Denso DLLA138P920 Common Rail Injector Nozzle

The DLLA138P920 is a high-pressure common rail injector nozzle manufactured to OEM specifications for Denso fuel injection systems. It features a 6-hole nozzle configuration with a 138-degree spray angle, constructed from high-speed steel with DLC (Diamond-Like Carbon) coating on the needle for enhanced durability and wear resistance under extreme injection pressures up to 2100 bar. This nozzle component is the critical wear part within the injector assembly 095000-6140 (also referenced as 6261-11-3200 and nozzle holder 093400-9200). It is engineered for precise fuel atomization and metering in heavy-duty off-highway diesel engines. Primary application includes Komatsu SAA6D140E-5 and SAA6D170 engines powering hydraulic excavators, dump trucks, and wheel loaders. Dimensional tolerances and flow characteristics are calibrated to match OEM calibration codes (e.g., BEGWVDJTP) ensuring exact spray pattern and injection quantity.
