Question

Technician A says that valve springs close the valves. Technician B says that turbulence in the combustion area creates a better burn of the air fuel mixture who is correct?

A. A only
B. B only
C. Both A and B
D. Neither A nor B

Answer 1

Both Technician A, who says valve springs close the valves, and Technician B, who says that turbulence in the combustion area creates a better burn of the air-fuel mixture, are correct.

Step-by-step explanation:

In regard to the schoolwork question presented, we are looking at the functions of an internal combustion engine and the roles different components play in the operation and efficiency of the engine. We have two statements from Technician A and Technician B to evaluate:

• Technician A states that valve springs close the valves. This is a correct statement. Valve springs are a critical component of the engine's valve train, and they are responsible for returning the valves to their closed position after they have been opened by the camshaft.
• Technician B says that turbulence in the combustion area creates a better burn of the air-fuel mixture. The statement is technically correct; good turbulence ensures more uniform mixing of the air and fuel, leading to more efficient combustion.

Therefore, the correct answer to the question is C. Both A and B are correct.
