  • Method for detecting a sticking tank vent valve
    Patent number: 10166862
    Abstract: A method for detecting a sticking tank vent valve in a motor vehicle, a temperature sensor being situated in a tank vent line between the tank vent valve and an inlet point into an intake manifold or into a turbocharger and sticking of the tank vent valve being detected when the absolute value of a correlation of a calculated tank ventilation mass flow and of a signal value of the temperature sensor violates a predefinable threshold value.
    Type: Grant
    Filed: July 4, 2016
    Date of Patent: January 1, 2019
    Assignee: ROBERT BOSCH GMBH

  • METHOD FOR ASCERTAINING THE CHARGING OF A STORE FOR HYDROCARBONS
    Publication number: 20170030276
    Abstract: A method for ascertaining the charging of a store for hydrocarbons originating from a fuel tank of a vehicle is characterized in that the charging of the store is determined from a variable characterizing the fuel outgassing with the aid of a model which maps the vapor pressure curve of the fuel.
