About dxi

Types of Dxi

Dxi refers to various types of diesel exhaust fluid (DEF) injection systems present in vehicles with selective catalytic reduction (SCR) technology. SCR uses an ammonia-based aqueous solution composed of urea, which is 32.5%, and water, which is 67.5%, to reduce nitrogen oxide emissions in the exhaust. The fluid is injected into the exhaust stream, where it mixes and breaks down into ammonia through a hydrolysis reaction. The ammonia then reacts with the nitrogen oxides in the SCR catalyst, transforming them into harmless water vapor and nitrogen that gets released into the atmosphere.

  • Single Dxi: A single DXI system has one DEF injection system for each SCR-equipped engine. This system injects the DEF solution directly into the exhaust stream of the engine. It uses a single nozzle to disperse the DEF solution into the exhaust gas stream. The nozzle atomizes the fluid into tiny droplets, ensuring a thorough reaction with the exhaust gases. The single DXI system is widely used in trucks and buses.
  • Double Dxi: A double DXI system has two separate DEF injection systems that serve one SCR system. Each injection system is equipped with its own supply module, including pumps, heaters, and filters, ensuring a reliable and precise DEF dosing. The two injection systems work in unison to optimize the SCR system's performance, providing even distribution of DEF and enhancing urea utilization efficiency. The double DXI system is ideal for heavy-duty applications.
  • Multi Dxi: Multi DXI systems have multiple DEF dosing systems that serve a single SCR system. These systems are designed for large vehicles with high exhaust flow rates. The multi-DXI system ensures uniform distribution of DEF across the exhaust stream, improving the SCR catalyst's urea utilization efficiency. Each injection system is synchronized to deliver precise urea dosing, optimizing the SCR system's performance and minimizing NOx emissions. Multi DXI systems are used in heavy-duty trucks, buses, and industrial machinery.

    Cost is always an important factor to consider. Find Dxi that fits the budget but also offers the required features and performance. Consider the long-term value and return on investment rather than the initial cost.

How to DIY and replace dxi

Replacing Dyna boxes can be a straightforward DIY task for those with basic mechanical skills. Always refer to the owner's manual of the specific vehicle for detailed instructions. Here's a general guide:

  • Tools Required:

    Socket set, Wrench set, Screwdrivers, Torx bits, Pliers, Torque wrench (for reassembly), Safety gear (gloves, glasses, etc.)

  • New DXI Unit:

    Ensure it is compatible with the specific make and model of the vehicle.

Step-by-Step Guide

  • Safety First: Ensure the vehicle is parked on a level surface, the ignition is off, and the battery is disconnected.
  • Access the Dyna: Depending on the vehicle, the Dyna may be located under the seat, in the engine bay, or in the trunk. Refer to the manual to find its exact location.
  • Remove the Cover: Use the appropriate tools to remove any covers or panels securing the Dyna box.
  • Disconnect Wires: Take pictures or make a diagram of the wiring connections to help with reassembly. Disconnect all wiring harnesses from the Dyna.
  • Remove Mounting Bolts: Use sockets or wrenches to remove the bolts holding the Dyna in place. Carefully lift the Dyna out of its location.
  • Install the New DXI: Place the new DXI in the mounting location. Secure it with mounting bolts and torque them to the manufacturer's specifications.
