Emissions System Repair

Emissions System Repair

We specialize in mobile emissions system repair services for heavy equipment, ensuring your machinery meets regulatory standards and operates at peak efficiency. Diesel engines used in heavy equipment are subject to stringent emissions regulations designed to reduce harmful pollutants. A malfunctioning emissions system can lead to performance issues, excessive emissions, and regulatory penalties. Our experienced mechanics offer comprehensive diagnostics, repairs, and maintenance for your emissions system, helping you stay compliant while minimizing downtime.

The Importance of Emissions Systems in Heavy Equipment

Emissions systems play a critical role in reducing the pollutants produced by diesel engines, including nitrogen oxides (NOx), particulate matter (PM), hydrocarbons, and carbon monoxide (CO). These systems are designed to filter, convert, or reduce harmful exhaust gases before they are released into the atmosphere. Properly functioning emissions systems not only help you meet environmental regulations but also enhance the fuel efficiency and overall performance of your equipment. When these systems malfunction, your engine may experience reduced power, poor fuel economy, and increased emissions, all of which can lead to costly fines and downtime.

Comprehensive Emissions System Services

We provide a wide range of services to diagnose, repair, and maintain emissions systems in heavy equipment. Our skilled technicians are trained to work on the latest emissions technologies and are equipped to handle a variety of components and systems, including:

• Diesel Particulate Filter (DPF) Cleaning & Replacement: The DPF is responsible for trapping particulate matter (soot) from the exhaust, preventing it from being released into the atmosphere. Over time, the DPF can become clogged with ash and soot, causing reduced engine performance and increased emissions. We offer professional DPF cleaning services using specialized equipment to remove built-up ash and restore proper airflow. If the filter is too damaged or clogged, we provide DPF replacement services.
• Selective Catalytic Reduction (SCR) System Repair: The SCR system is essential for reducing nitrogen oxide (NOx) emissions by injecting diesel exhaust fluid (DEF) into the exhaust stream, converting NOx into harmless nitrogen and water. Malfunctions in the SCR system can result in excessive emissions and trigger fault codes or warning lights. We diagnose and repair SCR issues, including DEF injector problems, catalyst damage, and sensor failures, to ensure your equipment meets NOx reduction targets.
• Exhaust Gas Recirculation (EGR) System Repair: The EGR system helps reduce NOx emissions by recirculating a portion of the exhaust gas back into the engine’s combustion chamber. This lowers the combustion temperature, which in turn reduces NOx formation. Over time, EGR valves and coolers can become clogged with carbon deposits, leading to reduced engine performance and increased emissions. We clean or replace EGR valves and coolers to restore proper functionality.
• Catalytic Converter Repair & Replacement: The catalytic converter is responsible for reducing harmful hydrocarbons (HC) and carbon monoxide (CO) emissions. When the catalytic converter becomes damaged or clogged, it can lead to poor exhaust flow, reduced fuel efficiency, and failed emissions tests. Our technicians can diagnose and repair catalytic converter issues, and if necessary, replace the unit to restore emissions control.
• DEF System Maintenance: Diesel Exhaust Fluid (DEF) is crucial for the proper operation of the SCR system. Low-quality DEF or improper handling can lead to contamination, injector clogging, or sensor failure. We provide DEF system maintenance, including fluid level checks, sensor calibration, and injector cleaning, to keep your SCR system functioning properly.
• Oxygen and NOx Sensor Replacement: Sensors play a vital role in monitoring exhaust gases and ensuring the emissions system operates efficiently. Faulty sensors can result in incorrect readings, leading to increased emissions or engine performance issues. We diagnose and replace faulty oxygen and NOx sensors to ensure accurate readings and proper emissions control.
• Emissions System Diagnostics: We use advanced diagnostic tools to identify issues within your emissions system, whether it’s a blocked filter, a failing sensor, or a malfunctioning SCR system. Our thorough diagnostic process allows us to pinpoint the exact cause of the problem, minimizing downtime and ensuring a precise, effective repair.

Common Emissions System Problems We Address

Emissions systems are complex, and over time, components can wear out or fail due to heavy use, contamination, or improper maintenance. Below are some of the most common emissions system problems we address:

• DPF Clogging: A clogged DPF can cause a loss of power, increased fuel consumption, and trigger fault codes or warning lights. We clean or replace DPFs to restore proper exhaust flow and reduce emissions.
• SCR Malfunction: Problems with the SCR system, such as DEF contamination, injector issues, or catalyst failure, can lead to excessive NOx emissions. We diagnose and repair these problems to ensure your equipment meets emissions standards.
• EGR Valve Failure: Clogged or faulty EGR valves can cause poor engine performance, rough idling, and increased emissions. We clean or replace EGR valves and coolers to restore functionality and improve fuel efficiency.
• Sensor Failures: Faulty oxygen or NOx sensors can lead to incorrect emissions readings, resulting in higher emissions and engine performance issues. We replace malfunctioning sensors to ensure accurate emissions control.
• Catalytic Converter Clogging: A clogged or damaged catalytic converter can reduce exhaust flow, causing poor fuel economy and increased emissions. We repair or replace catalytic converters to restore emissions control and engine efficiency.

Our Emissions System Repair Process

Our emissions system repair process begins with a comprehensive diagnostic assessment of your equipment’s emissions system. We use advanced diagnostic tools to identify the root cause of the issue, whether it’s a clogged filter, a faulty sensor, or a malfunctioning SCR system. Once we’ve identified the problem, we provide a detailed estimate of the necessary repairs, including parts and labor costs.

Next, our certified technicians perform the repair or replacement, addressing any malfunctioning components such as the DPF, EGR valve, catalytic converter, or sensors. We use only high-quality, OEM-compliant parts to ensure long-lasting, reliable repairs that restore your emissions system to peak performance.

After the repairs are completed, we perform extensive testing to verify that your emissions system is operating correctly and that your equipment meets all emissions standards. We ensure that all fault codes are cleared and that your machinery is running efficiently before returning it to service.

To help prevent future issues, we also offer preventive maintenance services, including regular DPF cleaning, sensor inspections, and fluid checks. This proactive approach helps you avoid costly breakdowns, reduce emissions, and extend the life of your emissions system.
