Diesel injectors are crucial for engine performance but can fail due to harsh conditions. Common issues include nozzle needle seizing, carbon buildup, increased needle lift, and air in fuel lines. Seizing often results from poor heat dissipation, dirty fuel, or improper maintenance. Carbon deposits block nozzles when fuel and oil don’t burn completely, mixing with dust. Increased needle lift reduces power and raises fuel use, often caused by wear. Air in fuel lines leads to abnormal engine sounds and reduced cylinder performance. Prevention includes proper installation, clean fuel, regular maintenance, and correct operation. Solutions involve polishing and reassembling injectors to restore function.
