Now the reason you see it spike is the ICP is the desired and the IPR is the regulated reading in the head..those 2 numbers have to be within so much of eachother.. at WOT 3000psi is still good numbers..thats 21 000psi fuel pressure in the cylinder lol its working ...

Web31 de jul. de 2024 · Sunday at 7:48 PM. #1. Finished up doing a fuel system redo on my 1997 OBS F350 7.3 Powerstroke. It starts up and idles smooth for the first 8-10 seconds, then goes into a rough idle. It runs strong off idle, though maybe seems a little light on power at highway speeds. This truck has 375K on the ticker and last spring it started running … Web• Check the Injection Pressure Regulator (IPR) Duty Cycle under a load. • Drive the vehicle at Wide Open Throttle (WOT) under a load (pulling a hill). • Verify the IPR Duty Cycle … biological cybernetics几区

Web2 de dez. de 2024 · The pulse width is modulated from a duty cycle of 8 to 50% to control injection control pressure from 3.4-20.7 MPa (500-3000 psi). The IPR is mounted in the high pressure pump (HPOP) and achieves injection control pressure regulation by discharging excess oil through a shuttle valve into the front cover and back to sump.

When you unplugged the ICP, the PCM reverted to default numbers - what you were seeing isn't real. You could also have low fuel pressure that is partially compensated for when the PCM went into … WebDuring the suction cycle or one-half of a revolution, the pistons create a vacuum that forces oil in. On the other half of the revolution, the pistons discharge oil. In the 7.3L HPOP, the pistons measure 0.436-inches in outer diameter. A 15-degree pump’s internal cc size is roughly 6.8 cc’s, while the 17-degree pumps is 7.2 cc’s. daily mail weird news
