COMMON RAIL INJECTOR
to rust and corrosion problems that can cause sticking internals, meaning poor efficiency and continued running problems. Simple things like regular fuel filter changes, adding a quality fuel treatment or even just buying fuel from the right place can really go a long way toward overall injector longevity. On some models, cracking of the injector body can also be an issue when running extreme rail pressures.
After receiving a set of core injectors to be rebuilt, there are quite a few steps followed to ensure that a “like new” topquality product is assembled and resold. Replacing the common failure items, cleaning everything in an ultrasonic cleaner, measuring tolerances, flow bench testing and perfectly matched injection nozzles are all used to ensure you receive a completed set of injectors that can maximize efficiency, performance and drivability. While a basic remanufacture to stock specifications is most common, Industrial Injection can also rebuild an injector to exceed factory performance with their extrude honed injection nozzles and other internal modifications. Using a state-of-the-art extrude hone machine, technicians can run brand new OEM Bosch injection nozzles through the honing process to enlarge the holes in the nozzle to improve fuel flow. There’s everything from a mild 50-hp nozzle that can improve a truck’s mileage, power and street-ablilty without putting undo stress on the powertrain to all-out, competition-only, 500+ horsepower nozzles for those wanting to make a statement on the sled pull or dragstrip. Over the course of the last year, with the help of a new in-house engine dyno, Industrial Injection has pushed multiple Cummins past 2,500 hp using their cutting-edge common rail Cobra injectors.
