HOW TO CHECK YOUR DIESEL’S EXHAUST FLUID LEVEL (DEF)
Since DEF is injected right into the after-treatment method, the demand for quality management is critical to ensuring optimum operation of the gear in question. Deterioration of DEF quality may have serious consequences in the after-treatment methods and considerably decrease their lifespan.
DEF testing gear is currently in use throughout North America to make sure the very ideal DEF quality. You are able to utilize discoverDEF.com to hunt for DEF quality gear suppliers. DEF quality controllers can take unique shapes like the use of mobile refractometry gear (see picture ), which can be utilized to guarantee DEF quality in any way stages of manufacturing and/or transport.
Refractometry gear measures the braking index of this liquid by mild, supplies DEF quality guarantee, and computes the corresponding DEF immersion. Onboard DEF detector systems, set up in contemporary equipment, track DEF caliber, and immersion from the DEF tank. Advanced lab equipment can also be utilized to assess DEF concentration and quality throughout delivery and production phases.
DEF is created of pure urea along with also de-ionized water can be a non-toxic, colorless, odorless, and also high-temperature liquid. DEF is accountable for moderating your automobile’s emissions and fulfilling EPA guidelines. DEF is obligatory for a procedure called selective catalytic reduction. This procedure operates by deflecting your diesel’s exhaust fumes via a filter and then to some catalyst. The gases combination with the DEF turns dangerous emissions into some benign blend of nitrogen and water.
Much like all other automobile fluids, tracking the DEF rates ought to be a part of your automobile’s continuing maintenance. Here’s a fast guide on all you want to learn about assessing your petrol exhaust fluid amount.
To begin with, you can analyze your DEF by visually assessing clarity, making sure there are no debris or pollutants floating in the liquid. This is only going to check for debris and color from the item which could possibly clog filters onto the SCR system. If the DEF isn’t any color but apparent, you might have an issue with nutrient contamination. This method won’t supply the attention of urea to any vitamin contaminates.
Visual Evaluation Handheld Test Secondly, you may use a handheld DEF Chek Tester or even buy a digital handheld refractometer such as the Misco DEF-201 at a price of about $360. This will assess the immersion specifications of this fluid to guarantee 32.5percent of this fluid will be urea. If not, 1 or 3 disks are drifting then you need to change out your fluid. 0 < 29% Urea Concentration 1 Disc 30 percent Urea Concentration 2 Fragrant 32.5percent Urea Concentration 3 Fragrant 35 percent Urea Concentration Accredited DEF Testing Lab
Third you can send samples of your own DEF to an external laboratory. Most laboratory tests will measure what into this ISO 22241 specification, debris, concentration, and the existence of any contaminates.

Assessing the DEF Degrees.
DEF is kept in a tank onboard the automobile and also chucked into the exhaust system. The storage container is generally located either close to the gas tank on a vehicle, or close to the region of the spare tire on a vehicle. All vehicles using diesel engines assembly 2010 or after EPA guidelines possess a dash warning system that alerts you if the DEF amount is reduced.
Topping Away from the DEF.
Adding more DEF is simple because it can be discovered at all truck stops and electrical parts shops. You could even locate DEF at important OEM places and distributor places. As of 2013, a few trucks stop additional DEF pumps beside the gas pumps so you are able to fill both fluids up without even transferring your automobile. Even should a degree check does not imply that DEF is reduced, it’s a very great practice to fill up until long excursions to steer clear of any difficulties.
Number of DEF Your Own Diesel Programs .
DEF intake can vary according to ecological variables but is generally expected to be between 2 and 3% of gas consumption. This implies that to get a gas truck using a 36-gallon gas tank, approximately 1 gallon of DEF is going to be utilized for each complete tank of gasoline. Two common elements that bring about DEF ingestion percentage would be the car’s intended use and geographic elements such as the kind of terrain.
Shelf Life of Diesel Exhaust Fluid.
The shelf life of DEF is a part of ambient storage space. DEF can endure for approximately two years in the event the storage temperature doesn’t exceed 75 degrees Fahrenheit for a protracted quantity of time. DEF that’s bought at an auto parts supply shop or automobile stop ought to have an expiration date.
