Does a Faulty Injector in a Four-Cylinder Diesel Engine Have an Impact?
2 Answers
A faulty injector in a four-cylinder diesel engine can cause insufficient power. Cleaning cycle for injectors: Generally, most users are advised to clean them every 20,000-30,000 kilometers. For vehicles in good condition and using high-quality fuel, this interval can be extended to 40,000-60,000 kilometers. Risks of long-term neglect in cleaning injectors: If injectors are not cleaned for a long time, clogging will become more severe, leading to poor fuel injection, improper spray angle and atomization. This results in rough engine performance during idling, acceleration, or full-load conditions, significantly reducing engine power and increasing fuel consumption.
My old diesel pickup truck had a failed third-cylinder fuel injector last year, and the shaking was like sitting on a massage chair! When the engine was misfiring, the whole truck was gasping, with black smoke pouring out of the exhaust pipe, and the fumes were so pungent they stung the eyes. The worst part was that the remaining injectors had to work twice as hard, causing imbalanced fuel pressure that could lead to abnormal piston ring wear and, over time, even cylinder scoring. I stubbornly pushed through three days of deliveries, only to completely clog the DPF particulate filter, costing me an extra 5,000+ in repairs. Take my advice: if one fuel injector fails, don’t try to tough it out—small problems turning into major issues just aren’t worth it.
