Fuel pressure is normally 70-90 psi. That's correct according to the techs at the CAT dealer and consistent with what gruse and birdhunter have observed. WebCat C12 Diesel Marine Propulsion Engines, with ratings of 578-609 mhp (570-600 bhp) at 2300 rpm, meet IMO I emission standards. since that time the engine has been overhauled with new pistons, head, injectors, turbo, cam followers, and manifold pressure sensor. I've seen it touch 24 psi briefly on occasion.
That's correct according to the techs at the CAT dealer and consistent with what gruse and birdhunter have observed. fuel pressure with mechanical gauge at filter housing is normal. I can barely keep a 42k load going 70. it will see 23-28 psi from 1500 rpm's to 1800 and 10-20 psi from 1200 to 1350 ish. Webeverything under the valve covers including valve adjustment measurements, visual inspection of rods, rockers, valves, and injectors, and pressure tested fuel system. For accurate air intake system pressure readings, the MAP sensor will measure the amount of pressure inside the intake manifold.

WebYou can easily increase boost pressure over wastegate spring pressure by using a boost controller, but you cant achieve a maximum boost level under the wastegates spring pressure. Something as simple as a broken hose clamp could allow boost pressure to blow the hose off.
This started about 8 month ago. If you have an exhaust brake, VERIFY that the butterfly valve is not stuck shut. I'm in the uk and have a CAT C12 in a tipper -dump truck. Still no power. Running about 60 mph on cruise control it would shift down one gear and hold about 55 mph. However, normal oil pressure is around 50 psi. I used to get 27 to 30 psi. WebThe turbocharger boost pressure forces plunger (4) to move down to valve seat (5). Of course, boost pressure is a function of engine load. My 2002 c12 does not have the power it used to. It's only got about 300,000 miles on it, but it doesn't seem to boost until about 1700rpm. Still no power. However, normal oil pressure is around 50 psi. That is well above the green band. Running about 60 mph on cruise control it would shift down one gear and hold about 55 mph. There is also a wide range of optional I've seen it touch 24 psi briefly on occasion.
That is well above the green band. Check "plumbing" between turbo and CAC and CAC and engine. WebCat C12 Diesel Marine Propulsion Engines, with ratings of 340-490 bhp (254-366 bkW) at 1800-2300 rpm, meet IMO II emission standards with the exception of the 497 mhp (490 bhp) rating at 2300 rpm which meets IMO I emissions standards. When the engine is stopped, the absence of boost pressure allows the plunger to rise to the open position, which allows condensation from the aftercooler to drain out. fuel pressure with mechanical gauge at filter housing is normal. If a wastegate is fitted with springs rated to 7PSI, it will open when it receives 7PSI of pressure to the actuator. The plunger must close against the seat at a pressure of 27.5 kPa (4 psi). If you have an exhaust brake, VERIFY that the butterfly valve is not stuck shut. I have checked for leaks in intercooler and pipes. I've seen it touch 24 psi briefly on occasion. Of course, boost pressure is a function of engine load. When was it last lubed? It is very flat below that, and doesn't pull very well.
