Technician A says the EVAP system assists in the reduction of oxides of nitrogen (NOx). Technician B says the EVAP system prevents fuel vapors from escaping into the atmosphere. Who is correct?

A. Technician A
B. Technician B
C. Both technicians
D. Neither technician

Answer :

Final answer:

Technician B is correct; the EVAP system prevents fuel vapors from escaping into the atmosphere. Technician A is incorrect as the reduction of NOx is managed by the catalytic converter, not the EVAP system.

Explanation:

In response to the question regarding the EVAP (Evaporative Emission Control) system, Technician B is correct. The primary function of the EVAP system is to prevent fuel vapors from escaping into the atmosphere. These fuel vapors contribute to air pollution and smog formation if released uncontrolled. Therefore, the EVAP system is fundamental in reducing emissions of volatile hydrocarbons into the environment. On the other hand, the reduction of oxides of nitrogen (NOx) is not the function of the EVAP system but is instead handled by devices like the catalytic converter, which catalyzes reactions that convert NOx to nitrogen gas (N₂) and other less harmful products.

In summary, Technician B's statement about the EVAP system's role in preventing fuel vapor release into the atmosphere is correct, while Technician A's assertion that it assists in the reduction of oxides of nitrogen is incorrect.

The correct answer to the student's question is (option B) Tech B.
