alma automotive: custom solutions for engine development and testIng

 ENgine calibration

  • Ion signal controller: definition of ion current-based indexes for best correlation with pressure signal
  • Optimal parameters calibration (common rail) methodologies
  • Automatic calibration of Prail and VVT (Intake, Exhaust) for GDI engines (Matlab-INCA)
  • SCR control parameters calibration
  • Complete engine calibration on the test bench for complex engines (GDI, turbo, roots, VVT, EGR, etc.) on UNIBO test bench 

 

Calibration

 

Engine-vehicle behavior analysis

  • High-speed camera acquisition and synchronization with engine signals: the system has been used for various purposes, such as sliding clutch evaluations, air entrainment into engine lubricant
  • Turbocharger speed estimation based on acoustic emissions
  • On-board stereoscopic image acquisition of tyres for deformation evaluation
  • Torque-meter based on shafts torsion
 
engine-vechicle


driveline-vehicle modeling

  • Simulink models, with the ability to simulate torsional oscillations: used for traction control strategies definition (SIL, up to>40 dof)
  • Simplified models for HIL systems, integrating engine, clutch, gearbox and driveline simulations
  • Detailed vehicle dynamics models (effect of wheel torque/steering angle on vehicle behavior, effect of electric motor torque on vehicle stability)

ENGINE-COMPONENTS MODELING

  • Detailed model of engine portions/components have been developed, to define control or diagnostic algorithms
  • Dual Mass Flywheel, turbocharger, tank/canister circuits, driveline dumpers, internal EGR, combustion 
  • Test-bench joints modeling for torsional vibration evaluation
  • Engine thermal modeling for thermal management
  • Sensors modeling (UEGO, in-cylinder pressure, etc.)
