Patent abstract
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.
