After having a common-rail diesel car with low mileage who broke 4th injector, and one year after the 1st injector, I tend to be suspicious about the system.
It features a deposit where fuel is at thousands PSI of pressure, which has the injectors immediately after in the pipeline, so it makes me think it wears too much the injectors and puts them under very heavy stress!
- Thread: All common rail diesels are inherently flawed?
- BASIC PROBLEMS OF COMMON RAIL FUEL SYSTEMS
- What's the reason for the failure of diesel injector?
All seem to accompany my direction of thought.
So my question is: Is the common-rail system unreliable by design?
