Question 1

26.20.2 Describe the function of the exhaust manifold.

Answer 1

The function of the exhaust manifold is to collect the products of combustion from each cylinder and discharge them into the air stream.

Question 2

26.20.4 Explain the importance of proper sealing of the exhaust manifold.

Answer 2

A leaking exhaust manifold presents a fire hazard, and can lead to toxic gasses entering the cockpit
(CO-carbon monoxide).

Question 3

26.20.6 Describe the possible sources, indications and associated danger of carbon monoxide gas.

Answer 3

A leaking/unsealed exhaust manifold can lead to carbon monoxide entering the cockpit. Another source is via cabin vents whilst using cabin heat. This is particularly dangerous because carbon monoxide is a colorless and odorless poisonous gas.
