ExHAUST SySTEM
The exhaust system is made up of the engine exhaust manifold, a turbocharger, an exhaust pipe, a
muffler, and a tail pipe. Hot exhaust gases from the exhaust manifold are directed to the turbocharger.
The pressurized exhaust gases rotate a turbine wheel at one end of a turbine shaft in the turbocharger.
This rotational force is transmitted to another turbine wheel at the other end of the turbine shaft, which
compresses intake air going to the cylinders for more efficient combustion. For service information and
a more detailed description of the engine turbocharger, refer to the appropriate section of the engine
manufacturer’s service manual furnished with the coach.
Maintenance
All joints and clamps in the exhaust system should be routinely and
regularly inspected for tightness and integrity. The leaking of exhaust
gases into the passenger area can be dangerous and life-threatening.
The exhaust system should be inspected periodically for restrictions and leaks. Kinks or crimped pipes
can result in excessive back pressure which can cause increased fuel consumption, power loss, and pos-
sible damage to the combustion chamber components. Exhaust leaks are commonly the result of loose
clamp bolts, corroded pipes, or a punctured muffler. Damaged components should be repaired or re -
placed immediately.
