Abstract
Official abstract text for this publication.
Methods and systems are provided for conducting an evaporative emissions test on a fuel tank and an evaporative emissions system in a vehicle. In one example, pressure for the evaporative emissions test is provided by inductive heating of the fuel tank while the vehicle undergoes an inductive battery charging operation. In this way, evaporative emissions testing may be enabled under conditions wherein sufficient heat rejection from the engine to the fuel tank is not available, and further enables evaporative emissions testing without the use of an external pump thus eliminating additional costs, and reducing the space occupied in the vehicle for evaporative emissions testing diagnostics.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method comprising: charging a battery of a hybrid electric vehicle by coupling a magnetic field between a primary coil external to the vehicle and a secondary coil onboard the vehicle; coupling the magnetic field between the primary coil and a fuel tank, the fuel tank being a ferrous fuel tank or a ferrous member being coupled to the fuel tank; comparing pressure in a fuel system and/or an emission system coupled to the fuel tank to a reference p…
