The activities involve the following steps: Performing test plans on the engine test bench in both steady state and dynamic calibration. The engineer has to make sure the tests are run in the proper way and at the appropriate timing with respect to the project plan Analyse and process through specific tools the data from the engine bench in order to populate the calibration maps in such a way to meet the key performance indicator metrics on performance, functionality of the engine and of its components, accuracy of the models Verification and validation of the calibration data on both engine test bench and vehicle Collaboration along with the whole calibration team in the continuous process of defining more effective and efficient calibration methodologies and tools. At an early stage of the project the engineer may be involved in the process of performing tests to provide data helpful to define the choice of the engine HW (e.g. turbomatching, valves timing and lifts).

Development engine simulator to test the logic of management after treatment system (ATS) for post Euro 6 emissions legislation TUTOR TUCCI Vittorio Antonio HIL (Hardware In the Loop) Specialist HIL simulators allow simulating the neighbourhood around an electronic control unit to allow design, calibration, verification and validation for the control software. Each HIL requires specific design, setup and test to reach the requested level of accuracy, repeatability and reliability in order to perform the planned activities. For Powertrain domain, electronic control unit tested on HIL are engines, transmissions and drivelines management systems. Thus, main tasks are the following: Definition of HIL specifications for the selected ECU (including wiring harness, real and emulated components) Development and maintenance of powertrain models Validation of HIL simulators (I/O and models) Development and maintenance of test automation platform Design, setup, configuration and validation of a system HIL for an engine management system for a diesel engine equipped by SCRoF (SCR on Filter) ATS strategies for Passenger Car applications: Definition of HIL specifications for SCR system, investigating the possibility to emulate real loads as urea injector and pump Development and validation of ATS models in order to perfom model based calibration Development of automated testing for SCR system
