Bosch Invented for Life
The common rail system is a major advancement in diesel technology. Bosch launched its common rail system for
passenger car diesel engines in 1997, which provides diesel engines with quieter performance, improved fuel economy,
higher torque, and lower emissions.
Each individual engine cylinder houses a common rail injector. When one or more injectors need to be replaced, you may wonder what replacement options you have.
Bosch diesel fuel injector fall into three categories.
- Genuine OE Injectors
- Remanufactured Injectors
- Injectors from an Authorized Bosch Common Rail Field Repair Location
Testing Proves it
Bosch conducted an intense evaluation of non-authorized injectors available in the market. Our evaluation included
testing on our EPS-815 test bench with Bosch patented Shot to Shot (SST) functionality including OEM (original
equipment manufacturer) specifications. After the testing was performed, Bosch did an injector tear-down for
inspection.
More than 50 percent failed, and presented a significant hazard to the engine if installed in a diesel common rail
system. These hazards included:
- Loss of power
- Decreased fuel economy
- Failure to operate after a short period of time
- Increased Noise
- No start
- Smoke
- Engine damage
- Exhaust system damage
Non-OEM Approved Remanufactured Products
Not all remanufactured injectors are the same. The quality of any remanufactured injector depends on the remanufacturing process and components. During our testing process, we have found that many of the components
removed from non-authorized injectors were outside of the original design specifications and some had corrosion and
pitting, which compromises performance.
You might get a great deal on these non-OEM approved products, but you are taking a huge risk that these injectors may not be better than the one you are trying to replace.
What Can I Do?
Make sure your vehicle is being serviced by a reputable shop. Ask about the fuel system components used on your diesel engine to ensure they are from a Bosch approved supplier.
These injectors could operate for weeks or months before causing the engine and exhaust system to malfunction. One failed injector could lead to complete engine failure.
