Engine Emission Control (Description and Operation)

~1min read

CAUTION: Do not remove any part of the engine emission control system. Operating the engine without the engine emission control system will reduce fuel economy and engine ventilation. This will weaken engine performance and shorten engine life.

The engine emission control consists of the:

  • positive crankcase ventilation (PCV) system.
  • exhaust gas recirculation (EGR) system.
