This is the cause of the problem if the pilot fuel pressure is high and the main fuel pressure is high. Our focus is locked on maximizing performance with simpler engine systems and reduced installation complexity through modular, flexible designs. Systems Operation C9 Industrial Engine Media Number -RENR7597-03 Publication Date -01/01/2008 Date Updated -31/01/2008 i02927532. The CAT C-9 should get 7.5 to 8 mpg. The Cat® C9 ACERT⢠Industrial Diesel Engine is offered in ratings ranging from 205-280 bkW (275-375 bhp) @ 1800 ... vapor pressure of 1 kPa (.295 in Hg), and 25°C (77°F). Follow the procedure recommended by Caterpillar on C9 service manual. The Cat C-9 (400 HP) needs a constant flow of diesel fuel at 58 psi low idle to 81 psi at high idle to run properly. Previous Screen Product: INDUSTRIAL ENGINE Model: C9 INDUSTRIAL ENGINE JSC Configuration: C9 Industrial Engine JSC00001-UP. Page 1 of 25. At low idle, fuel pressure at the filter inlet (8) should read from 400 to 435 kPa (581 to 63 psi). you have fuel entry and pressure regulator on the other side; easy to test Fuel pressure at the inlet to the secondary fuel filter (8) should read between 400 and 525 kPa (58 to 76 psi) during normal operating conditions under load. Shutdown SIS. Is this normal. The Cat C9.3B combines a new high pressure common rail fuel system and advanced aftertreatment technology to produce 340 kW of power. I have a CAT C9 2006 ACERT engine and the idle pressure is 52 lbs and at 2200 rpm no load 65 lbs. 4077-16 : Aftertreatment #1 Fuel Pressure #2 : High - Moderate Severity (2) This code relates to pilot fuel pressure. With exceptional power density, the C9.3B allows for platform downsizing while maintaining reliability and durability. The nozzle inside the ARD combustion head is plugged. 2 - crack on cylinder head. This low fuel pressure also triggered the low turbo boost fault code to be logged . Many Cat C-9 engines cannot maintain constant fuel flow with the fuel tank located 38 feet away from the engine. Fuel pressure regulators maintain fuel pressures; Attributes: Cat® parts are manufactured to precise specifications and are built for durability, reliability, productivity, less environmental impact, and reuse test head with pressure. Fuel mixed with oil can be from: 1 - transfer (lift) pump leaking by pump shaft seal. This low fuel pressure was one of the causes for the check engine light to illuminate and for the engine derations/loss of power. Lift pump is fitted in the back of HEUI pump. I have no issues or problems with performance other than a ScangaugeD shows max HP at about 330HP.

The fuel enable valve is stuck open. According to CAT, the tank should be no more the 4 to 6 feet from the engine. The Cat spec for fuel pressure on this generation of C9 is 55 at idle-75 psi at full load. Fuel System â¦
