Adsorbent circulation for onboard octane on-demand and cetane on-demand

摘要: A vehicular propulsion system, a fuel system and method of operating an internal combustion engine. separation unit that makes up part the may selectively receive separate at least portion onboard flowable adsorbent in order to into octane-enhanced cetane-enhanced components. controller be used determine particular condition engine such can sent one or more chambers within without first passing through during condition, instead situations where require octane-rich cetane-rich mixture another condition.
