Abstract

An evaporative emission control canister system comprises an initial adsorbent volume having an effective incremental adsorption capacity at 25° C. of greater than 35 grams n-butane/L between vapor concentration of 5 vol % and 50 vol % n-butane, and at least one subsequent adsorbent volume having an effective incremental adsorption capacity at 25° C. of less than 35 grams n-butane/L between vapor concentration of 5 vol % and 50 vol % n-butane, an effective butane working capacity (BWC) of less than 3 g/dL, and a g-total BWC of between 2 grams and 6 grams. The evaporative emission control canister system has a two-day diurnal breathing loss (DBL) emissions of no more than 20 mg at no more than 210 liters of purge applied after the 40 g/hr butane loading step.

Claims (29)

1 . An evaporative emission control canister system, including one or more canisters and comprising:

a fuel-side adsorbent volume; and

at least one subsequent adsorbent volume having an effective butane working capacity (BWC) of less than 3 g/dL,

wherein the fuel-side adsorbent volume and the at least one subsequent adsorbent volume are located within a single canister, or in separate canisters that are connected to permit sequential contact by fuel vapor, and wherein the canister system has a two-day diurnal breathing loss (DBL) emissions of at least one of: (i) no more than 20 mg at no more than 210 liters of purge applied after a 40 g/hr butane loading step, or (ii) no more than 20 mg at no more than 100 bed volumes (BV) of purge applied after a 40 g/hr butane loading step as determined by a lab-based 2012 LEV III California Bleed Emissions Test Procedure (BETP) section D.12.

2 . The canister system of claim 1 , wherein the at least one subsequent adsorbent volume has a g-total BWC of 0.8 to 6 grams.

3 . The canister system of claim 1 wherein the at least one subsequent adsorbent volume has an effective butane working capacity (BWC) of from 1.6 to less than 3 g/dL.

4 . The canister system of claim 1 , wherein the at least one subsequent adsorbent volume has an effective volumetric incremental adsorption capacity at 25° C. of ≤24 grams n-butane/L between vapor concentration of 5 vol % and 50 vol % n-butane as determined by Micromeritics volumetric analyzer.

5 . The canister system of claim 1 , wherein the at least one subsequent adsorbent volume has an effective volumetric incremental adsorption capacity at 25° C. of ≤16 grams n-butane/L between vapor concentration of 5 vol % and 50 vol % n-butane as determined by Micromeritics volumetric analyzer.

6 . The canister system of claim 1 , wherein the fuel-side adsorbent volume comprises activated carbon.

7 . The canister system of claim 1 , wherein the at least one subsequent adsorbent volume comprises activated carbon.

8 . The canister system of claim 7 , wherein the subsequent adsorbent volume comprises a volumetric diluent including at least one of an inert spacer particle, a trapped air space, a foam, a fiber, a screen, or a combination thereof.

9 . An evaporative emission control canister system, including one or more canisters and comprising:

a fuel-side adsorbent volume; and

at least one subsequent adsorbent volume having an effective volumetric incremental adsorption capacity at 25° C. of less than 35 grams n-butane/L between vapor concentration of 5 vol % and 50 vol % n-butane as determined by Micromeritics volumetric analyzer, and an effective butane working capacity (BWC) of less than 3 g/dL,

wherein the fuel-side adsorbent volume and the at least one subsequent adsorbent volume are located within a single canister, or in separate canisters that are connected to permit sequential contact by fuel vapor.

10 . The canister system of claim 9 , wherein the at least one subsequent adsorbent volume has a g-total BWC of 0.8 to 6 grams.

11 . The canister system of claim 9 , wherein the at least one subsequent adsorbent volume has an effective butane working capacity (BWC) of from 1.6 to less than 3 g/dL.

12 . The canister system of claim 9 , wherein the at least one subsequent adsorbent volume has an effective volumetric incremental adsorption capacity at 25° C. of ≤24 grams n-butane/L between vapor concentration of 5 vol % and 50 vol % n-butane as determined by Micromeritics volumetric analyzer.

13 . The canister system of claim 9 , wherein the at least one subsequent adsorbent volume has an effective volumetric incremental adsorption capacity at 25° C. of ≤16 grams n-butane/L between vapor concentration of 5 vol % and 50 vol % n-butane as determined by Micromeritics volumetric analyzer.

14 . The canister system of claim 9 , wherein the fuel-side adsorbent volume comprises activated carbon.

15 . The canister system of claim 9 , wherein the at least one subsequent adsorbent volume comprises activated carbon.

16 . An evaporative emission control canister system, including one or more canisters and comprising:

a fuel-side adsorbent volume having an effective volumetric incremental adsorption capacity at 25° C. of greater than 35 grams n-butane/L between vapor concentration of 5 vol % and 50 vol % n-butane as determined by Micromeritics volumetric analyzer; and

at least one subsequent adsorbent volume having an effective volumetric incremental adsorption capacity at 25° C. of less than 35 grams n-butane/L between vapor concentration of 5 vol % and 50 vol % n-butane as determined by Micromeritics volumetric analyzer, and an effective butane working capacity (BWC) of less than 3 g/dL,

wherein the fuel-side adsorbent volume and the at least one subsequent adsorbent volume are located within a single canister, or in separate canisters that are connected to permit sequential contact by fuel vapor.

17 . The canister system of claim 16 , wherein the at least one subsequent adsorbent volume has a g-total BWC of 0.8 to 6 grams.

18 . The canister system of claim 16 wherein the at least one subsequent adsorbent volume has an effective butane working capacity (BWC) of from 1.6 to less than 3 g/dL.

19 . The canister system of claim 16 , wherein the at least one subsequent adsorbent volume has an effective volumetric incremental adsorption capacity at 25° C. of ≤24 grams n-butane/L between vapor concentration of 5 vol % and 50 vol % n-butane as determined by Micromeritics volumetric analyzer.

20 . The canister system of claim 16 , wherein the canister system has a two-day diurnal breathing loss (DBL) emissions of at least one of: (i) no more than 20 mg at no more than 210 liters of purge applied after a 40 g/hr butane loading step, or (ii) no more than 20 mg at no more than 100 bed volumes (BV) of purge applied after a 40 g/hr butane loading step as determined by a lab-based 2012 LEV III California Bleed Emissions Test Procedure (BETP) section D.12.
