Common Diesel Emissions Problems and Solutions from Your Trusted Specialists at Branch Automotive

When it comes to diesel vehicles, emissions are a significant concern both for environmental health and the proper functioning of your vehicle. As the diesel specialists at Branch Automotive in Littleton, CO, we’re here to guide you through common diesel emissions problems and offer reliable solutions.

Understanding Diesel Emissions

Diesel engines are known for efficiency and torque, but they can also produce certain pollutants during fuel combustion. These include nitrogen oxides (NOx), particulate matter (soot), carbon monoxide (CO), and hydrocarbons (HC). Effective emissions systems control these pollutants to meet state and federal regulations.

Common Emissions Problems

  1. Excessive Exhaust Smoke: If you notice your vehicle emitting more smoke than usual, it could indicate incomplete combustion. This can be due to various factors such as a dirty air filter, problems with fuel injectors, or issues with the turbocharger.
  2. Increased NOx Emissions: Elevated levels of nitrogen oxides are harmful to the environment, contributing to smog and acid rain. A malfunctioning EGR (Exhaust Gas Recirculation) valve, which helps reduce NOx, can be a common culprit.
  3. DPF Clogging: The Diesel Particulate Filter is crucial for capturing and mitigating soot. Over time, it can become clogged, leading to increased back pressure, reduced performance, and even engine damage if not addressed.
  4. Faulty Sensors: Modern diesel vehicles rely on many sensors to monitor emissions. A faulty sensor can lead to incorrect data being fed to the vehicle’s computer, causing the engine to run inefficiently.
  5. Ignoring A Check Engine Light: Don’t ignore that light! A check engine light indicates that the engine is not running properly or that there is a concern present in the emissions system. Ignoring a check engine light only makes it worse, because when diesel engines run inefficiently, they make more smoke (soot) for the DPF and other aftertreatment systems to deal with, shortening their lifespan and creating expensive problems.

Solutions Offered by Branch Automotive

At Branch Automotive, we approach each problem with a comprehensive solution:

  1. Thorough Diagnostics: Utilizing our state-of-the-art chassis dynamometer, we can accurately diagnose emission problems by simulating various driving conditions right in our shop. We’re also equipped with the same diagnostic testing equipment that the manufacturer has to provide the most accurate information, operated by the best, specialized diesel technicians in the state.
  2. Regular Maintenance: Preventive maintenance is key. Regularly replacing air filters, fuel filters, getting engine oil services, operating the vehicle as it should be, and ensuring components like the turbocharger are in good working order can prevent many emissions issues.
  3. Emissions Testing and Repair: As one of the few diesel emission testing facilities certified by the state of Colorado, we provide thorough emissions testing and the necessary repairs to keep your vehicle compliant with state regulations.
  4. Sensor and Component Inspection and Replacement: We are well-equipped and trained to inspect and test the modern exhaust systems and, if necessary, replace faulty emissions sensors or components to ensure accurate readings and optimal engine performance.
