20160003122 | UREA FILLER NECK AND UREA TANK FOR PREVENTION OF UREA OVERFLOW AND UREA AFTER-TREATMENT SYSTEM WITH OUTSIDE FILLER NECK - A urea filler neck for preventing a urea overflow includes a filler housing forming a urea path in which urea flows to a urea tank. An injection gun guide is provided in the filler housing. An end of an injection gun is fixed by the injection gun guide to limit an insertion position of the injection gun inserted into an inlet of the filler housing. An injection gun guide flooding phenomenon is generated, in which urea flowing backward from the urea tank rises to block an air flow in the filler housing being generated in the injection gun guide. A filler housing pressure increasing phenomenon is generated, in which a pressure in the filler housing is increased due to blocking of the air flow by the injection gun guide flooding phenomenon being generated in the injection gun guide. | 01-07-2016 |
20130298878 | CANISTER EQUIPPED WITH HEATER - 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. | 11-14-2013 |
20110308394 | CANISTER WITH HEATER - 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. | 12-22-2011 |
20110247592 | CANISTER WITH HEATER - 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. | 10-13-2011 |
