Abstract

An internal combustion engine is disclosed including at least two cylinders, each including an inlet port, an air inlet manifold for providing air to the cylinders, at least two outlets for emitting exhaust gases from the cylinders, a recirculation conduit for reducing harmful emissions from the exhaust gases and extending from one of the outlet for recirculating the exhaust gases from an outlet to a connection point in the air inlet manifold thereby defining a first volume from the outlet to the connection point, the air inlet manifold being divided into at least two further volumes defined by the distance between the connection point to each of the inlet points, at least one turbine for recovering energy from the exhaust gases, and a compressor for compressing air supplied to the air inlet manifold, the first volume and the further volumes being dimensioned such that the recirculated exhaust gases are substantially equally distributed between each of the cylinders.
