Disclosed is cold-start fuel vapor emission control system for an internal combustion engine having an intake manifold and a fuel tank, comprising the following components: (1) a housing for containing an honeycomb adsorber for adsorbing fuel vapor; (2) a vapor passage for fluidly connecting the housing and the fuel tank; (3) a charging system for measuring the quantity of adsorbed fuel vapor and for, if necessary, increasing the amount of adsorbed fuel vapor to a level sufficient to 'vapor-only' start the engine; (4) a purging passage connecting the housing to an intake manifold for introducing a mixture comprised of the fuel vapor and air to the intake manifold. In a preferred embodiment, the honeycomb adsorber comprises a monolithic, binderless honeycomb structure having a continuous activated carbon phase.
