摘要： An engine-turbocharger unit for a vehicle, in particular an industrial vehicle, having an internal combustion engine; a decompression brake device; and a turbocharger in turn having a variable-geometry turbine driven by the exhaust gas from the engine, and a compressor driven by the turbine and connected at the outlet to an intake manifold of the engine; the unit also has a throttling device located on the outlet side of the turbine and settable between a fully-open attitude and a closed attitude; the variable-geometry turbine and the throttling device are jointly controlled, thereby allowing independent control of the exhaust manifold pressure of the combustion engine and of the expansion ratio of the turbine.
