Stiction Explained Solve 6 0 7 3 Power Stroke Heui Injector Issues As previously mentioned in 1993 caterpillar developed the heui injection system, and international, under license from caterpillar created the powerstroke engine for ford. The heui advantage one of the first largest evolutionary steps of high pressure diesel injection technology is thehydraulically actuated electronic unitinjection (heui) system. in the 1980’s when manufacturers began exploring technical solutions for upcoming emission standards, they realized that mechanically governed fuel systems had several handicaps. the primary disadvantage is mechanical.
Stiction Explained Solve 6 0 7 3 Power Stroke Heui Injector Issues I used "how does heui work on the 7.3" in a google, and got a bazillion hits. understand heui, and you'll understand how the 7.3 injection system "works". In 1993, cat introduced "hydraulically actuated electronic unit injection" (heui), where the injectors are no longer camshaft operated. first available on navistar's 7.3 litres (445.5 cu in), v8 diesel engine. heui uses engine oil pressure to power high pressure fuel injection, where usual method of unit injector operation is the engine camshaft. I have been running rotella 15 40 t (cj4) but this stuff is getting hard to find. seems that rotella 15 40 t4 is the newer version. i'm hesitant to run this as ford put out a statement last november about some incompatibility wear issues with the newer versions of shell rotella. i don't know. Edit around post 1xx someone asked me to consolidate the post. the post turned from a what is done to make a larger injector to how you or i can make a modest sized injector at home or in conjunction with a local machine shop. so i made mine with the help of a local machinist since i do not have.

Wie bereits erwähnt, entwickelte caterpillar 1993 das heui einspritzsystem, und international, unter lizenz von caterpillar, schuf den powerstroke motor für ford. I've researched this and haven't found an answer. why did ford navistar decide to go with heui injector systems with the 6.0? what are the benefits of heui over a standard common rail system?. 6.0l injector spool valve operation (refer to figure 1) – the spool valve is located in a bore in the stator housing; coils and coil housings positioned on both ends of the stator housing serve as end caps to seal the assembly and limit valve travel (0.432 mm). an open coil on one side of the stator housing and a close coil on the other arealternately energized during engine operation to. Heui stands for hydraulic electric unit injector. they work by utilizing high pressure oil provided by a high pressure oil pump (hpop) and pressurize the fuel inside the injector.
