Designed to deliver AdBlue (urea solution) into the exhaust stream with high accuracy, this feed module enables the conversion of harmful nitrogen oxides (NOx) into harmless nitrogen and water vapor. As emissions regulations become increasingly strict, components like the 81.15403-6101 play a central role in ensuring compliance, fuel efficiency, and sustainable engine performance.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_is_an_AdBlue_Feed_Module\"><\/span>What is an AdBlue Feed Module?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>An AdBlue feed module is an integrated assembly that includes a dosing pump and control unit responsible for supplying the correct volume of AdBlue from the tank to the dosing injector. It ensures consistent pressure, temperature monitoring, and flow regulation, enabling precise injection according to the vehicle\u2019s operating conditions.<\/p>\n<p>The 81.15403-6101 feed module is specifically designed for MAN trucks equipped with Euro 5 engines and SCR systems. It forms a closed-loop system that communicates with the engine control unit (ECU) to adjust dosing in real time based on sensor feedback from the exhaust stream.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Technical_Specifications\"><\/span>Technical Specifications<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<ul data-spread=\"false\">\n<li><strong>Part Number:<\/strong> 81.15403-6101<\/li>\n<li><strong>Function:<\/strong> AdBlue delivery pump and module<\/li>\n<li><strong>Operating Voltage:<\/strong> 24V (standard for commercial vehicles)<\/li>\n<li><strong>Operating Pressure:<\/strong> Calibrated for SCR system requirements<\/li>\n<li><strong>Construction:<\/strong> Composite and aluminum materials with integrated electrical connectors<\/li>\n<li><strong>Temperature Range:<\/strong> -40\u00b0C to +85\u00b0C<\/li>\n<li><strong>AdBlue Compatibility:<\/strong> ISO 22241-compliant urea solution<\/li>\n<li><strong>OEM Application:<\/strong> MAN TGS, TGX, and other Euro 5 models<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"Key_Features_and_Benefits\"><\/span>Key Features and Benefits<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"1_Precise_AdBlue_Dosing\"><\/span>1. <strong>Precise AdBlue Dosing<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The core function of the MAN 81.15403-6101 AdBlue Feed Module is to deliver exact quantities of AdBlue under varying load and engine conditions.
