The DEF/Urea Dosing Nozzle is a precision injector component designed for modern BS6 diesel vehicles equipped with a urea-based Selective Catalytic Reduction (SCR) emission control system. Its primary function is to accurately spray Diesel Exhaust Fluid (DEF), also called AdBlue or urea solution, into the exhaust stream ahead of the SCR catalyst. This injected fluid chemically reacts with nitrogen oxides (NOx) in the exhaust, converting them into harmless nitrogen and water vapor to meet stringent BS6 emission standards.

Key Features

• Precision Injection: Delivers controlled amounts of DEF/urea into the exhaust for optimal NOx reduction.

• Durable Construction: Made from heat-resistant, corrosion-protected materials to withstand high exhaust temperatures and harsh operating conditions.

• Direct Replacement: OEM-equivalent fit for Hyundai and Kia SCR systems that require 296302U000 dosing nozzle.

• Emission Compliance: Supports BS6/BS6 Phase II statutory emission norms by enabling SCR functionality.

• Compact Design: Engineered to integrate seamlessly into the vehicle’s existing exhaust treatment assembly without modification.

Functionality

• Works in conjunction with the SCR catalyst and NOx sensors to detect exhaust composition and adjust dosing precisely for efficient NOx conversion.

• Interfaces with the vehicle’s ECU to ensure injection timing and volume match emission control requirements.

• Acts as a critical component in reducing harmful pollutants while maximizing diesel engine performance and efficiency.

Common Fault Symptoms (When Failing)

• DEF System Warning: Dashboard alert indicating urea/DEF system malfunction.

• Reduced Performance: In some cases, the engine may enter reduced-power mode due to SCR errors.

• Leakage: Urea fluid leaks around the nozzle seal or injector body, leading to crystallization and reduced performance.

• Error Codes: Emission-related fault codes detected on diagnostic scanning (e.g., NOx sensor circuit, dosing circuit malfunction).

• Crystallization Buildup: Dried urea residues forming around the injector tip or piping, affecting spray pattern and performance.

Typical Fault Causes

• Nozzle clogging due to contaminated DEF/urea solution.

• Cracked or damaged injector body or seals.

• Faulty wiring or electrical connector to the dosing unit.

• Crystallized deposits blocking the dosing path.

• Wear and tear from prolonged high-temperature exhaust exposure urea injector pipe leak or damage
