Bad injector symptoms diesel

If, however, your vehicle is being plagued with drivability issues, then it might be time to have your diesel fuel injectors looked at. Diesel fuel injectors have come a long way over the past twenty years. Originally designed as a common rail injection system only for trucks, the technology quickly moved into the passenger vehicle market. Older-style mechanical injectors used far lower fuel pressures than their modern counterparts, with the fuel running through much larger passages. This in turn meant that the injectors had a far greater tolerance for general wear and tear, and were less susceptible to damage caused by contaminants and inferior fuel. The advent of the common rail injection systems introduced a far superior level of vehicle performance and improved fuel economy. However, the newer systems are far more complicated than their predecessor, meaning they can often be more costly to repair. They may also have a shorter lifespan. Diesel fuel injectors generally have a shorter lifespan than their predecessors, meaning they need to be replaced more frequently for optimal performance. The life expectancy of a good quality diesel fuel injector is around , kilometres. They should be checked out by a professional at around this time. To prevent premature wear or damage, always ensure that any early warning signs such as those listed above are investigated.

Sometimes, individual components of a diesel fuel injector can be replaced.

If proper maintenance is performed and problematic practices are avoided, the vast majority of diesel owners will go thousands of trouble-free miles without a problem. However, when compared to older diesel injection systems, m odern common-rail diesel injection systems often present more challenges for vehicle owners due to the fact that they can fire two to three times per engine cycle. This is because older diesel injection systems only use about half the fuel pressure modern engines do, and older injectors send the fuel through much larger passages. Modern common-rail diesel injectors also fire two or three times per engine cycle, which doubles the wear on the injector compared to diesels of the past. With that in mind, let's take a look at the most common symptoms that might indicate that a diesel injector is failing. Trouble starting the vehicle or uneven idling.
