Description and operation
| 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. |
