Remanufactured CAT® EUI Injectors With a Difference

“Good Enough” Isn’t for DFT

When it comes to large diesel engines, poor engine performance, excess fuel consumption and reduced operational life are all symptoms of bad fuel injectors. Unfortunately, it’s an all-too-common problem because when it comes to EUI injectors, even newly re-manufactured ones, performance can vary by 20% or more from injector to injector and still be considered “acceptable.”

That’s why DFT is different. We know the EUI injector is an electromechanical component that requires both mechanical and electronic inspection, replacement or refurbishment, and testing to ensure each unit is restored to peak condition. DFT remanufactured EUIs have the lowest variance and highest quality in the industry, which is why so many of our customers say our injectors aren’t just “like” new, they’re better than new.

Fuel Spray Variance Kills Performance

As measured in EUIs from different (re)manufacturers

Performance variance in EUI injectors

DFT injectors have the lowest spray variance so engines run longer and more efficiently.

DFT Advantages

Why we’re a global leader in EUI research, engineering and remanufacturing

DFT sources its components from hand-selected suppliers and specifies premium materials like Viton, SAE 4130 and Chromium Silicon alloy to ensure superior performance and extended life. DFT replaces up to 80% of old components with new, higher quality ones compared to an industry standard of less than 50%.

DFT is a lean manufacturing facility employing an ISO-level cleanroom, state-of-the art tools and technology, and production standards that meet or exceed OEM/SAE/ASTM specifications. Each DFT injector follows lean single piece flow and is laser serialized to tie the injector to a manufacture date and technician.

All DFT injectors are reground and honed to ensure optimum performance. Each unit is dyno tested and provided with up to four unique trim codes and files optimized for each injector. This allows operators to eliminate variation, balance and fine tune injector performance in an operating engine.

Every EUI injector produced by DFT must go through a battery of mechanic and electronic tests in order to pass DFT’s quality assurance standards. If any piece fails any portion of the testing battery, the unit does not ship.

DFT not only provides a team of skilled service and support technicians, but also offers 24 hour assistance for engine issues worldwide with its global network of engine specialists.
