A turbocharging system includes a low pressure turbocharger (41) and a high pressure turbocharger (42); a cut-off valve (61) that cuts off communication between the outlet of a turbine of the high pressure turbocharger and the inlet of a turbine of the low...

Each exhaust gas outlet manifold (8, 10) is connected to its own exhaust gas turbocharger (12, 16), upstream of the common exhaust pipe (24). The turbocharger turbine wheels (12a, 16a) are driven via variable valves, as a function of engine loading and spe...

The present invention provide a feedback combined system of a reciprocating internal combustion engine, in which, in order to increase output and thermal efficiency by increasing fuel supply without increasing the maximum combustion temperature than the co...

An internal combustion engine, particularly suitable for a motor vehicle, is provided with a plurality of combustion cylinders, at least a first exhaust manifold and a second exhaust manifold and at least one intake manifold. Each exhaust manifold is coupl...
