Question

Technician A says that the burning of the air-and-fuel mixture in the cylinder is called fuel activation. Technician B says that the basic function of the upper-end components is to control the flow of air-and-fuel mixture into the engine and the flow of the exhaust gases out of the engine after combustion. Who is right?

Answer 1

Both of the Technicians are correct.

Fuel activation in the cylinder needs air and fuel mixture which Technician A states. Also, Technician B explained that the upper-end component function is to regulate the air-and-fuel mixture together with the flow of exhaust gases that comes out after combustion. Each of them explained some engine parts which are connected and make a vehicle run.
