Definitions

  • the invention relates to an exhaust system of a multi-cylinder reciprocating piston engine with two rows of cylinders according to the preamble of claim 1.
  • the characterizing features of claim 1 serve. If the exhaust gases of the two rows of cylinders flow through a front silencer lying transversely to them in countercurrent, a short overall length of the exhaust system and the engine can be achieved by appropriate arrangement behind the engine. A spatially compact construction is further favored by the fact that the catalytic converters and main silencers lie alongside the rows of cylinders. Such an exhaust system is ideally suited for a V-engine, which is arranged in the rear of the vehicle. But it also has spatial advantages for a mid-engine.
  • the silencer in coordination with the total stroke volume of the cylinders, an exhaust system with low pressure loss and good damping can be created despite multiple deflection of the exhaust gas flows.
  • both exhaust pipes in the central region 12 are separated into two sections 10 ', 10' 'and 11', 11 ''.
  • the sections are bent at the ends and provided with nozzle-shaped end pieces and arranged with respect to one another such that the exhaust gases run against one another in cross-counterflow.
  • the exhaust gases After exiting the front silencer 7, the exhaust gases enter the main silencers 14, 15 lying parallel to the rows of cylinders. They enter the main silencers from the rear, turn 180 ° on the front and enter the tailpipes 16 leading to the outside again at the rear. 17 out.
  • the entire exhaust system is constructed symmetrically to the central longitudinal axis 18 of the engine.
  • the right and left catalytic converters and main silencers are each of the same size and are equidistant from the central longitudinal axis 18.
  • the exhaust gases from one row of cylinders flow through the main silencer adjacent to the other row of cylinders. In order to keep the flow resistance low despite the multiple sharp deflections, the volumes of the casing pipes surrounding the silencers and catalytic converters are quite large.
  • the ratio of the total catalyst volume V Kat to the total stroke volume of the cylinders V H is 1.4; the ratio of the total damping volume V D to the total stroke volume V H is 14.
  • the large-volume main silencers are below the two rows of cylinders arranged so that the installation length of the motor does not have to be increased because of them.
  • the engine with the exhaust system is mounted centrally on an engine mount 19 of the motor vehicle.
  • the motor mount 19 is integrated in the axle structure (subframe) of the motor vehicle.
