EGR heavy trucks are being sought after by users. Weichai Yuchao immersed in the development of EGR products.

In recent days, Huang Dejun, the manager of an Anhui Lu'an heavy truck dealership, has been receiving feedback from customers who purchased National III heavy trucks. Many users have reported that these vehicles are difficult to operate, with high fuel consumption and low cargo capacity. As a result, they have asked Huang whether his dealership could provide some trucks equipped with EGR engines. EGR-powered heavy trucks are becoming increasingly popular among users. Huang Dejun’s company is a domestic distributor for a major heavy truck brand in Lu'an. Since July 1st this year, the dealership has sold only six National III trucks—three concrete mixers and three regular trucks. According to Huang, these models feature high-pressure common rail fuel injection systems, which not only come with higher initial costs but also increased operational expenses. He explained, “Many users have asked me to sell EGR-equipped trucks because they find them more efficient and cost-effective.” With the full implementation of National III emission standards, domestic manufacturers have already started introducing new models that meet the requirements. Companies like Sinotruk, Dongfeng Commercial Vehicles, and others have launched new products. Notably, Sinotruk has taken a different approach by developing cost-effective EGR technology. Compared to National II trucks, EGR models only cost about 10,000 yuan more, and they are approximately 15,000 yuan cheaper than National III trucks with high-pressure common rail systems. Huang also shared user feedback that EGR trucks are more compatible with local fuel quality. One customer using a high-pressure common rail truck reported spending hundreds of dollars more on fuel over 1,000 kilometers compared to a National II truck with similar power. Additionally, the cargo capacity was not significantly better. The added cost of these trucks means users need to work longer to recoup their investment. This makes the EGR option even more appealing. Industry sources indicated that in July alone, China National Heavy Duty Truck (CNHTC) sold over 5,000 EGR trucks, outperforming other competitors. With growing demand, many companies are now focusing on EGR development. Guo Huanan from the CNHTC Propaganda Department noted that high-pressure common rail engines are about 10,000 yuan more expensive than EGR models. Moreover, China's high sulfur content in fuel can cause nozzle blockages and increase maintenance needs. EGR engines, on the other hand, are easier to maintain and less sensitive to fuel quality. Several engine manufacturers, including Weichai and Yuchai, are working on their own EGR engines. A source from Yuchai mentioned that their EGR heavy-duty engine is currently in testing, and companies are cautious about publicizing developments due to the sensitivity of the technology. Additionally, many truck companies are purchasing EGR engines directly from CNHTC. At a dealer conference in August, Anhui Valin invited representatives from Sinotruk and Weichai to demonstrate their ability to offer both high-pressure common rail and EGR models. This shows that companies are eager to stay competitive and avoid being left behind. From a technical standpoint, domestic EGR technology is maturing. CNHTC has completed R&D, bench testing, and road trials, making mass production feasible. Weichai’s EGR engine is expected to launch within 3–6 months, and other companies may follow suit before the end of the year. CNHTC has also trained its after-sales teams and stocked regional warehouses with EGR-specific parts to ensure quick service. Meanwhile, a representative from North Mercedes-Benz stated that shifting to EGR technology, while costly, benefits market competition and helps break foreign monopolies in key technologies. As EGR trucks become more prevalent, it’s clear that the industry is moving toward a more sustainable and cost-effective future.
