The stack on a semi truck is a type of exhaust system consisting of vertical pipes with a rounded end that protrude from the back of the truck. The purpose of the stack is to provide an efficient way to expel fumes and other pollutants away from the driver and passengers, as well as reducing noise levels when driving. The stack also has an aesthetic appeal, often giving semi trucks a unique look.
The stack is mounted on brackets that are welded onto the frame of the truck, and consists of several sections of pipe which are connected together. The front section is called the “header” or “downpipe” and includes a muffler which dampens exhaust noise, while the remaining sections are referred to as “stacks” or “risers”. Depending on the size and type of engine in the truck, there may be anywhere from one to four stacks.
The length and diameter of each stack varies depending on what type of engine is installed in the truck. Generally speaking, larger engines will require longer stacks in order to ensure that fumes and other pollutants are expelled properly away from the cab. Additionally, some stacks may be equipped with spark arrestors which help reduce fire hazards by cutting off sparks created by burning fuel.
Maintenance
In order for semi trucks to remain safe and efficient it’s important that their stacks be regularly inspected for signs of wear or damage. If any rust or corrosion is found, it should be repaired immediately or replaced if necessary. Additionally, it’s important for drivers to check their stacks for blockages caused by debris such as leaves or twigs which can impede exhaust flow.
