John Deere is a leading manufacturer of agricultural, construction, and forestry machinery, as well as diesel engines and lawn care equipment. In their diesel engines, they use NOx (Nitrogen Oxides) sensors to monitor and control the emissions of harmful nitrogen oxides. These sensors are essential for meeting strict emission regulations and ensuring optimal engine performance.
The NOx sensor is a part of the Selective Catalytic Reduction (SCR) system, which reduces NOx emissions by injecting a urea-based solution (Diesel Exhaust Fluid or DEF) into the exhaust stream. The NOx sensor measures the concentration of NOx in the exhaust gases before and after the SCR catalyst, allowing the engine control unit (ECU) to adjust the amount of DEF injected to achieve the desired reduction in NOx emissions.
John Deere Original Equipment (OE) NOx sensors are designed and manufactured to meet the specific requirements of John Deere engines. These sensors are built to provide accurate and reliable measurements, ensuring optimal engine performance and compliance with emission regulations.
Here is a list of some John Deere Original Equipment (OE) NOx sensors, their corresponding part numbers, and the engine models they are commonly used in. Please note that this is not an exhaustive list, and the specific NOx sensor required for your John Deere engine may vary depending on the model and year.
