Product Description Product DescriptionWhat is Automotive Grade Urea?Automotive-grade urea, also known as diesel exhaust fluid (DEF), is a solution used in selective catalytic reduction (SCR) systems in diesel engines. It is designed to reduce harmful nitrogen oxide (NOx) emissions from diesel vehicles.Automotive-grade urea is a highly purified solution of urea dissolved in demineralized water. It is non-toxic, non-flammable, and safe to handle. The urea solution is injected into the vehicle's exhaust system, where it undergoes a chemical reaction with the hot exhaust gases.Inside the SCR catalyst, the urea solution breaks down into ammonia (NH3) and carbon dioxide (CO2). The ammonia reacts with the NOx emissions, converting them into nitrogen (N2) and water vapor (H2O), which are harmless components of the air we breathe.What should we pay attention to when we choose an AGU supplier? 1. Quality assurance. Look for suppliers that adhere to ISO 22241 standards. This ensures that the prilled urea you purchase meets the necessary purity and quality requirements. 2. Certification and Compliance: For example, in Europe, DEF must meet the DIN 70070 standard. and do they have the REACH certificate that is required in the Europe market? 3. Supply Chain Capability: They should have the capacity to provide a consistent and uninterrupted supply of Automotive urea to meet your requirements. 4. Pricing and Contracts: Compare prices from different suppliers, but also consider the overall value provided.Detailed PhotosAccording to ISO22241 standardTest ItemsUnitspecificationT-nitrogen%>46moisture%<0.5Biuret%<0.8alkalinity(NH3)%<0.05aldehydemg/kg<15.4insoluble mattermg/kg<61.5PO4mg/kg<1.5Camg/kg<1.5Femg/kg<1.5Cumg/kg<0.6Znmg/kg<0.6Nimg/kg<0.6Crmg/kg<0.6Mgmg/kg<1.5Namg/kg<1.5Kmg/kg<1.5Almg/kg<1.5CertificationsPackaging & ShippingOur Advantages***10 years export experience***Fast delivery time: 2 weeks with quantity below 500tons.***OEM packing available***free sample can be provided***Free SGS reportWhat is the negative effects of using inferior urea to produce Diesel Exhaust Fluid 1. Reduced Effectiveness: Inferior urea may not have the same purity or quality standards as automotive-grade urea. This can result in a lower conversion efficiency of nitrogen oxide (NOx) emissions in the selective catalytic reduction (SCR) system. As a result, the vehicle's emissions may not be effectively reduced, potentially leading to environmental non-compliance or failing emission standards.2. Damaged SCR System: Low-quality urea can contain impurities or contaminants that can cause damage to the SCR system components. These impurities can clog or foul the SCR catalyst, reducing its effectiveness and potentially leading to costly repairs or replacements.3. Increased Maintenance Costs: Inferior urea can lead to more frequent clogging or malfunctioning of the SCR system, requiring more frequent maintenance and cleaning procedures. This can result in increased maintenance costs and downtime for the vehicle.4. Risk of Engine Performance Issues: Poor-quality urea may contain higher levels of impurities that can adversely affect the engine's performance. This can result in decreased fuel efficiency, power loss, or other engine-related issues, reducingoverall vehicle performance.5. Release of Harmful Emissions: If impure urea is used, it can lead to the release of harmful ammonia (NH3) or other byproducts into the exhaust system. These emissions can contribute to air pollution and negate the purpose of using SCR technology to reduce harmful emissions.Our teamOur clientsFurther reading---The market for DEF is being created due to the new emission requirements promulgated by the EPA to meet the most recent Clean Air Act specifications. As depicted below the progressive reduction in diesel emissions has driven tremendous changes in engine requirements over the past 15 years. These efforts have been focused on reducing particulates, S, and NOX emissions. DEF is focused on meeting the 2010 requirement for NOX emissions reductions.The specific approach used to reduce NOX emissions requiring DEF is referred to as SCR or Selective Catalytic Reduction. SCR uses a chemical called Diesel Exhaust Fluid (DEF / Urea) and a SCR catalytic converter to significantly reduce nitrogen oxide (NOx) emissions in diesel engines.Contact us for more details.
