Abstract
Abstract The invention relates to an arrangement pertaining to internal combustion engines ( 1 ) that include a supercharger ( 6 ) and an intermediate cooler ( 13 ) mounted in a casing ( 4 ). The intermediate cooler includes tubular elements ( 14, 15 ) through which coolant flows for cooling the combustion air compressed by the supercharger ( 6 ). Conventional arrangements of this kind take up a significant amount of space, which is difficult to find in a typically crowded engine space, and also result in undesirable heating of the engine space. A significant improvement has been achieved in these respects by means of the present invention, which is characterized in that the tubular elements ( 14, 15 ) are housed in a cylindrical housing ( 16, 17 ) which includes longitudinally extending slots ( 20, 21 ) and which forms in the casing ( 4 ) a partition wall which is broken by said slots ( 20, 21 ) through which the compressed combustion air is intended to pass into and out from the spaces between the tubular elements ( 14, 15 ) and the housing.

Claim 1
Independent Claim
276 words
An arrangement pertaining to an internal combustion engine ( 1 ) that includes a supercharger ( 6 ) for compression of combustion air delivered to said engine, and a cooling means ( 13 ) for cooling the compressed combustion air by means of a heat exchanger that includes tubular elements ( 14 , 15 ) through which a coolant flows and which are contacted externally by the compressed combustion air, wherein engine cylinder induction ports ( 2 ) are connected directly to outlet openings ( 3 ) allocated to respective induction ports, wherein said outlet openings ( 3 ) are formed in a casing ( 4 ) which communicates with the supercharger ( 6 ) and which forms a distribution chamber ( 5 ) for the compressed combustion air and in which the tubular elements ( 14 , 15 ) in said heat exchanger are mounted in front of at least the major part of the outlet openings ( 3 ), wherewith the compressed combustion air flows transversely to the outlet openings ( 3 ), characterised in that the tubular elements ( 14 , 15 ) of the heat exchanger are housed in a cylindrical housing ( 16 , 17 ) that includes longitudinally extending slots ( 20 , 21 ) and that forms integral with said casing a partition wall which is broken solely by the slots ( 20 , 21 ) through which the compressed combustion air is intended to pass into the spaces between the tubular elements ( 14 , 15 ) and the housing and out through said spaces in a direction towards the outlet openings ( 3 ) in said casing.
