Tier4 Issues on export units

As environmental regulations continue to tighten around the world, Tier 4 Final diesel engines have become the norm in many industries, particularly in heavy equipment and machinery. However, in countries where low sulfur diesel is not readily available, these engines can face significant problems that can lead to costly downtime and repairs.

Tier 4 Final engines are designed to run on ultra-low sulfur diesel (ULSD) fuel, which has a maximum sulfur content of 15 parts per million (ppm). However, in many countries, especially developing nations, high sulfur diesel fuel with sulfur content as high as 5,000 ppm is still in use. This poses a major challenge for Tier 4 Final engines as high sulfur content fuel can damage the emissions control systems and cause other issues, including clogging of filters and excessive soot buildup.

One of the main problems caused by high sulfur diesel is the sulfuric acid that is produced during the combustion process. This acid can corrode and damage sensitive components in the engine, including exhaust gas recirculation (EGR) valves, diesel particulate filters (DPF), and selective catalytic reduction (SCR) systems. These components are critical to reducing emissions and achieving compliance with Tier 4 Final regulations, so any damage to them can lead to costly repairs and extended downtime.

Another issue with high sulfur diesel is its high ash content, which can also clog DPFs and cause excessive soot buildup. This buildup can reduce the efficiency of the engine and increase the frequency of DPF regeneration cycles, further impacting productivity and uptime.

Given these challenges, it is crucial for companies that operate Tier 4 Final engines in countries with high sulfur diesel to take proactive measures to prepare their equipment for these conditions. One effective solution is to work with dealers like us, who specialize in preparing machines for export to countries with different fuel standards.

Our team can help customers plan ahead of time how to handle their Tier 4 Final engines to run on high sulfur diesel fuel without compromising emissions compliance or performance. We can also recommend and supply alternative fuel additives and lubricants that can help mitigate the effects of high sulfur diesel and extend the life of critical engine components.

In addition to modifications and recommendations, we also offer training and support services to help customers maintain and troubleshoot their Tier 4 Final engines in challenging operating environments. Our goal is to ensure that customers can continue to operate their equipment reliably and cost-effectively, even in regions with less stringent fuel standards.

In conclusion, Tier 4 Final diesel engines are an essential technology for meeting emissions regulations around the world. However, in countries where low sulfur diesel fuel is not widely available, these engines can face significant challenges that can impact productivity and increase operating costs. By partnering with dealers like us, customers can take proactive steps to prepare their equipment for these conditions and ensure that they can operate their Tier 4 Final engines with confidence and reliability.
