Supercharged internal combustion engine with two separate exhaust manifolds (2a,2b) from individual cylinder groups and two separate inlet manifolds (3a,3b) each leading to a respective cylinder group.

Supercharged internal combustion engine with two separate exhaust manifolds (2a,2b) from individual cylinder groups and two separate inlet manifolds (3a,3b) each leading to a respective cylinder group. An inlet conduit (9) from a supercharger (6) leads to an equalising chamber (11), from which two tuned resonance tubes (12,13) lead to the inlet manifolds. From the exhaust manifolds a pair of exhaust recirculation conduits (19a,21a,19b,21b), each containing a control valve (18a,18b) controlled by a control unit (16) for controlling the exhaust recirculation, lead to the inlet manifolds. The control unit is disposed to open the control valves when the exhaust pressure is higher than the pressure in the inlet manifolds.

The assembly of claim 3 wherein the shelf member further includes at least one brace member mounted to the lateral edge, extending perpendicular to one of the shelf surfaces and proximate the back edge and, wherein the first and second pins extend from the brace member. 5. The assembly of claim 4 wherein the first and second shelf surfaces are top and bottom surfaces, respectively, the top surface faces upward when the shelf member is mounted to the support member and the brace member extends from the bottom surface. 6. The assembly of claim 3 wherein the support member forms a plurality of slot delineators along a vertical length of the support member and adjacent slot delineators are equi-spaced along the vertical length. 7. The assembly of claim 3 wherein the slot delineators have essentially the same shape. 8. The assembly of claim 3 wherein the support member includes at least first and second essentially upright wall members that form an essentially right angle where the first wall member forms the receiving edge and the passageways extends into the second wall member, the first direction essentially perpendicular to the receiving edge. 9. The assembly of claim 8 wherein the first wall member includes first and second edges, the first and second wall members are linked at the first edge and the support member further includes at least a third wall member linked to the first wall member at the second edge, the third wall member extending from the first wall member in the first direction and opposing the second wall member. 10. The assembly of claim 9 wherein the third wall member forms an oppositely facing second coupler pair that is similar to the second coupler pair formed by the second wall member and that can be used to support a shelf member. 11. The assembly of claim 3 wherein, with the shelf member mounted to the support member, the shelf member extends from the support member in an extending direction and wherein the extending direction is opposite the first direction in which the passageway opens from the passageway opening to the distal end. 12. The assembly of claim 3 wherein, with the shelf member mounted to the support member, the shelf member extends from the support member in an extending direction and wherein the extending direction is the same as the first direction in which the passageway opens from the passageway opening to the distal end. 13. The assembly of claim 1 wherein the passageways are essentially identical and the recessed distal ends of the passageways are formed to receive the pins. 14. The assembly of claim 1 wherein the shelf member forms a second lateral edge opposite the first lateral edge and wherein the assembly further includes: a complimentary first coupler pair including complimentary first and second couplers mounted to the second lateral edge, the complementary first coupler pair couplers mounted such that the couplers are aligned along a complimentary coupler axis that is essentially perpendicular to the shelf surfaces and such that the complimentary coupler pair couplers are proximate the receiving edge; a complimentary support member opposite the at least one support member; a complimentary second coupler pair including complimentary third and fourth couplers linked to the complimentary support member, the complimentary third coupler positioned essentially directly above the complimentary fourth coupler; and one of the complimentary coupler pairs including complimentary first and second pins and the other of the complimentary coupler pairs including complimentary first and second slot delineators, the complimentary first and second pins forming complimentary first and second bearing surfaces, each complimentary delineator forming a complimentary passageway that opens in the first direction from the corresponding member's receiving edge and extends to a distal end, the distal ends of the complimentary first and second delineators recessing in th
