The urea reacts with NOx in the catalytic converter, converting it into harmless nitrogen and water. The efficiency of SCR systems has been significantly improved in the new TDI engines. For example, Audi claims that the latest SCR systems can achieve NOx conversion rates of up to 90% under real-world driving conditions, as tested in accordance with the WLTP (Worldwide Harmonized Light Vehicles Test Procedure) cycle.

• Diesel Particulate Filter (DPF): The DPF is highly effective at trapping particulate matter, also known as soot. The new TDI engines feature advanced DPF designs with improved filtration capabilities. These filters are capable of removing over 99% of particulate matter from the exhaust. Audi also uses advanced regeneration strategies to maintain the DPF’s efficiency over its lifespan.
• Advanced Engine Management: Sophisticated engine control units (ECUs) precisely manage the combustion process, minimizing the formation of pollutants in the first place. This includes optimizing fuel injection timing, combustion chamber design, and exhaust gas recirculation (EGR). The new TDI engines feature highly precise fuel injection systems, capable of multiple injection events per combustion cycle, to further reduce emissions.
• Exhaust Gas Recirculation (EGR): EGR recirculates a portion of the exhaust gas back into the intake manifold. This reduces peak combustion temperatures, which in turn lowers the formation of NOx. Audi’s EGR systems are highly efficient and precisely controlled.

Torque Curve Comparison: TDI Engine vs. Electric Motor

The following is a description of a visual representation comparing the torque curves of a new TDI engine and an electric motor:The visual representation is a graph with two distinct lines representing torque output versus engine/motor speed (RPM). The x-axis represents engine/motor speed, ranging from 0 RPM to a higher value representing the maximum operating speed. The y-axis represents torque, with units of Newton-meters (Nm) or pound-feet (lb-ft).The electric motor’s torque curve starts with a steep, almost vertical climb from 0 RPM, reaching its peak torque very quickly and maintaining it over a wide range of low to mid-range speeds.

This indicates instant torque delivery. The torque then begins to decrease as the motor speed increases, reflecting the motor’s operating characteristics.The TDI engine’s torque curve shows a more gradual increase from 0 RPM. The torque builds up, reaching a peak at a mid-range RPM. This peak torque value is typically less than the peak torque of the electric motor at the low end.

The TDI engine’s torque then gradually decreases as the engine speed increases. The mild-hybrid system enhances the initial torque delivery of the TDI engine, making the curve somewhat more similar to the electric motor’s.The graph clearly demonstrates the key difference: the electric motor’s instant torque delivery compared to the more gradual torque build-up of the diesel engine, even with mild-hybrid assistance.

However, the mild-hybrid technology provides an experience closer to that of an electric vehicle.
