Abstract
The present invention relates to an apparatus for recirculation of exhaust gases in a supercharged combustion engine. The apparatus incorporates an inlet duct (6, 6') for supply of a composite medium comprising a mixture of air and exhaust gases to the combustion engine (1). Mixing exhaust gases with the air reduces the combustion temperature and hence the content of nitrogen dioxides in the exhaust gases. The inlet duct (6, 6') incorporates a venturi (11) to allow the addition of exhaust gases to the pressurised air in the inlet duct (6, 6'). The apparatus incorporates flow guide means (13a-d) which are designed to create a static pressure distribution (Ps) adjacent to the venturi (11) such as to counteract growth of the boundary layer of flowing medium in an expanding third portion (11c) of the venturi (11). This means that the final inlet duct (6') situated after the venturi (11) can be made relatively short so that the apparatus may be of compact design.
