Abstract

The turbocompressor for supercharging an internal combustion engine comprises a compressor whose output is connected to the intake manifold of the engine driven by a turbine which is driven by the exhaust gases of the engine. A take-off duct brings a fraction of the airflow supplied by the compressor to the exhaust gases upstream of the turbine. The turbine comprises distributor vanes with variable setting, typically in a range of about 40.degree.. With this arrangement, the low speed running torque and the efficiency are improved, more especially in the case of traction engines.
