What kind of fuel does a Caterpillar C7 use?
The original Caterpillar C7 would change configurations once again in 2007 to adjust to changing market demands. In 2007 diesel fuel itself changed to Ultra Low Sulfur Diesel or ULSD. The fuel change dictated that the fuel system of the CAT C7 ACERT needed to change to a common-rail injection system.
What are the issues with the cat C7 ACERT engine?
The ACERT technology was prone to numerous regeneration issues. Drivers reported low power and low fuel economy. It was common that the CAT C7 ACERT engines would experience overheating when driving up an incline. The cooling fan does not kick in until 235 degrees Fahrenheit while many drivers reported overheating at 200 degrees Fahrenheit.
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.
What are the connecting rods on a Caterpillar C7 ACERT?
The connecting rods in the Caterpillar C7 ACERT are not forged, liked the CAT 3126, but consist of powdered metal with a fractured cap design. There are also various sizes and configuration of the connecting rods depending on the piston used in the engine.
What was the problem with the Caterpillar CAT C7 engine?
The ACERT Technology had a lot of problems for Caterpillar, first with the CAT C7 but more so later on with the CAT 13 and CAT 15 engines. The technology was really the first generation emissions technology for heavy duty diesel engines. The ACERT technology was prone to numerous regeneration issues. Drivers reported low power and low fuel economy.
What kind of fuel does a cat C7 ACERT use?
In 2007 diesel fuel itself changed to Ultra Low Sulfur Diesel or ULSD. 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.

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.
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.

The fuel change dictated that the fuel system of the CAT C7 ACERT needed to change to a common-rail injection system.
What kind of diesel engine oil is cat?
Cat diesel engine oil is a premium oil that greatly exceeds the minimum requirements of API CH-4. Cat® DEO SYN™ (Synthetic Diesel Engine Oil) Cat DEO™ (Diesel Engine Oil) (Brazil Only) Cat DEO™ (Diesel Engine Oil) (Egypt & Saudi Arabia) Cat DEO™ (Diesel Engine Oil) (Worldwide except North America)
What are the fuel pressures on a cat C7 ACERT?

Are there any problems with the cat C7 engine?
If you are interested in their engines, then there are quite a lot of models that you can go for. One of the best ones from them is their CAT C7 engine. While this was a great engine for most vehicles, some users have reported getting problems with it.
What kind of valve does a cat C7 engine use?
There are two different types of valves that these CAT C7 engines use. These include the IAPCV valve as well as the pressure relief valve. If the pressure relief valves on your engine fail then they need to be replaced or fixed. The IAPCV valves usually start to die out and the problem is quite common.
What to do if your C7 engine overheats?
If the coolant levels drop too low then your engine will start to overheat. Considering this if you notice that the CAT C7 engine is overheating too much then you should confirm the level of its coolant. If the problem persists then you can take your vehicle to a professional.
