A fuel level sensor stuck diagnosis method for a vehicle capable of accurately diagnosing a stuck of a fuel level sensor is disclosed. A general diagnosis of fuel level sensor fixation is that when the fuel level sensor does not generate an electrical disconnection or ground short error, and the vehicle speed sensor is not abnormal, the fuel level is measured when the vehicle is driven without stopping the engine a certain distance after the vehicle is started. If the signal moved smaller than the allowable value, it was determined that the fuel level sensor was stuck. In this case, since the amount of fuel consumed is different when traveling below the specific distance or when driving the same distance depending on the driving conditions, accurate fixation diagnosis of the fuel level sensor 11 has been difficult. According to the present invention, it is possible to accurately diagnose the fixation of the fuel level sensor by monitoring the fuel level signal, which is the output signal of the fuel level sensor, and comparing the accumulated fuel consumption and the diagnostic consumption amount. It is possible to improve the reliability. 자동차, 연료 레벨 센서, 고착 진단 Automotive, fuel level sensor, stuck diagnosis

Quick float holder type level switch

본 고안은 액체 탱크 내부에 설치하여 수위의 변화에 따른 부력에 의해서 온/오프 상태를 출력하는 일명 '오뚜기식 레벨 스위치'라고도 불리고 있는 플로트 타입 레벨 스위치에 관한 것이다. The present invention relates to a float type level switch, also referred to as an 'outlet type level switch' installed inside a liquid tank and outputting an on / off state due to buoyancy caused by a change in water level. 본 고안에 의하면, 플로트 하우징 및 플로트 캡 상호간이 접합된 부위인 플로트 접합부가 3중으로 밀폐된 구조로 확실한 밀폐 효과를 보장받을 수 있기 때문에 액체가 내부로 유입되는 것을 방지할 수 있다. 또한, 플로트 접합부의 구조로 인하여 플로트 하우징과 플로트 캡이 견고한 일체성을 가지므로 내구성이 향상되어 장기간 사용할 수 있는 효과도 함께 얻을 수 있다. According to the present invention, since the float joint portion, which is a portion where the float housing and the float cap are joined to each other, can be guaranteed with a triple sealed structure, the liquid can be prevented from flowing into the inside. In addition, since the float housing and the float cap have a solid integrity due to the structure of the float joint, durability can be improved and a long-term use can also be obtained. 본 고안은 제작하는 과정에서 플로트 하우징의 내부 아래의 공간에 에폭시 몰딩부를 충진한 후, 곧바로 플로트 하우징과 플로트 캡 상호간을 플로트 접합부에 의해서 접합시킨 상태에서, 내부에서 발생된 가스를 가스배출공을 통해 배출할 수 있도록 하여, 에폭시 몰딩시에 생기는 휘발성 가스 성분이 잔류되는 것을 방지하고 이 가스로 인한 내압이 형성되는 것을 방지하여 에폭시 함침이 양호하게 되고, 플로트 접합부의 접합상태에도 악영향을 끼치지 않는다. The present invention fills the epoxy molding part in the space below the inside of the float housing during the manufacturing process, and immediately after the float housing and the float cap are bonded to each other by the float joint, the gas generated therein is discharged through the gas discharge hole. By discharging, it is possible to prevent the volatile gas components generated during epoxy molding from remaining and to prevent the formation of internal pressure due to the gas, so that the epoxy impregnation is good, and the bonding state of the float joint is not adversely affected. 플로트, 레벨, 스위치, 플로트 접합부, 스위치 홀더, 에폭시 몰딩.
