🔹Product Overview
Fuel Injector Part No.3023934 is high‑precision PT‑type fuel injector, suitable for K19 and NT855 series diesel engines. It accurately controls fuel delivery quantity and atomizes high‑pressure diesel into fine mist, injecting fuel into combustion chamber for full combustion. This replacement injector solves common engine faults including insufficient power, unstable idling, excessive black smoke, high fuel consumption and cylinder misfire, which are caused by nozzle clogging, plunger wear and internal spring aging. Each injector is strictly bench‑calibrated to keep stable injection performance under long‑term heavy‑load operation for construction machinery, heavy‑duty trucks and generator sets.
