Abstract

In this paper, we have implemented the unified fuel heater and performance evaluation system for diesel cars. In order to strengthen an engine starting of diesel car, we need to assembly the fuel filter and heater. Especially, this assembly fuel heater is very important in winter, it is necessary for heating to operate the diesel engine. The heater for unifying the sensor and heater body can advance the performance of car and reduce the production cost. Finally, the performance test chamber is needed to evaluate the performance of heater.

본 연구에서는 디젤 차량용 통합형 연료히터 및 성능검사 시스템을 구현한다. 센서와 히터가 분리된 연료히터를 히터내에 센서를 안착시켜 통합함으로써 일체형 통합히터를 개발하고 성능평가시험 시스템 개발을 통하여 시험한다. 디젤 차량은 겨울철 저온환경의 영향을 받아 엔진이 냉각될 경우 일정한 온도 이하로 내려가면 파라핀과 같은 반고체 상태인 왁싱(Waxing)물질을 형성하여 엔진시동이 잘 걸리지 않게 하는 원인이 된다. 이러한 저온시동성을 지원하기 위해 연료히터를 사용하며, 연료히터의 성능을 평가하는 시험챔버가 필요하다. 시험챔버에서 연료히터의 성능검사 항목으로 상온, 극저온, 극고온에서의 동작검사, 시험저항 설정에 따른 저항동작지연시간 및 전류동작지연시간, 온도변화에 따른 바이메탈 지연시간 검사, 블록히터의 전류 및 저항 검사, 히팅 운전검사 등을 수행한다. 이때 연료히터의 시험평가 및 평가 알고리즘을 제시한다.
