  • conversion of generated electrical energy into heat using resistive load
  • effective silencing at intake and exhaust for laboratory operation
  • sensors record all relevant data visualised on displays in the process schematic

The unit consists of a wheeled frame made of steel, of a panel with mimic diagram carrying the measurement instruments and of a base where the main components are installed, that is the combustion chamber, the turbo charger assembly, the power turbine and the alternator. The exhaust gases produced by the combustion of the compressed air/gas mixture are made to expand first through the turbine of the turbo charger assembly in order to supply the energy necessary to compress the air and then through the power turbine coupled to the alternator through a toothed belt. The electric energy generated by the alternator is dissipated on a resistive load. The unit is supplied with manuals which describe all parts of the trainer, the installation and utilization procedures, as well as many exercises with the relative results.
