Diesel engines are prevalent among heavy-duty truck drivers and people related to the automobile industry. The machines offer top-notch efficiency and safety with longer engine life under heavy loads, constant trips, and extreme road conditions. With the advancement of the technologies, the developers kept adding one after one upgrades to the primary structure to make them even more sustainable. One of the essential addition to the diesel parts is the diesel particulate filters. Here in this article, we will be discussing the important points you need to know about diesel particulate filters.
Diesel particulate filters
Diesel particulate filters burn out the excess soot article or carbon dust either passively or actively from the diesel engine or the exhaust vent. Passively, it will use the catalysts to burn the soot. The active process will use the heat or burner to attain the combustion temperature for the soot particles. A wall-flow diesel particulate filter can remove up to eighty-five percent coal particulates on average. But, it will sometimes remove a hundred percent particulates if the valves are freshly cleaned or new. The diesel engines having diesel particulate filters have a more contemporary design that makes the machines run with elevated exhaust temperatures, and the injectors become full of fuel. Then the catalyst element will activate the soot burning process with the increased temperature. The process is known as the particulate filter regeneration processing.
Particulate and filter efficiency
Several engines produce different types of particulates like soot and unburnt fuel. The engine design, safety protocol, engine age, usage, and emission protocols may vary the particulate formation. The four-stroke engines have a newer design and produce less particulate than the two stroke engines. It also depends on the type of diesel you use. The fuels with more sulfur will produce more sulfur than those with less sulfur and more hydrocarbons ratios ( a compound consisting of hydrogen, carbon, and oxygen). A diesel particulate filter can eliminate particulates measuring as small as 0.1 Millimeter to less.
The DPF filters are essential for our environmental pollution elimination because the soot particles can eliminate in the environment and cause disasters like global warming and drought. Thousands of people are suffering from severe and several respiratory diseases due to particulate ingestion. A compatible DPF filter can help your car run smoothly for years, and it is essential to keep up with good health.
Wall flow DPF
The cordierite DPF filters are the most common variety of the particulate filters. The cordierite is a catalyst that you will also find in the core as a support material. These filters are the best filter choice when it comes to cost efficiency and high performance. Cordierite filters also have a thermal packaging that helps to make the engine design fuel-efficient and straightforward. The most common disadvantage of the wall-flow DPF is it has a shallow melting point. The low melting point causes the filters to meltdown during the regeneration process.
Some other popular types of DPF, like the ceramic fiber filter, the silicon carbide wall-flow filter, metal fiber flow filter, and more, are used.
You have to continuously check the filters for trapped soot particulate and remove it to keep the chamber clean. In 2011 Ford had to recall more than thirty-seven thousand Ford trucks to settle the interior fire issues. The investigation revealed that the firelight up was due to the excess heat, the unfit DPF, and low maintenance. So, keep the right eye on your DPF before It becomes a significant safety issue.
