(54) EXHAUST SYSTEM OF INTERNAL COMBUSTION ENGINE

 . /

Ticking refers to exhaust systems of internal combustion engines, primarily motorcycle engines. .

Known exhaust system of internal combustion engines, containing the exhaust channel of the cylinder, connected to it and concentrically located inner and outer pipe and exhaust pipes and a silencer 11.

However, such an exhaust system for motorcycle engines is very time consuming to manufacture complex installation on a motorcycle without disturbing the external shape of the latter.

The purpose of the invention is to reduce the toxicity of exhaust gases of a motorcycle engine while at the same time simplifying the design and exhaust system.

To achieve this goal, an additional insert is installed in the outlet channel of the cylinder, equal in diameter to the internal outflow pipe.

The drawing shows the superior sistem.t motorcycle engine, cut.

The exhaust system contains a standard external exhaust pipe 1, an internal pipe 2 and an additional insert 3, equal in diameter to the internal pipe 2. Insert 3 is installed with a gap in the inlet channel of cylinder 4 and does not reach the external window of the latter to ensure the exhaust gas flows as in the internal insert 3 and pipe 2, and in the annular gap. The insert 3 is fixed at the place of attachment of the exhaust pipe 1 to the cylinder 4 by a nut 5. The pipe 2 is concentrically located inside the exhaust pipe 1 along its entire length up to the entrance to the muffler

6and firmly secured with pins

7 and 8 located at the pipe ends radially and in mutually perpendicular planes. Pins 7 and 8 are welded to LOW pipe 1. Internal pipe 2 and insert 3 can be made of heat-resistant stainless steel with the lowest possible. thick walls. Exhaust gases leaving cylinder 4 move both inside the insert 3 and the inside pipe 2, and along the annular {gap between the walls of the exhaust channel of the cylinder 4 and insert 3, as well as between the pipes

Claims (1)

Claim The exhaust system of an internal combustion engine, mainly a motorcycle, containing _{5 the} exhaust channel of the cylinder, connected to it and concentrically located internal and external exhaust pipes and a silencer, characterized in that, in order to reduce the toxicity of refract ₍₀ working gases, in the exhaust channel of the cylinder an additional insert is installed, equal in diameter to the inner exhaust pipe.
