<p>An EGR apparatus for a CI engine (4) which includes an EGR pipe (20) which joins the exhaust pipe (16) of the engine (4), at a point located downstream from a post-treatment device (14), to the pipe located upstream from the supercharger compressor (10), an EGR cooler (23) and an EGR compressor (24) for positive displacement through the EGR pipe (20). The EGR compressor (24) is activated by means of an electric motor (25) which is controlled by a control module (26) based on a model responding to an EGR flow demand depending on the operative parameters of the CI engine (4).</p> |
