Simulation of exhaust waste energy recovery potentials using electric turbo compound in a turbocharged gasoline engine

Thermal efficiency of a spark-ignited engine is normally in the range of 25 % to 35% and reciprocating engines represent a very large source of waste heat with most of the losses are from the exhaust, through coolant, by direct convection and radiation to the environment. There is a significant pote...
