Abstract: A system recognizes a check-up time of a filter of an air cleaner. The system includes a power unit that supplies power to the system, a pressure sensor that measure pressure of a filter, at an outlet connected with a filter unit, a conversion circuit that converts the measured value into a predetermined type, a processor that controls the measurement period of the pressure sensor and receives and compare the measured value converted by the conversion circuit with a predetermined reference value, and a display unit that displays a filter replacement period.

Abstract: Disclosed herein is an air duct assembly for vehicles which reduces noise generated by the flow of intake air which flows along a path of the air duct provided in a vehicle and is fed to an engine. The air duct reduces the noise of a low frequency range in initial engine start operation, and in addition, the noise of a whole frequency range, thus allowing a vehicle to be traveled while providing the environment having minimum noise to a driver and passenger riding in the vehicle. Therefore, it is not necessary to install an additional resonator.

Abstract: The vehicle canister comprising: the first chamber filled with the active carbon and funneled with the tank port, where the evaporating gas is infused through and the second chamber filled with the active carbon and funneled with the atmosphere port and neighboring the first chamber via the isolation wall. Also, it involves the vehicle canister installed in the canister housing which has the absorption and desorption improver to improve the absorption and desorption efficiency with heat conduction with temperature change of the active carbon occurred during the absorption and desorption of evaporation gas infused into the canister housing. The absorption and desorption improver is composed with the first and the second absorption and desorption improver.
