the proper performance of the system and the achievement of the application targets: emissions, driveability, performance and functionality. Synerject is able to undertake a complete system calibration project (turn-key calibration) or provide a menu of support for customers who prefer to handle the calibration activities partially or completely on their own.



System Calibration

Engine Characterization (Basic Calibration)

Engine characterization is the activity to determine the basic parameters for engine control such as fuelling or ignition advance. It is done at the engine dyno, preferably by the customers in their facilities.

The Synerject calibration team provides support to our customers for engine characterization. The support includes:

  • Recommendations for engine instrumentation
  • Delivery of a detailed calibration guideline
  • Delivery of a preliminary system calibration
  • Support on engine start and run-in
  • Characterization of engine air flow, ignition and air/fuel ratio at each engine operating point
  • Emission measurements and catalyst efficiency determination
  • Engine data analysis and first calibration issue for on-vehicle first start.

Vehicle (Final) Calibration

The achievement of the application targets (especially emissions versus driveability trade off) requires complex software functions with hundreds of adjustable parameters. Synerject is able to perform turnkey tuning of these functions in order to meet our customers' expectations on start-ability, driveability, emissions and vehicle function performance.

Synerject is also able to support our customers in all the following calibration activities:

  • Vehicle hardware configuration
  • Warm up
  • Cold start
  • Drive-ability optimization
  • Emission optimization
  • Robustness verification (production dispersion, mileage)
  • Diagnosis tuning
  • Hot trip / Cold trip / Altitude trip

Validation and Fleet

The final validation of system components and calibration is achieved through the monitoring of sensitive system parameters during fleet tests. The fleet is usually performed by the OEMs. Synerject is able to provide support for:

  • Test definition (mileage, running conditions etc.)
  • Parameters collection and analysis

The final validation of system components and calibration is achieved through the monitoring of sensitive system parameters during fleet tests. The fleet is usually performed by the OEMs. Synerject is able to provide support for:

Exhaust Emission Homologation Certification

If required by our customers, Synerject is able to provide support for emissions homologation or perform the complete emission certification on behalf of our customers. Synerject has easy access to all the certified test facilities at Continental locations in North America, Europe, China and India, as well as other local institutes close to our customers.
