AGGREGATES MANAGER / December 2017 19 Maintaining diesel particulate filters Diesel particulate filters trap particulate matter that exists in the exhaust stream, much of which is cleaned during regular operating conditions through passive regeneration. However, over time, the filter reaches a point where it needs to be cleaned by raising exhaust tem- peratures, otherwise known as active regeneration. An active regeneration cycle will happen automatically without operator action. It shouldn't affect normal oper- ation and will only be noticeable by an indicator light on the dashboard when it is in process. It is also important to note that users should not override an active regeneration cycle when it is already in process. "One of the main takeaways for operators is to let the system work, which includes letting it run through necessary regeneration cycles" Cawelti adds. "When left to operate under normal conditions, the system will run as it should." Leverage existing experience As always, one of the biggest things operators can do to ensure a smooth engine operating experience is to keep lines of communications open. "Talk to your OEM and to the engine manu- facturer representatives. Learn about what's there and what you can and cannot do," Wood says. Becoming informed about the new technology, whether through conver- sations with engine manufacturers or product research, will generally ease the transition into Tier 4. In fact, many of these technologies have been imple- mented in the on-highway market for some time, so users may already have experience with Tier 4 technology from driving their truck, for example. "It is also important for operators to understand that our application engineering team works hand-in-hand with OEM equipment manufacturers to ensure that Tier 4 installations are as seamless as possible for end-users," Cawelti explains. "We are here to make sure everything under the hood operates as it should for you." When it comes to operating a Tier 4 piece of equipment, capitalize on your experience. "Work your machine like it wants to be worked. Maintain it by keeping proper service intervals, which are defined for the different systems on the engine, and use the right fluids," Wood said. "If you do that, we are confident you will have a positive experience."
