SUnderstanding EGR Systems

EGR systems play a vital role in reducing harmful emissions produced by diesel engines. They recirculate a portion of exhaust gases back into the engine, reducing nitrogen oxide (NOx) emissions. However, EGR systems can experience issues such as clogging, carbon buildup, or malfunctioning valves, leading to decreased engine performance and increased emissions. At Diesel Worx, we have a deep understanding of EGR systems and can diagnose and repair any problems that arise.

Diesel Particulate Filter (DPF) Operation

DPF systems are designed to trap and remove particulate matter from diesel engine exhaust. Over time, the filter can become clogged with soot and ash, impacting engine performance and emissions. At Diesel Worx, we have in-depth knowledge of DPF systems and their operation. Our technicians can accurately assess the condition of your DPF and provide efficient repair solutions, whether it's through cleaning or replacement, to ensure optimal performance and compliance.

Troubleshooting EGR and DPF Issues

Diagnosing EGR and DPF issues requires specialized knowledge and diagnostic tools. Our experienced technicians at Diesel Worx are skilled in troubleshooting and pinpointing problems within these complex systems. We utilize advanced diagnostic equipment to identify issues such as valve malfunctions, sensor failures, clogged filters, or exhaust leaks. With our expertise, we can quickly and accurately diagnose the root cause of any EGR or DPF problem.
