ABSTRACT:
Exhaust device wherein the exhaust gas from the engine is not directly exhausted to the ambient air. The free end of the exhaust pipe is closed and openings are arranged in the mantle of the pipe in the area of the free end. The openings are directed to the road side. Openings are also provided in the exhaust pipe within the housing of the exhaust device. Additional filters are mounted in the container to purify the exhaust gas. The container is provided with an inner wall or coating along the mantle surface to improve sound damping. The simple construction of the proposed exhaust device makes its manufacture inexpensive. Furthermore, its contribution to the protection of the environment is considerable.
