If you currently have a diesel vehicle, paying attention to the exhaust system is crucial to ensure the best performance and fuel efficiency. When the exhaust system functions optimally, it can minimize harmful emissions, keeping your vehicle running smoothly and protecting the engine.
Sadly, not all car owners can keep the exhaust system in top shape. Overlooking proper maintenance for the exhaust system allows problems to develop, including poor fuel economy, diminished engine performance, excessive noise, and potential damage to the engine. On top of that, a poorly maintained exhaust system contributes to air pollution. Sadly, it lowers your chances of passing the emission standards, resulting in a hefty penalty.
Routine inspections will go a long way in ensuring the optimal functionality of your diesel vehicle since there are numerous components to keep track of. Being familiar with the essential components may be best if you’re hands-on with your car. You may want to know how to use v band fittings and other components to ensure a head start.
If you want to ensure the exhaust system of your diesel engine functions optimally, here are several insightful tips that’ll serve as your guide to keeping your vehicle efficient at all times.
- Routine Cleaning Of The Engine
Diesel engines usually have a longer lifespan than their gas counterparts, but it’s crucial to provide regular cleaning. If you use your vehicle for long trips, expect dirt and dust to build up on the engine.
As the debris accumulates over time on the different components of your car’s engine, it diminishes its lifespan and affects fuel efficiency. Additionally, if you reside in areas with harsh weather conditions, the engine parts are prone to rapid deterioration due to road salt exposure, intensifying rust and corrosion.
With this in mind, a meticulous cleaning routine for your diesel engine is important. You can check the manual before starting cleaning for advice. However, you most likely need a specialized degreaser, a moist sponge, and an old toothbrush. Allow the engine to cool down before scrubbing, and make sure you use protective gear such as gloves and goggles.
- Closely Monitor The Exhaust System
The exhaust system is a crucial element in the functionality of diesel vehicles. Over the years, the exhaust systems evolved to include components such as diesel particulate filters (DPF) and diesel exhaust fluid (DEF).
Pay close attention to the DPF regeneration as the particles reach the combustion point and eventually turn into carbon dioxide (CO2) and ash. The regeneration process involves three types: passive, active, and forced. If the regeneration happens regularly, it’s best to have your vehicle serviced so an inspection can be performed to determine the cause. Aside from the regeneration, make it a priority to clean the DPF filter regularly to eliminate any lingering particles.
- Timely Replacement Of The Filters
Diesel filters play an important role in the preventive care of your vehicle. A timely replacement is crucial to ensuring your engine receives clean fuel. If the filters are clogged or dirty, the flow to your engine will be limited or disrupted. The diminished flow of fuel will result in poor engine performance.
Sadly, if the filters are severely clogged, the engine might not run properly or even start. Most diesel engines have two fuel filters. The main fuel filter is between the gas tank and the engine, while the second filter is between the transfer pump and fuel injectors.
A replacement may be necessary once your vehicle reaches 10,000 to 15,000 miles, but it’s best to check the recommendation by the manufacturer for your specific model and make. A tip to remember is to replace both primary and secondary fuel filters simultaneously to maximize their lifespan and efficiency.
- Clean The Fuel Injection System
Fuel injectors play an important role in the internal combustion process in diesel vehicles. The vehicle’s computer system regulates every fuel injection to ensure consistent timing and amounts of fuel injected. However, diesel fuel contains particles that steadily build up in the fuel system over time. When you’re unable to keep the fuel injection system clean regularly, it can result in a blockage that leads to poor engine performance, high emissions, and damage to the injectors or other engine components.
When cleaning the fuel injection system, you can use an injector cleaning kit, a fuel injector cleaner, or fuel additives.
If you want to clean the fuel injectors regularly, consider using a diesel fuel cleaner additive. The ideal approach is to add the additive to the fuel tank so it cycles through the engine. Doing this can prevent the buildup of debris or gunk in the fuel injection system of your vehicle.
Final Thoughts
Routine diesel vehicle maintenance will go a long way toward keeping the exhaust system in good shape. Generally, it also benefits the engine and other related systems, especially regarding fuel efficiency and reducing emissions. Following a regular maintenance routine that covers the engine, filters, and fuel injection system ensures your car operates efficiently. You can always keep your diesel vehicle in good shape in the long run.
