2.Product Introduction

The Cummins Urea Doser Pump Injector Nozzle 1205750-T39H0/5309343 is a component of the Cummins SCR (Selective Catalytic Reduction) system used in diesel engines to reduce nitrogen oxide emissions. The Urea Doser Pump Injector Nozzle is responsible for injecting urea, also known as DEF (Diesel Exhaust Fluid), into the exhaust system to convert nitrogen oxide into harmless nitrogen gas and water vapor.

The nozzle is mounted in the exhaust system and is fed by the dosing pump, which delivers a precise amount of DEF into the exhaust stream. When the DEF is injected into the exhaust gas, it reacts with the nitrogen oxide and converts it into nitrogen gas and water vapor, which are harmless to the environment.

The Urea Doser Pump Injector Nozzle is designed to atomize the DEF into fine droplets, which helps to ensure complete mixing with the exhaust gas for maximum conversion efficiency. It is a critical component of the SCR system and must be properly maintained to ensure reliable operation and maximum emissions reduction.
