Abstract: PURPOSE: An exhaust pipe apparatus for a vehicle is provided to attenuate corresponding high frequency which is installed between a center muffler and a main muffler. CONSTITUTION: An exhaust pipe apparatus for a vehicle comprises a front pipe(10), catalyst(20), a main muffler(40), a tailpipe(50), and an exhaust adapter for high frequency(60). The front pipe absorbs the vibration of an engine and a car body through a vibration isolator. The catalyst oxidizes exhaust gas at constant temperature. The center muffler reduces the first noise of exhaust gas which is discharged at high speed. The main muffler reduces the second noise of the exhaust gas which is discharged at high speed. The tailpipe guides the exhaust gas to the outside of the vehicle and reduces airstream sound. The exhaust adapter for the high frequency is installed between the center muffler and the main muffler.

Abstract: A refrigerant system using a refrigerant filling condenser is provided to improve productivity by shortening a refrigerant injection time and reduce the cost required to frequently inspect line facility and repair. A refrigerant system includes a compressor(1), a condenser(2), a receiver tank, low-pressure and high-pressure hoses(7,8) for transferring a refrigerant, and an expansion valve(4). The compressor compresses the refrigerant into a high-pressure liquid and transmits the high-pressure liquid to the condenser. The condenser changes the high-pressure liquid to a low-pressure liquid according to heat exchange. The receiver tank is fixed to one side of the condenser. The condenser is a refrigerant storing condenser. A drain plug(11) is placed at the inlet and outlet of the compressor. The drain plug discharges air from the hoses. A drain hole is formed at a port at the side of a refrigerant hose connected to the condenser. A check valve for sealing and filling the refrigerant is set at a port at the side of the condenser.

Abstract: 본 발명은 연료전지 차량의 시동 방법에 관한 것으로서, 복수의 보조 전원을 탑재한 연료전지 차량에서 보조 전원의 전압을 DCDC 컨버터를 이용해 부스팅한 뒤 연료전지 보기류(BOP)에 공급하여 연료전지 차량을 시동하는 방법에 관한 것이다. 특히, 본 발명은 연료전지 시동을 위한 보기류 구동을 위해 저전압 보조배터리와 고전압 보조배터리 전원 모두를 각각의 전원에 연결된 DCDC 컨버터를 이용하여 고전압으로 부스팅한 뒤 사용함으로써, 전력원을 분산하여 서로 간의 부담을 줄여줄 수 있고(시동시 보조배터리 전원의 부하 편중 부담 감소), 어느 한쪽의 초기 전압이 낮은 경우나 잦은 시동 실패시에도 배터리의 방전 부담 없이 시동을 다시 시도할 수 있도록 한 것이다.
