Patent abstract
Methods and systems are provided for a fuel system in a hybrid vehicle. In one example, a method includes activating a fuel pump in a fuel tank included in the hybrid vehicle responsive to a refueling event with a level of residual fuel higher than a fill threshold. By activating the fuel pump, residual fuel in the fuel tank is mixed with newly received fuel in the refueling event enabling improved combustion in a subsequent engine-on condition.
