Mathematical Model of Refueling Emission for Gasoline Vehicles and Influencing Factors Analysis

Abstract:

In order to analyze the emission performance during the process of refueling, the mathematical models of refueling emission for vehicle under the proper simplified conditions were established based on the principle of time-varying and mass transfer in this paper. The models were applied to calculate the refueling emission rate of the fuel tank with and without a charcoal canister respectively, and simulation results of the model were analyzed numerically. Conclusions can be obtained as follows: the refueling emission rate of the fuel tank is 1.1201g / L without a charcoal canister; and 1.0815g / L with one, which is 3 - 4% less than the former on average. In addition, the refueling emission rate is positive related to the average temperature of the fuel tank, fuel average temperature and fuel Reid vapor pressure (RVP).
