Emission Control System: Purpose
The emission control systems are installed to reduce the amount of HC, CO and NOx exhausted from the engine ((3) and (4)), to prevent the atmospheric release of blow-by gas-containing HC (1) and evaporated fuel containing HC being released from the fuel tank (2). The function of each system is shown in SYSTEM FUNCTION :
SYSTEM FUNCTION
| System | Abbreviation | Function | ||
|---|---|---|---|---|
| Positive Crankcase Ventilation | PCV | Reduces HC | ||
| Evaporative Emission Control | EVAP | Reduces evaporated HC | ||
| Three-Way Catalytic Converter | TWC | Reduces HC, CO and NOx | ||
| Sequential Multiport Fuel Injection (1) | SFI | Injects a precisely timed, optimum amount of fuel for reduced exhaust emissions | ||
