Fuel Under Pressure

Diesel fuel injectors make things work

The injector itself has very few moving parts. The solenoid controls the start and stop of injection and variations within the cycle. Many injectors control the rate of injection or provide several injections per cycle depending how the control module is programmed. 

High pressure works on the nozzle needle opening it and atomizing fuel into the combustion chamber. Once the appropriate amount of fuel has been injected, the needle closes and the cycle repeats itself.

When you consider that an injector must perform over millions of cycles, the importance for strong quality measures during the design and manufacturing of these systems becomes clear. Furthermore, as remanufactured product grows, the process controls, cleanliness requirements and testing results becomes more complex and very interactive with the overall vehicle functions.

All told, modern injectors contain technologies that have evolved and been proven over many engine hours and in all displacements of compression ignition engines. 

Vast varieties of the basic injector theme exist today and still operate worldwide. Modern systems have learned to incorporate digital controls for vast increases in flexibility and application, while maintaining the expected longevity and durability of years past.

Future advances in materials and electromechanical technology will continue to make engines cleaner and more economical hosting higher levels of integration with vehicle management for optimal owner performance.

At AMBAC International, we manufacture and remanufacture diesel fuel injection for some of the toughest engines in the world, and we’ve been doing it longer than anyone in the industry.

So what exactly is remanufacturing? As the automobile industry expands rapidly around the world, so too does the demand for fuel injectors and for practical long-term ways to produce them at a reasonable pace.

Remanufacturing is defined as, “The rebuilding of a product to specifications of the original manufactured product using a combination of reused, repaired and new parts. It requires the repair or replacement of worn out or obsolete components and modules.” And it  is one of the most popular ways to accomplish this goal.

Your engine’s fuel injector is one of the most dynamic yet integral parts of your vehicle’s smooth and functional operation. Whether you are looking for/working with a full set of fuel injectors, a smaller set, or even just one injector, purchasing a remanufactured injector is the key to improving your efficiency and gas mileage, all while doing your part in contributing to industrial and environmental sustainability.

Should you like to learn more about the remanufacturing process or are looking for a remanufactured part, AMBAC International would be happy to help. Email Lori Murray at lmurray@ambac.net or visit our website https://ambacinternational.com/.
