It was only 5 - 6 years ago when diesel particulate filters were put on construction equipment to comply with new regulations around emission control. Construction equipment manufacturers modified their designs to include the diesel particulate filters (DPF) as part of the exhaust system and an essential part of the comprehensive emissions control system. The DPF’s purpose is to trap soot and harmful emissions from being released into the atmosphere. Engineers have worked since then to reduce emissions on equipment while also preserving the efficiencies and benefits of a diesel engine. There are different recommendations for frequency of DPF cleaning for construction equipment –it depend son the manufacturer, however we suggest equipment with 4000+ hours should have...
A One Box is a compact assembly that effectively packs all the machinery and exhaust pipes in a small box! Diesel-powered trucks have always functioned as the workhorses in our society for delivering massive amounts of goods between places. As emissions regulations have become stricter and the need for less downtime became continually greater several truck industries came up with a modern diesel aftertreatment system known as the ‘One-Box.’ While meeting the requirements of emissions regulators such as the EPA, the best thing about One Box is that it is a compact assembly that includes all the components in a small box efficiently! One Box - Understanding the Workings of Exhaust System Components To understand the...
As a trucking fleet manager, your vehicles are your pride and joy. Understandably, you want to ensure your vehicles function as per the latest industry standards, starting with the maintenance of diesel particulate filters (DPF) crucial for practicing emission control. In recent times, emission control has become mandated by the law. Health experts and policymakers have noted that diesel-powered motor vehicles produce large amounts of soot, resulting in an increased risk of respiratory and cardiovascular diseases. This observation has established the installation of DPFs in diesel-charged fleets as a requirement all industry personnel is expected to meet. DPFs separate soot particles from the exhaust gas of a diesel engine. In so doing, they prevent deadly diesel emissions from...
DPFs require regular maintenance to function correctly to give you better fuel mileage. While a DPF’s primary purpose is to trap and hold on to damaging particulates, it also needs to get rid of them. In a regeneration process, the DPF exposes the particulates to extremely high temperatures to burn them and turn them into harmless ash. The regeneration process acts as a self-cleaning system with two methods, active and passive regeneration. Passive regeneration occurs when driving at high speeds for an extended amount of time. When diesel vehicles drive short distances while going at slower speeds, the DPF does not get hot enough to create ideal temperatures to burn soot. This issue is common with urban driving and vehicles...
What is DEF? Diesel exhaust fluid (DEF) is a non-hazardous solution, which is 32.5% urea and 67.5% de-ionized water. DEF is not a fuel additive and does not come in contact with diesel. DEF is sprayed into the exhaust stream of diesel vehicles to break down dangerous NOx emissions into harmless nitrogen and water. Getting DEF into the fuel tank can be thousands of dollars to repair and getting diesel into the DEF tank will also be an expensive fix but not as much as DEF into the fuel tank. Ever run into the issue of coolant that has leaked into the DPF which has caused cracking and fouling of the DOC (diesel oxidation catalyst)? This will eventually...
