초록

본 논문은 냉간단조 연료펌프와 다이캐스팅의 연료펌프에 대해 성능 실험과 아세트산이 포함된 에탄올에 250시간 연료펌프를 구동하여 부식성에 대해 실험을 수행하였다. 성능실험을 수행한 결과, 냉간단조된 하부하우징과 다이캐스팅된 하부하우징으로 제작된 연료펌프의 성능은 동등한 수준이었다. 내부식성은 다이캐스팅된 하부하우징보다 냉간단조된 하부하우징이 더 우수하였으며, 냉간단조된 하부하우징이 다이캐스팅된 하부하우징보다 치밀한 조직을 가지고 있었다.

Performance and anti-corrosion of cold forged fuel pumps and die-casting fuel pumps have been tested in this study. Ethanol with 10 ppm of acetic acid is applied for the anti-corrosion test for 250 hours. Performance test result shows that the pumping efficiency of the cold forged fuel pump is equivalent to that of the die-casting fuel pump. The cold forged lower housing has better quality against corrosiveness and finer metallic structure than the die-casting lower housing does.
