Abstract
An exhaust cleaning system for motor vehicles, especially a diesel exhaust cleaning system for medium to heavy utility vehicles. The exhaust cleaning system has an exhaust muffler (1), a catalytic converter (2) and an exhaust particle filter element (3). The exhaust muffler (1), the catalytic converter (2) with a U-shaped tubular urea injection element (4) arranged upstream and an exhaust particle filter element (3) are integrated in a common housing and designed as a structural, functional unit.
Claims19
An exhaust cleaning system for motor vehicles, comprising:
- an exhaust muffler, a catalytic converter and an exhaust gas particle filter element integrated in a common housing and forming a structural and functional wilt;
- a U-shaped tubular urea injection element, wherein said exhaust muffler has multiple chambers and wherein said catalytic converter is a selective catalytic reduction (SCR) catalytic converter for the selective catalytic reduction of the harmful substances present in the exhaust gas, said SCR catalytic converter said particle filter element and said U-shaped tubular urea injection element extending in said housing in an axial direction essentially in parallel to one another and extending into multiple chambers.
An exhaust cleaning system comprising:
- a housing having an inlet and outlet;
- an exhaust muffler arranged in said housing;
- a catalytic converter arranged in said housing;
- an exhaust gas particle filter element arranged in said housing, said particle filter and said catalytic converter being formed as separate structures in said housing, said muffler, said catalytic converter and said particle filter being in communication with said inlet and said outlet of said housing;
- said housing includes a jacket radially surrounding said muffler, said catalytic converter and said particle filter;
- said catalytic converter and said particle lifter are arranged axially overlapping in said jacket of said housing.
