вЂњBy far the biggest issue we see is transfer containers not being cleaned of other fluids,вЂќ says Miller. Here are the top three ways DEF gets contaminated. вЂњAftertreatment systems are very robust, but only if the DEF fluid is clean and uncontaminated.вЂќ вЂњWe are approximately seven years into using aftertreatment with DEF systems and we still see issues,вЂќ says Miller.

DEF proper handling and storageДЄlways keep your DEF free from contamination and stored properly. вЂњIf stored under correct conditions, DEF should last up to two years,' says Miller. Also, sunlight degrades the urea so keeping DEF in a shaded space that is dry and clean will help prevent contamination,вЂќ says Miller. вЂњAbout 95 oF is the maximum temperature the DEF should be stored long term. There is greater concern on the warm side. The on-board systems will heat up and thaw the DEF in these conditions so it can be used when needed. It is common for machines to be parked outside and may be exposed to these colder temps. However, DEF can freeze and thaw without any negative consequences. How should DEF be stored?ДEF will freeze at 12 oF, so storing out of the elements is ideal.

If an operator goes to the extreme and operates the machine without any DEF, a dealer may need to come out and reset some codes, but the system canвЂ™t be damaged by operating the machine without DEF,вЂќ says Miller. Once itвЂ™s refilled, all the fault codes are reset, and life goes back to normal. And then, if warnings continue to be ignored, the machine will de-rate the engine to basically force the operator to get out of the machine and refill the system. If the operator ignores the warnings, the machine will start logging diagnostic codes. In the simplest form, there is a level sensor in the tank that monitors the DEF level, and if the level gets too low, the machine will advise the operator that that tank is getting low and needs filling up. вЂњWithin Cat, and among industry peers, the systems are robust against operating a machine without DEF. What happens when you operate a machine without DEF? As the newly combined molecules flow through the catalyst filter in the aftertreatment system, it breaks down those components into nitrogen and water, which are harmless gasses so itвЂ™s taking harmful gases and converting it into a harmless gas,вЂќ says Miller. вЂњIn diesel exhaust emissions systems, when we spray DEF into the diesel exhaust gases, a chemical reaction takes place. You could use regular water, but deionized water prevents scaling in the system, among other things,вЂќ says Miller. вЂњDEF is a simple product made of 67.5 percent deionized water and 32.5 percent urea. Here are the topВ questions about DEF and theВ most common ways DEF gets contaminated. вЂњDEF and the onboard systems that use it have been engineered, and most engine manufacturers have made considerable investments in it, so it will probably be around for the foreseeable future.вЂќ So, a lot of the latest equipment use DEF and other system components as a cost-effective means of eliminating NOx from diesel engines,вЂќ says Andy Miller, service training manager, Caterpillar. One of the key emissions that these standards are designed to reduce is nitrogen oxides (NOx). вЂњMany areas in the world have introduced standards to reduce emissions that are produced by diesel engines.

Environmental Protection Agency (EPA) standards for diesel engine, yet there are a lot of people who donвЂ™t understand what DEF is, its function and how to store it.

Fluids are essential for machine operation, and contractors shouldВ familiarize themselves with how to handle them and use them to ensure their equipment functions properly.Дiesel exhaust fluid (DEF) has been on the market since 2014 as one component to creating an engine aftertreatment system that meets U.S.
