| description | This paper discusses the evaluation of the energy recovery potential of turboshaft
separated (decoupled) electric turbocharger and its boosting capability in a spark-ignition engine
through simulation-based work and comparing it to a conventional turbocharged engine in terms
of fuel consumption. The main objective of this study is to evaluate the amount of energy that can
be recovered over a steady state full-load operating conditions and boosting capabilities from a
decoupled electric turbocharger of an SI engine using a 1-D engine simulation software. The
electric turbocharged system includes two motors and a battery pack to store the recovered
electrical energy. Gt-Power engine simulation software was used to model both engines and
utilizes each of the components described earlier. The conventional turbocharged engine is first
simulated to obtain its performance characteristics. An electric turbocharger is then modelled by
separating the turbine from the compressor. The turbine is connected to the generator and battery,
whereas the compressor is connected to the motor. This electrically turbocharged engine was
modelled at full load and controlled to produce the same brake power (kW) and brake torque (Nm)
properties as the similarly sized conventional turbocharged engine. This step was necessary to
investigate the effect an electrical turbocharger without a wastegate has on the engine’s BSFC and
determine the energy that can be recovered by the electrical boosting components, and cycle�averaged fuel consumption was evaluated. The evaluation of energy recovered from the electrically
turbocharged engine from the analysis can assessed in full-load steady state conditions that can
be useful for research in part-load and transient studies involving the decoupled electrical
turbocharger. The study revealed that a maximum of 21.6 kW of electrical power can be recovered
from the decoupled electrical turbocharger system, whereas 2.6% increase in fuel consumption
can be observed at 5000 rpm engine speed. |
