What is the purpose of a purge valve?
In particular, the canister purge valve is an emissions control component that allows the engine intake vacuum to take the exact amount of fuel vapors from the EVA canister into the engine intake manifold. In newer model vehicles the purge valve is electrically operated solenoid controlled by the engine computer.
How does the purge valve in a car work?
The valve carries the responsibility to regulate the amount of fuel vapor emerging from the charcoal canister. The purge valve is known to work in synchronization with the charcoal canister to recycle the emissions as they need to get eliminated through the internal combustion process.
How does the vapor canister purge valve work?
The Evaporative Emission Control system features a vapor canister purge valve which manages the quantity of fuel vapor coming out of the charcoal canister. The purge valve used to be controlled with a vacuum but now, newer cars allow the engine control unit to electronically control it.
What happens when a bad purge valve is left unresolved?
If left unresolved, this will create even more severe issues. A faulty purge valve may by unable to redirect the fuel vapors into the engine’s cylinders for combustion. As a result, an unnecessarily rich fuel and air mixture will get combusted during each cycle of the engine.
How does the evaporative purge system work and how does it work?
Evaporative Purge System The evaporative purge system consists of a container and valve. A flap in the EVAP purge valve body restricts the motion of fluid and is magnetically attracted by the voltage applied via the valve’s electrical contacts.
How does the purge valve work in a car?
The purge valve used to be controlled with a vacuum but now, newer cars allow the engine control unit to electronically control it. The purge valve and charcoal canister work together to recycle the emissions back into the engine so that they’re eliminated as the internal combustion process takes place.
Evaporative Purge System The evaporative purge system consists of a container and valve. A flap in the EVAP purge valve body restricts the motion of fluid and is magnetically attracted by the voltage applied via the valve’s electrical contacts.
How does the flap in an EVAP purge valve work?
A flap in the EVAP purge valve body restricts the motion of fluid and is magnetically attracted by the voltage applied via the valve’s electrical contacts. The flap is attracted to a coil in the evaporative purge system, which closes the valve and blocks the passage of fluids.
What happens when you close the vapor canister purge valve?
This is the central computer of the vehicle which will calculate the exact amount of vapor that needs to go into the engine. Once it allows enough vapor through, the purge valve will close so that no mater vapor gets through. The vapor will just sit in the charcoal canister until it is needed again.
