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 exceed
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 control 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 convert the
HC and CO to oxygen and
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.
Trouble Shooting
Low engine power, instable engine idle speed
Clog in canister or tubes.
Emission control valve malfunction.
E.E.C. system tubes loosen or crack.
ECU malfunction.
Engine idle speed and acceleration in bad condition
Clog in canister or tubes.
Emission control valve malfunction.
