Dorman 904-7915 Hydrocarbon Injector Nozzle
Dorman 904-7915 Hydrocarbon Injector Nozzle
Dorman 904-7915 is a diesel hydrocarbon injector nozzle that restores dosing function in the emissions system. It injects fuel into the exhaust stream during regeneration cycles to help remove carbon buildup from the diesel particulate filter.
Built with a metal body, threaded M12-1.5 fuel inlet, and bolt-on mounting, this nozzle is a direct service part for diesel emissions repair. It is a practical replacement for vehicles needing a hydrocarbon injector nozzle for DPF regeneration and exhaust aftertreatment performance.
Key Features
- Hydrocarbon injector nozzle for diesel emissions systems
- Supports exhaust-stream fuel dosing during regeneration cycles
- Metal construction for service replacement use
- Threaded inlet with M12-1.5 fuel inlet threading
- Bolt-on mounting with 2 mounting holes
- Gasket and mounting hardware included
- Cross-reference part number: 21407621
Detailed Description
This Dorman hydrocarbon injector nozzle is used in diesel aftertreatment systems to deliver fuel into the exhaust stream when the regeneration process is active. That dosing action helps the system burn off accumulated soot in the diesel particulate filter, supporting proper emissions-system operation. For diesel applications that call for Dorman 904-7915, this replacement nozzle provides the correct threaded inlet, mounting style, and included gasket for service work. It is a focused repair part for vehicles such as Volvo XC90 and Volvo S60 applications where the hydrocarbon injector nozzle is part of the emissions control system.
What It Helps Fix
- Faults related to failed exhaust fuel dosing
- Restricted DPF regeneration caused by injector nozzle wear
- Carbon buildup in the diesel particulate filter
- Emissions-system performance issues tied to a damaged nozzle
- Leaks at the injector nozzle mounting point
Installation Notes and Tips
Verify the fuel inlet threading, mounting hole count, and overall length before installation. Clean the mounting surface thoroughly and replace the gasket during service to help maintain a proper seal. Confirm the vehicle’s diesel emissions system uses a threaded, bolt-on hydrocarbon injector nozzle before ordering Dorman 904-7915.
Quality Assurance
Dorman manufactures replacement emissions components for service applications where restoring original function matters. This part is built as a direct replacement style nozzle for diesel exhaust dosing systems.
