Selective Catalytic Reduction (SCR) is a vital part of the aftertreatment system that reduces harmful emissions and helps your truck meet emissions standards. However, SCR systems can often cause confusion and frustration for truck owners and operators, especially when they experience issues with their performance.
In this article, we will discuss the top SCR maintenance tips for keeping your truck running smoothly and efficiently. Selective Catalytic Reduction (SCR) is an important part of the aftertreatment system that reduces harmful emissions and improves diesel fuel efficiency. However, like any other component, SCRs require regular maintenance to perform at their best. Read on to learn how to maintain your SCR properly and save money in the long run.
How Do SCRs Work?
Selective Catalytic Reduction is an aftertreatment system that reduces nitrogen oxide (NOx) emissions from diesel engines. The system injects diesel exhaust fluid (DEF) into the exhaust stream, which converts NOx into nitrogen and water. The SCR system uses a catalyst to facilitate the chemical reaction that converts NOx into harmless nitrogen and water.
The catalyst is made up of precious metals like platinum and palladium, which can degrade over time due to various factors. Catalyst poisoning is a common issue that can reduce the efficiency of the SCR system and cause increased emissions. To avoid these issues, it's important to properly maintain your SCR system with a regular inspection and cleaning process.
Regular maintenance can also prevent other issues that can impact SCR performance, such as thermal stress, clogging, and leaks. By following our maintenance tips, you can help ensure that your SCR system is operating efficiently and reducing harmful emissions as intended.
Common Selective Catalytic Reduction Issues in Heavy-Duty Trucks
While SCRs are designed to last for thousands of miles, they can experience issues that impact their performance. Here are some common issues that truck owners and operators may encounter with their SCR systems:
As mentioned earlier, catalyst poisoning is a common issue that can reduce the efficiency of the SCR system. This can be caused by exposure to contaminants like oil, coolant, and fuel, or by using the wrong type of DEF.
SCR systems can also experience thermal stress due to extreme temperature fluctuations, which can cause catalyst deactivation and reduce system efficiency.
SCR systems can become clogged over time due to the accumulation of soot and other particulate matter, which can reduce system efficiency and increase emissions.
SCR systems can also develop leaks over time, which can impact system performance and lead to costly repairs.
To avoid these common issues, it's important to follow our maintenance tips and schedule regular inspections and cleaning. By properly maintaining your SCR system, you can ensure that it continues to reduce harmful emissions and operates at peak efficiency.
SCR Maintenance Tips
Proper maintenance is crucial for keeping your selective catalytic reduction system running efficiently and reducing harmful emissions. Here are some maintenance tips to add to your preventative maintenance schedule:
Using high-quality DEF is crucial for ensuring that your SCR system operates efficiently. Make sure to use DEF that meets the manufacturer's specifications and avoid using old or contaminated DEF. Regularly check levels and refill the DEF tank as needed. Running out of DEF can cause the system to shut down and lead to costly repairs.
Regular Inspections & Cleaning
Regularly inspecting and cleaning the SCR system can help prevent issues like clogging and reduce the risk of costly repairs. Make sure to follow the manufacturer's recommendations for cleaning and inspecting the system. Also, regularly inspect the SCR system for leaks, and address any leaks promptly to prevent system damage.
Following a Maintenance Schedule
Following the manufacturer's recommended maintenance schedule is crucial for ensuring that your aftertreatment system, including the SCR, operates efficiently. This can help prevent issues and reduce the risk of costly repairs. In addition to the above maintenance tips, it's important to include the aftertreatment system in your preventative maintenance schedule.
This can include regular inspections and cleaning of the diesel particulate filter (DPF) and other components of the aftertreatment system. By properly maintaining your aftertreatment system, you can help ensure that your truck runs efficiently and meets emissions standards. By adding maintenance to your preventative maintenance schedule, you can help ensure that your SCR system operates at peak efficiency and reduces harmful emissions as intended.
