Description
Evaporative
Emission
Control Valve
It is used to prevent gasoline
vapors from escaping into the
atmosphere from the fuel tank
and fuel system.
Storage the gasoline vapors to canister,
conduct the gasoline vapors to engine
by vacuum when starting the engine.
Canister
Storage the gasoline vapors
from fuel tank and fuel
system.
The gasoline vapors storage by
canister, to meet the regulation, the HC
emission con not exceeds 2 grams.
P.C.V
Recycle the fuel gas from the
crankcase blow by.
Recycle the fuel gas from the crankcase
blow by to the engine.
Oxygen Sensor
To control the air/fuel mixture
in best condition.
Sending the mixture condition info to
ECU by voltage signal, ECU controls
the fuel injection to meet the emission
regulation.
Catalyst
To reduce the emission of
HC, CO and NOx produced
from the exhaust gas.
Using the catalyst converts the HC and
CO to CO2 and H2O also reduce the
NOx pollution.
ECU
To control the injector, ignition
and bypass air of fuel
injection system to reach the
best driving condition.
ECU (Electric Control Unit), receiving
sensor which equipped on engine to
precisely control fuel injection and
ignition to reduce the exhaust emission
pollution.
3.1.
