Abstract: A vehicle canister device includes a main canister including an inlet port through which evaporative gas is introduced from a fuel tank, an outlet port through which the evaporative gas introduced during operation of an engine is discharged to an intake side of the engine, and an internal space for filling activated carbon. The vehicle canister device also includes an auxiliary canister mounted in fluid-communication with the main canister and configured to allow external air to flow into the main canister through an atmosphere port provided on the main canister or the evaporative gas to flow therethrough upon stop of the engine. The auxiliary canister includes a plurality of activated carbon layers each filled with an activated carbon and a plurality of air layers disposed between the activated carbon layers.

Abstract: The present invention provides a canister mounted in a vehicle to reduce the discharge of fuel gas and, more particularly, a canister with a heater configured such that fuel gas adsorbed onto active carbon filled in the canister is more easily desorbed from the active carbon and introduced into an engine. The canister with the heater according to the present invention includes a canister housing including a tank port and a purge port, which are provided at the top thereof, and a plurality of inlet holes provided on one side thereof to introduce air; and a heater connected to the top of the plurality of inlet holes of the canister housing and including an air port provided at the top thereof, an open bottom, and a heater module provided therein.

Abstract: The invention provides a canister for reducing emissions of fuel gas. Fuel gas absorbed onto active carbon inside a canister can be easily desorbed from the active carbon and then flow into canister in the engine. The canister, which is combined with fuel tank and throttle pipe for absorption and desorption of fuel gas generated in fuel tank, has following components: a fuel tank port and an air inlet formed at the upper end of one side; a junction pipe arranged in upper parts of this side; a canister body with a plurality of convex is formed; a junction configured to fit the junction pipe on the canister body formed at upper end of the canister body and a plurality of hooks connected with a plurality of convexes on the canister body are provided; air inlet set on an upper side, a heater with a heater module is set inside.

Abstract: Disclosed herein is a canister mounted in a vehicle to reduce the discharge of fuel gas. The canister of the present invention includes at least one pocket installed in a canister housing. The pocket divides the inner space of the canister housing into first and second spaces. A heater is inserted into the pocket from the outside of the canister housing. The heater generates heat during running of an engine to heat active carbon filled in the canister. When the active carbon is heated, fuel gas adsorbed onto the active carbon in a liquid phase is easily evaporated and supplied to the engine. The heater can significantly improve desorption efficiency of the fuel gas by the active carbon.
