5. What does the Carburettor Heat make and whats its Effect?

5 When caburator is very cold, i.e. when flying in high altitude and plane is descending through moist air the carburator intake will suffer from icing.
Carburator heating prevents parts of carburator being coated with ice and therfore prevents malfunction of mixture being provided.

4 Engine compressor provides compressed air to the engines intake. This way more oxygen is delivered into the cylinder. More gasoline can be used to mix explosive gas. More power can be produced. Especially interesting with thinner air at higher altitudes
