This outlet feeds the engine intake manifold.

Turbocharged internal combustion engine with exhaust return via a valve (7) on the intake side (5) of the turbocompressor unit (2) to the engine intake side.

The nozzle may be attached to an engine intake and may be adapted to fit between a fuel injector and an engine without substantial modification to the engine.

The turbocharger includes a compressor with an outlet coupled to an intake of the engine and a turbine coupled to an exhaust manifold of the engine.

In one embodiment, the collected particles separate from the collecting structures and return to the engine intake.

The reformate may be passed to the inlet side of the engine, to improve overall efficiency of the engine, and/or may be mixed with exhaust gas before catalytic after treatment, to improve the control of emissions.

An arrangement for exhaust gas feedback in a combustion engine (1) with an ordinary first exhaust manifold (4), while a transfer line (8) is arranged between the engine's exhaust side and its inlet side.

The output from the reformer unit may be fed to the inlet side of the engine, and/or may be admixed with the remainder of the exhaust gases prior to catalytic aftrertreatment.
