Ways to Find Out If the Common Rail Injector Is Failing
A failing common rail injector can lead to issues with the overall performance of your car. Any problems with the injector need fast repair to avoid the possibility of engine failure. But if you do not understand your engine system, you might not know if it is failing. Here are warning signs of a failing common rail injector you need to know.
Knocking Sound from the Engine
The engine should not be producing knocking sounds when you are driving. Such noises are a sign of issues with the system, and you should fix them before they cause engine failure. Poor timing in the combustion system is a common cause of the knocking sound. When the movement of the injector and the piston is not in-sync, then it causes the knocking sounds.
A faulty injector will strain the rail pumps and the control units and cause a banging sound. The noise is as a result of the system trying to understand the false measurement of the failing injector.
Change in the Vehicle's Emission
Most drivers ignore the emissions of their auto, yet it is the simplest way to tell if your engine is functioning as required. Smoking of the car is a sign that the engine is running as needed. If the common rail injector is failing, you might not see any smoke.
When the car is producing thick smoke, then the exhaust area is likely to be dirty. If the smoke is black and has oil, then it is a sign that the injector is not working. The best option is to contract professionals to examine the auto and fix the injector.
Rough Running of the Car
A failing common rail injector could result in the rough running of the vehicle. The rough driving does not happen overnight, but it creeps in gradually. If a driver is not cautious, they might not notice the change and take the appropriate action. In case you notice slight vibrations when driving, then you might have issues with the injector.
You can also tell if the vehicle is operating as required depending on the way it starts. For instance, a difficult time when starting your car can be a sign that the fuel delivery to the engine is not efficient. When the injector is not delivering the fuel as needed, it will cause the rough running of the car and damage the engine if not fixed.
One of the ways to keep up with what is happening with the common rail injector is by having scheduled preventive maintenance. It is best to get the auto part professionals to fix the faulty injectors and update you on what is happening in the internal mechanisms. Call in a mechanic when you notice any of the three issues highlighted, and contact a supplier of common rail injectors in your area if you need to replace yours.
