General
Exhaust system of Bristell B23-915 airplane consists of exhaust pipes
(1) from the four cylinders leading the exhaust gases to the
turbocharger (3), where a part of the exhaust gas energy is transferred
to the air inlet system by compressing (and heating) the engine air.
Connected to this exhaust manifold is the muffler (4), working at the
same time as a silencer. Exhaust gases lead from there by the exhaust
end pipe (6) down the airplane.
Mounted on the muffler is heat exchanger from which is taken warm
air for the heating system of the cockpit (see chapter 21-40)
The whole exhaust system is a stainless steel welded design and part
of the certified engine.
