AdBlue Impact on Vehicle Reliability

AdBlue, a critical fluid in reducing emissions from diesel engines, is increasingly linked to vehicle reliability issues, particularly in mobile cranes and trucks. This solution, composed of urea and deionised water, is injected into the exhaust of diesel engines to break down harmful nitrogen oxide (NOx) emissions into nitrogen and water vapour, playing a key role in meeting environmental standards. However, concerns are growing over its impact on vehicle performance, especially in heavy vehicles.

_{AdBlue-Related Breakdowns in Cranes and Trucks}

Recently, a significant number of breakdowns in mobile cranes and trucks across Europe have been traced back to AdBlue systems. With around a third of these incidents attributed to AdBlue, there is increasing concern that the system designed to reduce emissions might be compromising vehicle reliability. These breakdowns not only disrupt operations but also pose safety risks and incur significant costs.

Mobile cranes, essential for construction projects, are particularly vulnerable to AdBlue system malfunctions. Issues such as cold engine detection or sensor faults can lead to reduced power or even complete shutdowns. Such failures, especially during critical operations, can be dangerous and cause severe project delays.

Trucks and self-propelled modular trailers (SPMTs) also face challenges from AdBlue-related malfunctions. These vehicles, crucial for transporting heavy loads, can be left stranded by AdBlue failures, causing delays and logistical issues. The consequences extend beyond immediate inconveniences, potentially disrupting entire supply chains and damaging reputations.

_{Safety Risks}

The safety risks associated with AdBlue failures are significant. Unexpected power losses or shutdowns can endanger both operators and other road users. For mobile cranes, a mid-operation shutdown could result in structural failures, while trucks breaking down on busy roads could lead to accidents.

The European Special Transport Association (ESTA) is addressing these concerns by gathering data on AdBlue-related breakdowns. Through surveys and data collection, ESTA aims to identify the root causes of these issues and develop solutions to improve reliability without compromising environmental benefits.

Addressing the challenges posed by AdBlue systems requires industry-wide collaboration. Comprehensive data collection and cooperation between manufacturers, operators, and regulators are essential to develop robust solutions that ensure the reliability of AdBlue systems while maintaining vehicle performance and safety. The future will involve balancing environmental goals with operational reliability, and the insights gathered by ESTA will be crucial in shaping a safer, more reliable transport sector.
