Description and operation
| Description |
Emissions control system consists of the three major systems.
| • |
Crankcase emission control system prevents blow-by gas from going into the atmosphere. This system burns these gases after moving them to the intake manifold (Closed Crankcase Ventilation Type). |
| • |
Evaporative emission control system prevents evaporative gas going into the atmosphere. This system burns the gases at appropriate engine operating condition after gathering it in the canister. |
| • |
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. |
