CARBON CANISTER ASSEMBLY AND AN ENGINE

The application discloses a carbon canister assembly and an engine, which relates to the technical field of auto parts. A carbon canister assembly comprises a main carbon canister and an auxiliary carbon canister; The main carbon canister has a first cavity, the first cavity is cylindrical, and the first cavity is filled with adsorption material for adsorbing evaporated fuel vapor; The auxiliary carbon canister has a second cavity communicated with the first cavity, the second cavity is in a round table shape, and the diameter of the cross section of the second cavity in a round table shape gradually decreases from bottom to top. An engine comprises the carbon canister assembly. The application can solve the problem that the oil and gas molecules in the carbon powder in the dead corner section area of the cross section of the carbon bed are not easy to be swept away by air, which is helpful to reduce the cost, ensure the adsorption effect and reduce the failure rate.
