Tech tips From a Navistar turbo to Audi fault codes

摘要

Do you believe in magic?? What else could account for the operation of the high pressure oil system on Ford's power stroke diesel? This much I can assure you — it was not designed by Harry Houdini, but hey, maybe a distant cousin?! What I do believe is that the oil system used on this engine is an engineering marvel! While space limitations won't allow me to babble on endlessly, hopefully this tech tip will give you a better understanding of how this system works. When the engine is cranked over, crank-case oil pressure builds. In addition to lubricating all of the engine's internal moving parts, the oil has one more path to follow. It travels through the timing cover to a high-pressure injection reservoir mounted on top of it, used to supply oil to the high pressure oil pump. This pump then increases the pressure to the high levels needed to pop open the injectors, and to increase the pressure of the diesel fuel entering the cylinders for complete combustion.
