Definitions
- the invention relates to an exhaust system for an internal combustion engine having a first, a flow-through first silencer, in particular rear silencer, comprehensive exhaust system and at least one parallel to this second, a second silencer, in particular rear silencer comprehensive exhaust system, wherein the first silencer and the second silencer a have different structure.
- Such exhaust systems are used in series in particular in motor vehicles in order to influence the sound emission of the internal combustion engine.
- DE 197 43 446 A1 describes an exhaust system for an internal combustion engine, which ensures a good sound attenuation over the entire frequency range in view of a reduced noise level of motor vehicle engines and yet does not allow the exhaust pressure to rise too high even at high engine speed.
- two parallel mufflers are provided, which are tuned to different frequencies. Both mufflers are on the one hand as flowed through
- the exhaust system described with DE 197 43 446 A1 comprises an exhaust system, which is formed in sections in parallel. According to the embodiments, the exhaust gas flow is supplied to the two mufflers on the input side via a common, forking exhaust pipe and / or merged on the output side and discharged via a common exhaust pipe, respectively, a doppelgabelförmiges crosspiece is provided as a cross-talk.
- the typical sound of an internal combustion engine having at least two rows of cylinders, such as V8, is lost.
- the vibrations of odd orders are lost, it dominates the ignition order (4th order of the vibrations) and their harmonics. Attributes such as strength and strength can only be represented by volume, so that in this respect there is a conflict with the demand for comfort which is placed on the drive.
- the crankshaft of multi-cylinder internal combustion engines is created by juxtaposing the crankcases of the individual cylinders.
- the changing cylinder pressures which act on the exhaust system via the outer elegantschalleitweg depending on Kröpfungs merge and firing order, have a significant share of the characteristic engine noise.
- a common firing order is 1-5-4-8-6-3-7-2 with cylinders 1-4 associated with one cylinder bank and cylinders 5-8 with the other cylinder bank.
- the object of the invention is to provide an aforementioned exhaust system, by means of which without excessive volume and thus a high level of comfort sufficient, the typical powerful and strong sound of an internal combustion engine with multiple cylinder banks, such as a V8 internal combustion engine, can be displayed. In particular, the significant frequency components in the oscillations of odd orders should be preserved.
- the first muffler comprises an input and an output tube, wherein the output tube has a small length and the second muffler comprises an input and an output tube, wherein the output tube has a long length.
- Short length and “long length” refers primarily to the ratio of the lengths to each other, with one length being significantly larger than the other.
- the decisive factor here is the acoustically effective length, which is determined by the exhaust gas inlet and outlet location.
- the output tube of the first silencer has at least approximately twice the length of the output tube of the second silencer.
- the output tube of the second silencer has an at least slightly larger diameter than the output tube of the first silencer, so that backpressure differences due to the longer output tube are avoided.
- the inlet pipe of the first silencer expediently opens into the input side first subspace.
- the output tube passes through the second and third subspaces, wherein the output tube is fluidizable both from the first subspace and from the first subspace through the second subspace.
- the second silencer has an inner structure which is subdivided into three subspaces by means of two partitions, wherein the first parting plate is sealed and the second parting plate is perforated. Between the second and the third subspace a gas exchange via the partition is possible, the partition to the first subspace is tightly closed.
- the inlet pipe of the second silencer expediently passes through the first and second Input side subspace and opens into the third subspace.
- the starting tube leads through the second subspace into the first input side subspace and arcuately curved back through the second subspace and the third subspace, whereby the output tube can be flow-charged on the input side both from the third subspace and from the third subspace through the second subspace.
- the use of a resonator which connects the third subspace to the first subspace has proven to be very advantageous.
- FIG. 1 shows a twin-flow exhaust system for a V8 internal combustion engine with rear silencer
- Figure 2 shows a first rear muffler with a short output tube
- FIG. 3 shows a second rear silencer with a long outlet pipe.
- FIG. 1 shows a twin-flow exhaust system 100 with a first exhaust gas line 102 and a second exhaust gas line 104 for a V8 internal combustion engine (not shown here).
- the internal combustion engine comprises two rows of four cylinders each, wherein a first cylinder bank with the cylinders one to four and a second cylinder bank with the cylinders five to eight are formed.
- ignition takes place in the order 1-5-4-8-6-3-7-2.
- the outlets of the first cylinder bank open into the manifold 106 of the first exhaust line 102, the outlets of the second cylinder bank open into the manifold 108 of the second Exhaust line 104.
- each exhaust gas train 102, 104 comprises pre-silencers 114, 116 and middle silencer 118 and rear silencers 124, 126 configured as absorption dampers.
- the exhaust system 100 is completely twin-flow, designed essentially without crosstalk.
- a minimal cross-talk location is provided in the area of the center silencer 118, wherein an internal separation occurs within the common center silencer 118.
- the front portion of the center muffler 118 is assigned to the one exhaust line, the rear area to the other.
- the rear mufflers 124, 126 of the exhaust system 100 are constructed differently from the otherwise symmetrical structure of the exhaust system 100 with the goal by changing the phase relationship of the individual mouths amplification of the vibrations odd To achieve orders in the far field outside and inside noise. Details of the rear mufflers 124, 126 are shown and described with FIGS. 2 and 3.
- the rear muffler 120 of the first exhaust line 102 is shown in Figure 2 in two views and designated 200.
- the rear silencer 200 is pot-shaped from two mutually tightly connected half shells 202 and 204 formed, which enclose an interior.
- the interior is divided by a perforated partition 206 and a dense partition 208 into three compartments 210, 212 and 214, wherein the compartment 212 is filled with an absorbent material 228.
- the input tube 216 opens into the first subspace 210, it is followed by a resonator 226 extending through the second subspace 212 into the third subspace 214.
- the exit tube 224 extends from the first subspace 210 through the second subspace 212 and the third subspace 214
- Rear muffler 200 is carried out starting from the inlet pipe 216, which opens via holes 218 in the first subspace 210 via holes 220 in the output tube 224 on the one hand and through the perforated partition 206 and the second subspace 212 via holes 222 in the output tube 224 on the other.
- the rear muffler 122 of the second exhaust line 104 is shown in Figure 3 in two views and designated 300.
- the rear silencer 300 is pot-shaped from two mutually tightly connected half-shells 302 and 304 formed, which enclose an interior.
