Denso Common Rail Injector Nozzle DLLA139P887

The DLLA139P887 Common Rail Injector Nozzle is a high-performance replacement part engineered for Denso common rail systems. Crafted from premium bearing steel, this nozzle is designed to withstand the rigorous demands of modern diesel engines, ensuring durability against high temperature and pressure.

Technically, the "139" in the model name indicates a precise spray angle of 139 degrees, which is critical for the correct combustion geometry in the cylinder. This nozzle is widely used as a replacement component for Denso injectors (such as the 095000-6490 series), which are commonly found in Isuzu 4HK1 and 6HK1 engines. These engines power a variety of heavy-duty applications, including Isuzu trucks and Hitachi excavators. By replacing worn-out nozzles with the DLLA139P887, you can effectively resolve issues like engine knocking, excessive black smoke, and poor fuel economy, restoring your machinery to peak operating condition.

• Exact Flow Matching: Precision-drilled spray holes guarantee the correct fuel flow rate and atomization pattern for Isuzu engines.

• Enhanced Durability: Heat-treated alloy steel construction resists needle wear and nozzle tip erosion, extending service life.

• Improved Fuel Economy: Restores the original spray mist quality, ensuring complete combustion and reducing wasted fuel.

• Stable Performance: Delivers consistent injection pressure, helping to reduce engine vibration and idling noise.

• Cost-Effective: A high-quality aftermarket solution that matches OEM performance standards at a competitive price point.
