A comment on another thread raises this question in my mind. Why do our 617's have glowplugs but my CAT 3208 doesn't? The CAT smokes a lot more upon startup at all temperatures, but it seems to start at low temperatures when there would be no hope of starting the 617 without glowplugs. I know some diesels have intake heaters etc, but the CAT doesn't. There must be some design difference that permits it to start at low temperatures without glowplugs but I don't know what it is. Can someone enlighten me?
