Do Semi Trucks Have Catalytic Converters?

Trucker CB Radio Talk
 

Whether you have been driving big rigs for many years, or you’re just beginning your journey driving semi trucks, you may have wondered, “Do semi trucks have catalytic converters?” In short— yes, they do! In the following guide, we’ll explain the elements of a semi truck catalytic converter and why having one that functions properly is important for smooth drives, no matter where the road takes you. 

 

Semi Truck Catalytic Converters

As your engine runs and utilizes fuel throughout southern Florida, the combustion in the engine remains incomplete, meaning extraneous byproducts are left behind as a result of the reaction. Diesel vehicles and semi trucks actually produce more of these byproducts than average cars, so a catalytic converter is necessary to reduce those harmful emissions produced as your semi truck runs. To reduce emissions, semi truck catalytic converters have two main components: 

Diesel Oxidation Catalyst (DOC)

  • These precious metals are the first step in the after-treatment of byproducts created by your engine. As the name implies, they help to catalyze the oxidation of the harmful byproducts. 

Diesel Particulate Filter (DPF)

  • This filter is the second step in the system. It’s a wall-flow filter that traps any remaining particles of soot that the DOC elements do not convert.
