That innovation which is achieved when innovators overlap layers of meaning in terms of its interpretation and creativity within a given context. With that in mind, a few days ago I read an article on the characteristics of independent artists (http://www.revistaarcadia.com/impresa/especial/articulo/el-momento-indep...
A canister purge valve is a solenoid valve controlled by the Power Train Control Module. The Power Train Control Module is a control unit that determines the ignition timing, fuel amounts and other parameters needed to keep the engine running.
There are three chambers inside the canister, running in sequence from the intake to the outtake. The interior of the canister is filled with charcoal or carbon pellets. The input of the canister connects to the gas tank's vent port, while the output connects to the purge valve in the side of the vehicle's intake manifold. When the vehicle is shut off, there is a pressure imbalance within the fuel tank caused by fuel being siphoned out, but no air being let back in to take up the empty space.
