C) Thermostatic air cleaner
D) EGR valve

Question

Quizplus · Accepted Answer

The AIR pump (Air Injection Reactor) sends fresh air to the catalytic converter to help oxidize emissions. This process helps reduce harmful emissions from the engine. The PCV valve (Positive Crankcase Ventilation) is responsible for recycling the air that is in the engine's crankcase back into the intake manifold to be burned again, helping to reduce harmful emissions. The thermostatic air cleaner is responsible for controlling the temperature of the air entering the engine to improve fuel efficiency and performance, but it does not have a direct impact on emissions control. The EGR valve (Exhaust Gas Recirculation) recirculates a small amount of exhaust gas back into the engine to reduce the formation of harmful pollutants, but it does not specifically send fresh air to the catalytic converter.
