What are the fuel pressures on a cat C7 ACERT?
The fuel change dictated that the fuel system of the CAT C7 ACERT needed to change to a common-rail injection system. The new common-rail injectors took injection pressures to 25,000-27,500 psi. The fuel transfer pump supplies the fuel to the fuel rail at 280 psi.
What was the cat C7 diesel engine good for?
The electronic configuration was also more robust to offer better fuel management and electronic sensors into the engine. The CAT C7 was really the first heavy duty diesel engine to offer a greatly expanded ECM or electronic computer module.
When does a cat C7 lose its power?
My C7 has plenty of power until the engine temp reaches 150 degrees. Then it experiences the power loss. Runs like a bat out hell until it comes out of cold mode.
What kind of valve actuation does cat C7 use?
Within the design of the C7, the turbos use variable geometry valve actuation controlled by the ECM to adjust the perfect amount of airflow into the combustion chamber. This variable valve actuation also allows for the CAT C7 to offer an integral jake brake on two of the heavy duty diesel horsepower models.
When was the Caterpillar C7 diesel engine made?
The Caterpillar C7 Engine was produced from 2003 – 2009 and was originally touted to be the greatest CAT Engine ever made. However, things don’t always go according to plan. Read about the history and technical specs of this legacy engine. Looking for remanufactured diesel engine parts?
What is the fuel delivery system on a cat C7?
The fuel delivery system on the CAT C7 is hydraulic electronically controlled unit injectors for the mid horsepower models and mechanically actuated and electronically controlled on the higher horsepower models. Both systems are metered and timed to inject multiple bursts of fuel to create a more efficient combustion cycle.
