Understanding the Components of the SCR System in Peterbilt Trucks
The selective catalytic reduction (SCR) system is a critical component of modern diesel trucks. It is used to reduce harmful emissions produced by diesel engines. This system is used in Peterbilt trucks to ensure they meet stringent emission standards set by the government. The SCR system consists of several components, including an engine-mounted diesel oxidation catalyst, a downstream diesel particulate filter, and a urea-based reductant injection system.
The diesel oxidation catalyst helps to break down nitrogen oxides into less harmful compounds. It does this by combining nitrogen oxides with oxygen and other elements in the exhaust stream. The downstream diesel particulate filter traps soot and other particles from the exhaust stream, which helps to reduce air pollution.
The urea-based reductant injection system is the most important component of the SCR system. This system injects urea solution into the exhaust stream before it enters the diesel oxidation catalyst and particulate filter. The urea solution reacts with nitrogen oxide molecules in the exhaust stream to form nitrogen and water vapor, which are much less harmful than nitrogen oxide molecules.
In order for these components to work together properly, they must be carefully calibrated and monitored. Peterbilt’s SCR system is designed to self-monitor its performance using sensors that detect changes in engine performance or emissions levels. If any issues are detected, an alert will be sent to the truck’s on-board computer, which will then take corrective action if necessary.
Overall, understanding how each component of an SCR system works together is essential for ensuring that your Peterbilt truck meets emission requirements and keeps running smoothly over time. By familiarizing yourself with how each component works, you can ensure that your truck is operating at its optimal level and helping keep your community healthy by reducing air pollution from diesel engines.
