Key Features & Benefits
Common Rail Precision Engineering
The 6218-11-3101 is a common rail diesel fuel injector that operates within Komatsu's high-pressure electronic fuel injection system. It delivers fuel into the combustion chamber at precisely controlled timing and pressure, ensuring optimal power output and fuel efficiency across all operating conditions.
Denso OEM Quality
Manufactured by Denso, a world-leading supplier of automotive and heavy equipment fuel injection systems, this injector meets the highest standards of precision engineering and quality control.
Electronically Controlled Fuel Metering
The injector features electronically controlled fuel metering, regulated by the engine's ECU to optimize injection timing, pressure, and volume for varying load conditions. This ensures the engine delivers the right amount of fuel whether the machine is idling, dozing, or under heavy load.
Superior Atomization for Cleaner Combustion
The injector's advanced nozzle design (compatible with DLLA143P761, BLLA143P761-J, and ALLA143P761-J nozzles) promotes superior fuel atomization, enabling cleaner, more complete fuel burning. This reduces emissions, improves fuel efficiency, and lowers operating costs.
Durable Heavy-Duty Construction
Built with high-strength materials and precision-machined components, the assembly withstands the extreme pressures, temperatures, and vibrations of heavy-duty bulldozer operations, resisting wear, corrosion, and fatigue.
OEM Compatibility & Seamless Fitment
As a genuine-grade Komatsu/Denso replacement part, the 6218-11-3101 injector matches the exact specifications of the factory-installed component, guaranteeing seamless fitment and reliable performance.
