Fleets that operate, maintain, and repair commercial trucks have many expenses. One expense that consistently ranks in the top is diesel emissions systems. Learn how to contain emissions costs.
When diesel emissions systems were first introduced in 2007 and updated in 2010, vehicle owners relied on the manufacturers’ recommendations. Their costs skyrocketed and this led to a lot of frustration on the part of vehicle owners, especially in the commercial fleet business.
Changing Maintenance Practices to Lower Costs
“…Batesville, too, is unhitching itself from the OEM recommendations on exhaust maintenance. After investing big money in a DPF cleaning machine, he says, his technicians discovered that if they waited until 300,000 or 400,000 miles to pull the filter and clean it, as recommended by the OEMs, carbon was packed so tightly into the unit that the entire exercise was pointless. Today, he says, his technicians routinely pull DPFs every 100,000 miles for cleanings, which has helped with both maintenance costs and fleet fuel economy averages.”
Addressing Upstream Issues
Many fleets make the mistake of treating the exhaust system as if it’s a self-contained entity that is somehow separate from the rest of the engine. It is not, rather issues with the components in the diesel emissions system are often just the symptom of a problem, not the root cause. Throwing replacement parts at the symptom never addresses the root cause and this strategy leads to much higher repair and maintenance costs in the long term.
A Comprehensive Maintenance Plan
At the Diesel Emissions Service repair shops, we have been performing emissions cleanings and repairs for 15+ years, and our experience agrees with what these fleet managers have discovered.
DES recommends that DPF filters be cleaned yearly or every 75-100k miles. This regular cleaning interval of the diesel particulate filter, which is a serviceable filter and does not need to be replaced every time, keeps the filter from being clogged with soot and ash triggering a fault code putting the vehicle into a derate or limp mode. It will also ensure that the volumetric efficiency of the DPF will keep back pressure to a minimum.
Education is an Important Part of Lowering Emissions Costs
