How does a diesel common rail work?

HOW DOES THE COMMON RAIL SYSTEM WORK? The high pressure pump pressurizes the fuel and transfers it to the rail, a common conduit that serve as pressure accumulator and reservoir. The pressure is regulated by an electronically controlled valve, so that the rail maintains the correct pressure required by the ECU.

Is TDI common rail?

TDI engines using common rail fuel injection (using piezoelectric fuel injectors) were introduced with the Volkswagen Group 32v TDI V8 engine used in the 1999 Audi A8 3.3 TDI Quattro, two years after the 1997 Alfa Romeo 156 2.4-L JTD became the first passenger car to use common rail injection.

It was built for the long haul, too with an air-to-air intercooler, oil-based fueling, and durable internal hard parts.

What is the life expectancy of a 6.7 Cummins?

The life expectancy of a 6.7 Cummins engine generally ranges between 250,000 and 350,000 miles. There's more to the longevity of a Cummins engine than its mileage, though. The mileage of a 6.7 Cummins will specifically depend on the kind of driving you do, not to mention the state of your truck.

What is high mileage for a 5.9 Cummins?

Overall, deleting the DPF and other emissions systems sounds like a really good idea. It prevents clogged filters, reduces maintenance costs, improves performance, and increases gas mileage.

What’s the difference between 6.7 Cummins and high output?

The standard Cummins delivers 370 ponies while the High Output version pushes out 400 horsepower. Both engines feature a compacted graphite iron block, pushrod-operated overhead valves, and a high-pressure common rail fuel injection system in terms of internal, mechanical construction.

Does 6.7 Cummins have glow plugs?

Cummins engines do not have glow plugs. Instead of glow plugs, Cummins engines are equipped with a single heater grid as their heat aid. These grids are more reliable and work by heating all the heat coming into the air intake. Both the 5.9L and 6.7L Cummins engines come with a grid heat system.

Is a 3rd Gen Cummins considered a common rail?
