Abstract:
본 발명은 파워 스티어링 오일리저버의 오일 잔류량 표시장치에 관한 것으로, 작업자가 레벨게이지 캡(10)을 탱크(1)로부터 분리하지 않더라도 확인창(11)을 통해 상기 회전롤러(20)의 표시부(22)를 눈으로 보고 탱크(1)속에 담겨진 오일의 잔류량을 쉽고 정확하게 확인할 수 있게 되므로 작업의 편의성 향상 및 작업시간의 단축을 도모할 수 있을 뿐만 아니라, 오일의 잔류량 파악시에 상기 탱크(1)속으로 이물질이 유입되는 현상도 미리 예방할 수 있도록 된 것이다. 오일리저버, 오일, 잔류량, 표시
Abstract:
PURPOSE: A method for the estimating amount of NOX(Nitrogen Oxide) stored in a denitrification catalyst and an exhaust device using the same are provided to improve the fuel efficiency by controlling spraying amount of a reducing agent and a regeneration time. CONSTITUTION: A method for the estimating amount of NOX stored in a denitrification catalyst(40) is as follows. A mass flow of the NOx stored in a denitrification catalyst is calculated. The mass flow of the NOx thermally attached and detached from the denitrification catalyst is calculated. The mass flow of the NOx chemically attached and detached from the denitrification catalyst is calculated. The true amount of the NOx stored in the denitrification catalyst is calculated using the mass flow of thermally desorbed NOx and the mass flow of chemically desorbed NOx.
Abstract:
PURPOSE: An exhaust system is provided to rapidly normalize purification efficiency of catalyst by rapid heating under fixed operation conditions when degradation degree of nitric oxide purification catalyst or fuel catalyst is higher than a fixed level. CONSTITUTION: An exhaust system comprises an exhaust line(150), a nitric oxide purification catalyst(160), an injector(120), and a controller(110). The exhaust gas exhausted from an engine passes through an exhaust line. The nitric oxide purification catalyst is placed in the exhaust line and reduces nitric oxide included in the exhaust gas. The injector is installed at the front-end of the nitric oxide purification catalyst. The injector additionally sprays fuel for the production of reducing agent. The injector removes nitric oxide stored in the nitric oxide purification catalyst. The controller controls the engine to additionally spray fuel under a fixed operation condition when the nitric oxide purification catalyst is deteriorated. The controller performs rapid heating up to increase the temperature of the nitric oxide purification catalyst.
