How does an EGR system work? 

Your EGR system is a complex exhaust recirculation methodology designed to limit the production of nitrogen oxides. By recirculating gas into your combustion chamber, the operating temperature of your engine drops. This results in a reduced nitrogen oxide count and, as such, lessens your engine’s impact on the environment. 

How does this work in a mechanical sense, you may ask? Well, rather than allowing all of your exhaust to escape, some of it is diverted using your engine’s EGR valve. This diverted exhaust is then sent through an air cooler and is then allowed to enter your combustion chamber. This cooled air drops your operating temperature. 

Stuck or Leaking EGR Valves

Although EGR systems are great for the environment and are generally quite durable, they can still malfunction. The most common EGR problem is a stuck EGR valve. When your EGR valve malfunctions, the system is no longer able to regulate how much exhaust enters your combustion chamber, and as such, all of it tries to enter. This snuffs out the presence of oxygen and causes an incredibly rough ride. Common symptoms include constant stalling and extremely poor performance. 

DPF Services

Your Diesel Particulate Filter (DPF) is responsible for removing soot from your exhaust. This filter is designed to lessen your truck’s impact on the environment, and although it generally does a good job, these filters can get clogged a cause a wide array of problems. Since the ability of your DPF to absorb soot is finite, and replacing them isn’t cheap, they often need to be cleaned. Here at IBEX Diesel Repair, we’ll use compressed air to clean your DPF filter and return it to its factory condition.
