Way to Determine the Failed EGR Valve of the Car

Way to Determine the Failed EGR Valve of the Car
2
Exhaust gas recirculation(EGR) valve is a part of
the emission system which is designed to
recirculate the exhaust gases into the car's
intake for reducing cylinder temperature.
3
It is the important components of the car that
can control the flow and recirculations of the
exhaust gases.
4
When the valve of the car is opened, then the
exhaust gases flow through the car's EGR system
to control the car emission.
5
But the issues in the EGR valve can occur many
problems in the flow and operation of the EGR
system and reduce the performance as well as
increase the emission.
6
The failed EGR valve can produce the following
signs in your car to alert the drivers about
these potential issues.
7
Rough idle of the engine
8
The rough idle is the most common warning sign of
a malfunctioned EGR valve and stuck in the open
position of the car.
9
In this way it can lead to the exhaust gas
recirculations and cause rough idling as well as
fuel smell in the car.
10
Illuminated check engine light
11
The check engine of the car is illuminated for a
wide variety of issues and the failed or damaged
EGR valve is another reason.
12
When your car computer detects any issues in the
EGR valve circuit or position, then it
illuminates the check engine light to notify the
driver regarding the issue.
13
Reduce the engine performance
14
The most common sign of a failed EGR valve in
your car is the reduction of engine performance
and makes the car stall or hesitate while
accelerating.
15
The clogged or malfunctioned EGR valve of the car
interrupt the car's air-fuel ratio and cause
engine performance issues like reduction in power
and fuel efficiency.
16
Unusual sound during acceleration
17
If you hear an unusual sound like pinging or
knocking while accelerating the car, then it
proves that the fuel is detonating within the
engine instead of burning steadily.
18
The damaged EGR valve of the car does not allow
the right amount of exhaust to dilute the
air-fuel mixture and lower the combustion chamber
temperature.
19
Conclusion
20
The EGR valve is an important component of the
emission system in the car to prevent the
emissions produced from the car.
21
With a well functioned EGR valve, you can easily
pass the smog test of your car. When you found
issues in the EGR valve of the car, inspect it by
a professional mechanic.
