Truck EGR & DPF Services in Crestview, FL

What is the EGR System and Why is it Important?

The EGR system is a pollution control device that reduces the amount of nitrogen oxides (NOx) emitted by a diesel engine. The system recirculates a portion of the engine's exhaust gas back into the intake, which lowers the combustion temperature and reduces the formation of NOx. The EGR system is an important component in the diesel engine's emissions control system, and it must function properly for the engine to pass emissions tests and meet emissions standards.

Signs of EGR System Issues

There are a few signs that a vehicle's EGR system may not be functioning properly. One indication is a decrease in engine power or performance. The EGR system can become clogged or malfunction, causing a restriction in the exhaust system which can negatively impact engine performance. Another indication of a problem with the EGR system is an illuminated check engine light. This can indicate a malfunction with the system, and it will require diagnostic testing to determine the exact issue.

The Role of the Diesel Particulate Filter (DPF)

Another critical component of a diesel engine's emissions control system is the diesel particulate filter (DPF). The DPF is a filter that captures soot and other particulate matter from the exhaust gas before it is released into the atmosphere. Over time, the DPF can become clogged with soot, which can lead to decreased engine performance and even damage to the engine if not addressed.

Signs of DPF Issues

There are several signs that a vehicle's DPF may not be functioning properly. One indication is a decrease in engine power or performance, similar to EGR system issues. Another indication is an illuminated check engine light and increased exhaust emissions. Excessive soot buildup can also cause the DPF to overheat and potentially damage the filter itself. One of the biggest is the DPF constantly entering its regeneration mode, wherein it burns off the accumulated soot. Keep in mind that the burned-off soot is still present within the system, it’s just not directly present on the filter itself; as such, repeated regenerations can result in a build-up of this waste byproduct that can block the DPF and cause more regenerations than normal. While a regular process, if this regeneration function happens constantly, this is definitely a sign that your DPF needs some maintenance.

DPF Repair and Maintenance Services
