Abstract: An improved turbocompound system, in particular in the field of industrial vehicles. A first turbine drives a fresh air compressor. A power turbine is arranged downstream of the first turbine and operatively coupled with the crankshaft of the engine through a clutch. A first electric motor/generator is operatively coupled with the turbocharger system. A second electric motor/generator is operatively coupled with the power turbine. The first and second electric motor/generators are electrically interconnected, and controlled as a motor or a generator in an opposite way with respect to each other, so that the electric energy produced by one is consumed by the other and vice versa.
