Evaporative Emission (EVAP) Ejector
WARNING: This page does not describe the selected car, but rather 31 other vehicles, including the 2016 Lincoln Navigator, 2016 Lincoln MKZ, 2016 Lincoln MKX, 2016 Lincoln MKT, and 2016 Lincoln MKS. However, it is still accessible from the selected car via links, so may be relevant.
The EVAP ejector is used on turbocharged engines to create a vacuum in the EVAP purge line from the EVAP purge valve to the intake air system. During boost conditions, boost pressure flows through a venturi inside the EVAP ejector creating a vacuum in the EVAP purge line to the intake air inlet to the turbocharger. When the second EVAP check valve is open, the purge vapor is drawn through the EVAP ejector into the intake air tube, through the turbocharger and charge air cooler, to the intake manifold.
