The system that is MOST-Likely used to prevent the emission of hydrocarbons in blowby gases from the crankcase by scavenging them from the crankcase and reintroducing them into the combustion chambers is:
A)PCV system
B)PVC system
C)EGR system
D)CVS system

Question

Quizplus · Accepted Answer

The PCV (Positive Crankcase Ventilation) system is designed to prevent hydrocarbon emissions from the crankcase by scavenging them and reintroducing them into the combustion chambers. The system operates by drawing the blowby gases from the crankcase through a tube and into the intake manifold, where they are burned off during normal combustion. This system is effective at reducing emissions and improving overall engine performance. The PVC system and CVS system are not commonly used in this application, and the EGR system is used to reduce NOx emissions by recirculating exhaust gases back into the combustion chamber, not hydrocarbons from the crankcase.
