난이도 & 준비물
증상
엔진 시작 후에도 글로우 플러그가 계속 켜져 있는데, 이것이 정상인지? 초기 회전 수를 돕기 위해 글로우 플러그가 시동 후에도 작동해야 하는가?
처리 내용
최신 엔진에서는 시동 후에도 글로우 플러그가 켜질 수 있으며, 실제로 켜집니다. 정부에서 디젤 엔진의 탄화수소와 질소산화물 배출을 줄이기 위해 규제를 강화했기 때문입니다. 글로우 플러그는 추운 날씨에 시동을 도울 뿐만 아니라 엔진이 크랭크된 후에도 계속 사이클링하여 시동 배출가스를 줄입니다. 이는 추운 아침에 디젤 엔진이 크랭크될 때 발생하는 스모그를 감소시킵니다. 요약하면, 글로우 플러그는 배출가스와 스모그를 줄이기 위해 엔진 시동 후에도 켜집니다. 연소실은 시동 직후 바로 온도에 도달하지 않습니다. 실린더 헤드, 실린더 벽, 그리고 특히 냉각계통이 가열되는 데 시간이 걸립니다. 이러한 부품들이 충분히 데워지면 배출가스는 정상 수준이 되고 글로우 플러그는 꺼집니다.

BMW M5
I started this thread really with a question about pros and cons of putting an AJP or something else in my scrap Cerbera and it has morphed into a project build thread over time. Brief history:I was thinking about buying myself a fun sports car, there's nothing new in the £50-80k range I would particularly be interested in. Had to feel special, had to be light, "analogue" and not overly-assisted. Had to be manual and i prefer a large capacity NA to forced induction. Ford Mustang maybe, perhaps not quite special enough and a bit porky. Emira - I love Lotus and have had a few but i'm not a fan o
BMW X5
After writing off my BMW 320d halfway through the month, I suddenly found myself in the market for a new car.Once the insurance payout landed, I had just under £5,500 to play with after paying my excess. I spent hours trawling AutoTrader trying to find the right replacement.I'd lined up a BMW X5 that was slightly over budget and was due to view it today... only for it to sell yesterday before I got the chance. Frustrating, but that's just how it goes.I kept looking, but nothing else really grabbed me.Then I spotted a Range Rover Sport on AutoTrader just five miles away. I called the dealership
