Description

Emissions Control System consists of three major systems.

• The Crankcase Emission Control System prevents blow-by gas from releasing into the atmosphere.

  This system recycles gas back into the intake manifold (Closed Crankcase Ventilation Type).

• The Evaporative Emission Control System prevents evaporative gas from releasing into the
  atmosphere. This system burns gas at appropriate engine operating condition after gathering it in
  the canister.
• The Exhaust Emission Control System converts the three pollutants (hydrocarbons (HC), carbon
  monoxide (CO), and oxides of nitrogen (NOx)) into harmless substances by using the 3-way
  catalytic converter.
