[QUOTE="Chatham036, post: 1399131, member: 13047"] I am a fan of analogies. I have one that will explain this quiet well actually. Take your typical spray bottle like the one pictured. [IMG]http://images.containerstore.com/catalogimages/148194/12ozSprayBot176010_x.jpg[/IMG] Now when you use this bottle, pull the trigger in slowly. Notice how the liquid that comes out does not have a nice, consistent mist? Much larger droplets of liquid should be observed. Now squeeze the trigger in at a quick pace. Notice how the liquid now becomes a mist? This is because you are generating a higher pressure using the internal intensifier piston in the sprayer. In relation to our Heui injection system, the ICP from your high pressure oil rail is the same as your finger is on the spray bottle. The more pressure you put, the harder it drives the intensifier piston, the better atomization is achieved at the nozzle. Increased ICP also causes a greater volume of fuel to be injected in a given period of time. In explanation of the attachment: Where a stage 3 (238cc - 80 %) will deplete at 3.5 ms of pulsewidth, this is at 3,000 psi ICP. With only 2,000 psi ICP, it will require 4.0 ms PW to deplete the same 238-80 [/QUOTE]
