AMTAST Hand Held DEF AdBlue Refractometer Tester for Urea Concentration in Diesel Exhaust Fluid Aqueous Urea Solution with ATC

Product Information

Why does Adblue need to be a pure 32.5% urea solution and why is it important to test it to ISO22241-2? Note: always wash the gauge and pipe assembly after use in clear water to prevent Urea crystal build up. Adblue is one of two commonly used methods to reduce NOx emissions as part of a SCR. The other being Exhaust Gas Re-circulation (EGR) systems that recirculate the exhaust gases with lower oxygen content to reduce peak cylinder temperatures and hence NOx production, but this requires strict maintenance of diesel particulate filters as less oxygen means more un-burnt fuel. In some engines both technologies are used to achieve the ever tightening emission standards. How does Adblue work to remove NOx?

The environmental compatibility of diesel engines as compared to gasoline engines is a matter of great dispute in the discussion about the cause of and measures against anthropogenic climate change. While the combustion of gasoline produces more greenhouse gas CO 2, diesel engines generally exhaust more nitrogen oxides. The nitrogen oxide molecules NO and NO 2, which are included in the generic term NO X, are relevant for air pollution as they cause smog and acid rain in high concentrations and contribute to the depletion of the ozone layer. Hence, there are ambitions to reduce the NO X exhaust in diesel engines on different levels. How can Bellingham + Stanley help you measure DEF easily and effectively?

I have confirmed by listening to the eolys box that the noise comes from there. Sometimes it comes from the boot and that is clearly the AdBlue pump I can hear, but I am certain it is not the AdBlue pump I'm hearing. Your Volkswagen car is fitted with an advanced emissions control system, which helps your vehicle meet the latest Euro 6 exhaust gas regulations. Selective Catalytic Reduction (SCR) using AdBlue®

The size of the AdBlue® tank fitted to your car will vary depending on which Volkswagen model you have, therefore the interval between top-ups will vary. In addition, many factors such as mileage, journey type, driving style and environmental conditions can influence how much AdBlue® is consumed. A passenger car can consume approximately 1.5 litres of AdBlue® every 620 miles (1.0–1.5 litres for the Passat and Passat Estate). The chart below details the AdBlue® tank size and location for all Volkswagen models that use SCR. How will I know if the system needs topping-up? Escalating urea prices have driven the cost of operating an SCR higher than ever before. Regretfully this has led to a new wave of problems where supplies of diluted AdBlue have found their way into the market. Gebruik conform de instructies van de OEM van het voertuig en conform de instructies voor het testen van het SCR-systeem. Adblue works by decomposing to Ammonia and Carbon dioxide at high temperatures of the exhaust. The Ammonia (NH3) in the presence of oxygen (O2) in the air plus the catalyst forms Nitrogen (N2) and water (H2O).

So although Diagbox can estimate the additive remaining it can't be 100%. When it gets to a certain estimated level, it looks at your remaining miles due to the next service interval and if it thinks you won't have enough Eolys fluid to make it until the next service, it will flag up the low additive warning. Eenvoudig te gebruiken en af te lezen. Maak de binnenkant van het apparaat na het gebruik altijd schoon met gedestilleerd water The additive has been full or partially topped up, but the resetting of the additive counter failed or was not completed correctly. The engine ECU therefore thinks the original amount of fluid is in there and not the new quantity. In this scenario it is not so concerning, as at least there is fluid in the tank - so the pump won't run dry. The worst that can happen is the low additive level warning may come on earlier than expected. Moderne dieselemissiesystemen zijn voorzien van technologie die ontwikkeld is om de uitlaatemissies te zuiveren terwijl de uitlaatgassen door de uitlaat gaan. Een van de populairste systemen maakt gebruik van een ureum-oplossing, zoals AdBlue®, die in de uitlaat wordt gespoten voor de katalysator om de stikstofoxiden die uit de motor komen om te zetten in stikstof en water. Wanneer deze systemen niet werken, gaat de motor aanvankelijk over op “thuisbrengmodus” en als het probleem niet wordt verholpen, kan het OBD-systeem van het voertuig voorkomen dat het voertuig wordt gestart. Als onderdeel van de diagnostische routine van deze SCR (AdBlue®-injectie) systemen wordt de druk in het systeem zowel elektronisch via de OBD-software en protocollen als dynamisch gemeten met behulp van manometers. De Laser 8060 bestaat uit een manometer en aansluitslangen waarmee de gebruiker de systeemdruk direct bij de verstuiver (doseermodule) of pomp kan meten. Modern diesel emission systems incorporate technology that is designed to clean up the exhaust emissions as the exhaust gasses pass through the exhaust. One of the most popular systems uses a Urea solution, like AdBlue®, that is injected into the exhaust before the Catalytic convertor to convert the Nitrogen Oxides (NOx) coming out of the engine into Nitrogen and water. When these systems fail the engine will initially fall into “limp mode” and if not corrected, eventually the vehicle OBD system may prevent the vehicle starting. Part of the diagnostic routine for these SCR (AdBlue® injection) systems is to measure the pressure in the system both electronically (via the OBD diagnostic software) and dynamically using pressure test gauges. The Laser 8060 provides the gauge and connection pipes required to allow the user to directly measure the system pressure at the injector (dosing module) or pump.
