What kind of air inlet system does cat C7 use?
With the ACERT design the smaller CAT C7 models used an air inlet system with multiple traditional wastegated turbos to boost air intake flow and pressure. The more midsized hp models used only a single turbo while the larger horsepower models used dual turbochargers working in conjunction for optimal airflow.
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 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’s the life expectancy of a cat C7 engine?
B10 is the average life expectancy of an engine measured in miles where 10% of the produced engines failed and needed a major overhaul. Consequently, B50 is the average miles where 50% of the engines failed. With the CAT C7 the B50 rating of 450,000-500,000 miles.
Where do I Find my caterpillar ESN number?
Where Do I Find My Caterpillar ESN? Most engine serial numbers can be found on the dataplate, which is typically on the driver side of the valve cover. Not all engines are consistent in where they put these information plates. The dataplates for a certain type of engine can be found in various places depending on the model.
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.
Where are the serial numbers on a Caterpillar engine?
Most engine serial numbers can be found on the dataplate, which is typically on the driver side of the valve cover. As you’ll see later in this article, the dataplates for a certain type of engine can be found in various places depending on the model. However, Caterpillar is pretty consistent with their location.
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.
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 are the filters for Cat on-highway engines?
