Common rail diesel engines have been prevalent for over a decade, yet issues associated with them persist. These problems can be costly, making preventive maintenance a wise investment for your vehicle. To assist you, we’ve outlined common issues and their causes, along with effective solutions to address them before they escalate.
Common Issues with Common Rail Diesel Engines:
- Smoke
- Power loss
- Rough idle
- Engine rattle
- Contaminated engine oil
- Increased oil consumption
- EGR valve malfunctions
- Intake system deposits
- Turbocharger failures
- Frequent diesel particulate filter (DPF) regenerations
Understanding the Causes of Common Rail problems.
-
Fuel Quality: Using low-quality diesel can lead to injector fouling and combustion issues. It’s advisable to avoid cheaper fuels and refrain from using truck diesel in light common rail engines.
-
Operating Conditions: Frequent short trips, prolonged idling, operating at cool temperatures, and light engine loads can contribute to deposit buildup in the combustion chamber, exhaust system, turbocharger, and DPF.
-
High-Pressure Injection Systems: The elevated pressures in common rail systems can exacerbate wear and tear, especially if maintenance is neglected.
-
Common rail injection systems are very high pressure and high temperature… sufficient to degrade the fuel, leaving deposits in your pumps and injectors, and lowering your fuel’s lubricating ability. Your fuel filter going black is a sign of this happening.
- Sticking fuel injectors… Your fuel injectors then stick and allow excess fuel which also results in engine rattles, carboning up of your EGR valves, turbochargers, DP filters, combustion chambers and more. Piston ring deposits also form, which allows compression blow by pressure into your sump, and heavy soot contamination of your oil. This pressure is released via your crankcase ventilation system into your air intake system. This carries an oil mist which mixes with exhaust soot from your EGR valve, fouling your throttle body and choking up your intake manifold.
How to prevent problems with common rail diesel injectors:
Incorporating a high-quality fuel additive can mitigate many of these issues. For instance, the CRD Fuel Enhancer is designed to clean injectors, improve fuel combustion, and reduce deposit formation. Regular use can lead to smoother engine performance, reduced emissions, and prolonged component life.
CRD Fuel Enhancer to your vehicle is easy to use (you’ll use only 10mL per 80L diesel). Faulty CRD injectors can normally be fully recovered, by just using the CRD Fuel Enhancer. The cleaning and lubricity power ensures that your injectors meter fuel accurately, without over-fueling. It is even cheaper to use than 2 stroke oil and has far stronger lubricity and detergency.
By understanding these common problems and their root causes, you can take proactive steps to maintain your common rail diesel engine’s health and efficiency.
