Basic Exhaust System

Basic Exhaust System Points : Basic Exhaust System of car An exhaust system quiets engine operation and carries exhaust fumes to the rear of the vehicle. The parts of a typical exhaust system are shown. They include: 1. EXHAUST MANIFOLD (connects cylinder head exhaust ports to header pipe). 2. HEADER PIPE (steel tubing that carries exhaust gases from exhaust manifold to catalytic converter or muffler). 3. Catalytic Converter (device for removing pollutants from engine exhaust). 4. INTERMEDIATE PIPE (tubing sometimes used between header pipe and muffler or catalytic converter and muffler). 5. MUFFLER (metal chamber for damping-pressure pulsations to reduce exhaust noise). 6. TAILPIPE (tubing that carries exhaust from muffle); to rear of car body). 7. HANGERS (devices for securing exhaust system to underside of car body). 8. HEAT SHIELDS (metal plates that prevent exhaust heat from transferring into another object). 9. MUFFLER CLAMPS (U-bolts for connecting: pails of exhaust system together). 2ndSubContent When an engine is running, extremely hot gases blow out of the cylinder head exhaust ports. The gases enter the exhaust manifold. They flow through the header pipe, catalytic converter, intermediate pipes muffler, and out the tailpipe.
