FAQ

1. What is the difference between the 093400-6910 and the DLLA157P691?
The number 093400-6910 is the DENSO stock/OEM part number for the complete nozzle, while DLLA157P691 is the specific nozzle code that defines its hydraulic characteristics (spray angle and flow rate). Both refer to the same physical component.

2. How do I install this injector nozzle correctly?
Installation should be performed by a qualified technician. Key steps include cleaning the injector body bore, lubricating the nozzle with clean diesel fuel, and tightening to the manufacturer’s specified torque. It is critical to replace the nozzle retaining nut and any copper washers to prevent leakage and ensure proper operation.

3. What maintenance is required for this fuel injector nozzle?
The nozzle itself is a non-serviceable wear item. However, to maximize its lifespan, ensure the entire fuel system is clean. Regularly replace fuel filters and use high-quality diesel fuel. If you experience symptoms like rough idling, black smoke, or poor fuel economy, the nozzle should be tested and replaced if necessary.
