FUEL EFFICIENCY AND OPTIMAL DIESEL ENGINE OUTPUT WITH REGULAR EMISSIONS AFTERTREATMENT MAINTENANCE

MAINTAIN OR IMPROVE DIESEL FUEL EFFICIENCY AND DIESEL ENGINE OUTPUT WITH EMISSIONS SYSTEM MAINTENANCE

YOUR DIESEL TRUCK’S EXHAUST AFTERTREATMENT SYSTEM AND WHAT THE DOC, THE DPF, AND THE SCR HAVE TO DO ABOUT IT

Your heavy duty pickup diesel engine’s aftertreatment system is what Clorox bleach is to a black coffee spill on a white kitchen towel, or what iodine is to a fresh finger cut. It’s the harmful exhaust gas cleaner, killer, remover, and antiseptic. Your exhaust emissions aftertreatment system reduces harmful diesel exhaust emissions and cleans, or removes, pollutant gases from the truck’s exhaust. The aftertreatment process includes filters, catalysts, sensors and other devices to ensure the engine meets emission standards. Exhaust emission gases flow from the exhaust side of the turbo, through the exhaust piping, and downstream through the filters and catalysts of the aftertreatment system.

Unburnt fuel that is emitted from the diesel engine contains emissions that carry particulate matter. Diesel particulate matter is the array of small particles that are composed of solid elemental carbon cores which have the likes of organic carbon compounds such as polyaromatic hydrocarbons adhering to their surfaces. Sulphates and heavy metals can also be contained within diesel particulate matter.

Modern diesel engines operate with exhaust aftertreatment systems which remove nearly all of the particulate matter from the exhaust flow, reducing it to the harmless elements of water and oxygen. Keeping your diesel truck engine’s emissions system optimally operating is important, both for the environment as well as for the fuel efficiency of your diesel truck. Without keeping up with the recommended, regularly scheduled maintenance of the emissions aftertreatment system, your diesel engine will be prone to poor performance, poor fuel efficiency, and the potential failure of aftertreatment components as well as other diesel engine related components.

DOC, DPF & SCR — EXHAUST EMISSIONS AFTERTREATMENT COMPONENTS

Heavy duty diesel pickup trucks use an assortment of exhaust aftertreatment devices, including Diesel Oxidation Catalysts (DOC), Diesel Particulate Filters (DPF) and Selective Catalytic Reduction (SCR) catalysts. These diesel truck aftertreatment devices use physical mechanisms and chemical reactions to remove nearly all particulates and harmful gases.

DOC, DPF & SCR MAINTENANCE

With regular operation of the diesel engine, over time, the DOC, the DPF and the SCR catalyst can become clogged. Keeping these components in efficient working order by adhering to the manufacturer recommended maintenance schedules is vital to their successful execution of the pollutant removal tasks they were designed to accomplish. The big bonus to keeping these in good working order is the diesel engine’s power performance and fuel efficiency that is maintained as a result.

Cummins Automotive & Diesel Service can quickly locate each device and service them accordingly. Without routine maintenance, substantial blockage builds up and can cause irreparable damage to the exhaust system, resulting in high repair costs, unscheduled downtime, and increased pollution released into the environment as well as reduced diesel engine power performance and fuel efficiency.
