EGR System: Ensuring Efficient Combustion and Reduced Emissions

Understanding the Role of EGR in Diesel Engines

The EGR system in diesel engines is designed to reduce nitrogen oxide (NOx) emissions, which are known to contribute to air pollution. The EGR system recirculates a portion of the exhaust gases back into the engine's combustion chambers. This reduces combustion temperatures and, as a result, lowers NOx emissions.

Mountain Pacific Mechanical specializes in repairing and maintaining EGR systems to ensure your diesel trucks operate optimally. We can diagnose and resolve issues like clogged EGR valves and cooler leaks and perform critical maintenance services.

Expert EGR Valve Cleaning and Replacement

Over time, EGR valves can become clogged with soot and carbon deposits, leading to reduced performance and fuel efficiency. At Mountain Pacific Mechanical, our skilled technicians provide professional EGR valve cleaning services to ensure your engine’s emissions remain within regulation limits. In cases where the valve cannot be salvaged, we offer EGR valve replacements using high-quality parts designed to last.

DPF Maintenance: Keeping Your Diesel Particulate Filter in Peak Condition

The Importance of a Functional DPF

Diesel Particulate Filters (DPFs) are crucial for trapping soot particles and preventing them from being released into the atmosphere. A clogged or damaged DPF can lead to decreased engine performance and increased fuel consumption and can cause your vehicle to fail emissions tests.

At Mountain Pacific Mechanical, we understand the intricacies of DPF systems. Our advanced diagnostic tools and equipment allow us to detect any issues and perform necessary repairs or replacements efficiently.

Comprehensive DPF Cleaning Services

Regular DPF cleaning is essential for your filter's longevity and proper functioning. Our technicians at Mountain Pacific Mechanical use industry-leading techniques, such as forced regeneration and pneumatic cleaning, to effectively remove soot and ash build-up from your DPF. This extends the filter's life, improves fuel efficiency, and reduces the risk of unexpected breakdowns.
