Abstract
The invention concerns an exhaust silencer arrangement with a transverse exhaust silencer in a four-chamber type of construction, in particular for very small passenger-transporting motor vehicles, with a 3-cylinder rear-mounted engine and an exhaust gas turbocharger. The silencer comprises a housing which is composed of two half shells and accommodates a catalyst module in an integrated manner. The catalyst module, which does not have its own housing, forms a silencer system partition which divides the silencer into a 3-pot main chamber and an additional chamber which is in particular a resonator chamber and communicates with the main chamber via connection ducts formed in the half-shell housing.
Claims29
An exhaust muffler arrangement comprising:
- a housing;
- a catalytic converter module positioned in said housing, said converter module dividing an interior of said housing into a main chamber and an auxiliary chamber formed as a resonance chamber, said housing defining a cross section of said main chamber and said resonance chamber, said catalytic converter having a cross section substantially equal to said cross section of one of said main chamber and said resonance chamber;
- a connection channel integrated in said housing and connecting said main chamber and said resonance chamber, said main chamber and said resonance chamber communicating through said connection channel.
An exhaust muffler arrangement comprising:
- a housing;
- a catalytic converter module positioned in said housing, said converter module dividing an interior of said housing into a main chamber and an auxiliary chamber formed as a resonance chamber, said catalytic converter module having an oblique inlet funnel on one side of said auxiliary chamber, said catalytic converter module having an outlet flow side on one side of said main chamber;
- a connection channel integrated in said housing and connecting said main chamber and said resonance chamber, said main chamber and said resonance chamber communicating through said connection channel.
An exhaust muffler arrangement comprising:
- a housing;
- a catalytic converter module positioned in said housing, said converter module dividing an interior of said housing into a main chamber and an auxiliary chamber formed as a resonance chamber, said main chamber has a substantially constant cross section and is divided by first and second intermediate walls located at spaced locations from one another, said intermediate walls divide said main chamber into first, second and third individual chambers, said first individual chamber extends between said catalytic converter module and said first intermediate wall in an axial direction of said main chamber, said second individual chamber extends between said first intermediate wall and said second intermediate wall, and said third individual chamber extends between said second intermediate wall and an end of said housing;
- a connection channel integrated in said housing and connecting said main chamber and said resonance chamber, said main chamber and said resonance chamber communicating through said connection channel.
