In August, commercial vehicle production and sales continued to grow year on year, but the pace of growth narrowed significantly. In the truck market, all segments declined except for medium-duty trucks, which posted a slight month-on-month increase. Meanwhile, although bus sales rose month on month and the year-on-year decline narrowed, individual sub-segments once again suffered across-the-board losses in August.

　　Overall, as the second half of the year began, the commercial vehicle market has been cooling. After a sharp 63% year-on-year increase in June, the growth rate narrowed over July and August, leaving a still-substantial 42% rise. Accordingly, what changes have occurred in the diesel engine powertrain market—closely tied to commercial vehicles—and in the domestic internal combustion engine market more broadly?

　　Now, please watch the report from First Commercial Vehicle Network.

　　In August, internal combustion engine sales reached 4.17 million units, up 11.9% year on year! The growth rate of diesel engines narrowed to 38.7%.

　　According to data from the China Internal Combustion Engine Industry Association’s Monthly Sales Report, on a comparable basis, domestic internal combustion engine sales totaled 4.1711 million units in August this year, up 1.71% month-on-month and 11.87% year-on-year. Cumulative sales for January–August reached 27.8872 million units, down 6.38% year-on-year, with the year-on-year decline narrowing by 2.62 percentage points compared with the previous month. Since April this year, the internal combustion engine market has posted five consecutive months of year-on-year growth; during the first four months, the rate of increase widened each month, while in August the growth rate narrowed by nearly 2 percentage points.

Weichai exceeds 650,000 units; Yunnei and Yuchai vie for second place; Foton and Dongfeng show strong growth momentum—diesel engine data for the first eight months.

　　Among the two major categories—gasoline and diesel engines—diesel engine sales in August totaled 506,200 units, down 6.22% month-on-month but up 38.71% year-on-year (notably, the year-on-year growth rate for diesel engines also narrowed in August). From January to August this year, cumulative diesel engine sales reached 3.9985 million units, accounting for 14.33% of total internal combustion engine sales. Meanwhile, gasoline engine sales in August were 3.6636 million units, up 8.92% year-on-year; cumulative sales from January to August totaled 23.8660 million units, with the monthly year-on-year growth rate having already begun to narrow in July, earlier than that of diesel engines.

　　Commercial‑vehicle internal combustion engines, which have drawn significant industry attention, recorded sales of 320,900 units in August, down 7.64% month over month; year‑over‑year growth narrowed from 85% in July to 53.17%. Year‑to‑date sales through August totaled 2.4523 million units, up 23.06% year over year. Notably, across all application segments, commercial‑vehicle ICVs posted the highest year‑over‑year growth—both monthly and cumulative—making them the primary driver of sustained positive growth in the internal combustion engine market.

　　From January to August, sales of multi-cylinder diesel engines reached 3.384 million units; Weichai exceeded 650,000 units, and Yunnei posted a year-on-year surge of 52%.

　　Diesel internal combustion engines are classified as either single-cylinder or multi-cylinder. Single-cylinder diesel engines are primarily used in agricultural machinery; August sales once again posted year-on-year growth, and the cumulative decline from January to August narrowed to 5.84%.

　　Multi-cylinder diesel engines are primarily used in the commercial vehicle market. With the commercial vehicle market posting rapid growth for five consecutive months, multi-cylinder diesel engines have also recorded substantial month-on-month increases over the same period. In August, companies producing multi-cylinder diesel engines sold a total of 427,400 units, down 7.50% from the previous month but up 42.79% year on year (the year-on-year growth rate narrowed significantly in August, falling 26.51 percentage points from July). Cumulative sales from January to August reached 3.3838 million units, a year-on-year increase of 18.24%.

　　From January to August this year, the top ten companies in cumulative multi-cylinder diesel engine sales were, in order: Weichai, Yunnei Power, Yuchai, Jiefang Power, Anhui Quanchai, Foton Cummins, Jiangling Holdings, Zhejiang Xinchai, Dongfeng Cummins, and Shanghai Diesel. Starting in April, FAW Jiefang Xichai and Dachai began reporting consolidated figures under Jiefang Power and have consistently held fourth place on the list. Based on market share calculations, Weichai Group’s multi-cylinder diesel engine sales for January–August totaled approximately 657,500 units.

　　The top ten companies in the multi-cylinder diesel engine market recorded combined sales of approximately 2.67 million units, accounting for 78.95% of total sales. Compared with January–July this year, the market structure remains stable; the only change in the rankings is that Foton Cummins moved up to sixth place, overtaking Jiangling Holdings. However, the composition of the top ten firms and their aggregate market share have not shifted significantly. Among them, Weichai, Yunnei, Foton Cummins, Shangchai, and Dongfeng Commercial Vehicle all posted cumulative sales growth exceeding 30%, with Yunnei’s increase around 51.6%.

　　The most intriguing contest is the battle for second place between Yunnei Power and Yuchai Group, both of which hold market shares between 10% and 11%, with a gap of just 0.31 percentage points—so who will emerge as the ultimate winner?

　　Multi-cylinder diesel engines for commercial vehicles: Yunnei’s market share approaches 12%, while Fukan and Shangchai climb in the rankings.

　　In August this year, sales of multi-cylinder diesel engines for commercial vehicles reached 262,100 units, down 9.43% month-on-month but up 47.64% year-on-year. From January to August, cumulative sales totaled 2.0705 million units, a year-on-year increase of 19.24%.

　　From January to August this year, the top ten companies in cumulative sales were, in order: Weichai, Yunnei Power, Jiefang Power, Yuchai, Foton Cummins, Jiangling Holdings, Dongfeng Cummins, Quanchai, Shangchai, and Dongfeng Commercial Vehicle. Compared with the period from January to July, the top four rankings remained unchanged; Foton Cummins moved up to fifth place from sixth by overtaking Jiangling Holdings, and Shangchai advanced to ninth from tenth by passing Dongfeng Commercial Vehicle. Foton Cummins engines primarily supply Foton’s Ouman heavy trucks, while Shangchai engines mainly equip SAIC Hongyan heavy trucks. The rise in their diesel engine sales rankings is closely linked to the sharp increase in sales of Ouman and Hongyan in the heavy-truck market. According to production and sales data released by the China Association of Automobile Manufacturers, Foton and Hongyan led the industry in cumulative sales growth in the tractor segment, with Foton posting a year-on-year increase of 99% and Hongyan a 151% rise.

　　The top ten companies accounted for 88.57% of total sales. Weichai leads the multi-cylinder diesel engine market for commercial vehicles with a 23.08% share, followed by Yunnei Power at 11.93%, Jiefang Power at 10.50%, Yuchai at 9.87%, Foton Cummins at 9.37%, Jiangling Holdings at 9.35%, Dongfeng Cummins at 4.52%, Quanchai at 4.46%, Shanghai Diesel at 2.79%, and Dongfeng Commercial Vehicle at 2.69%. Compared with January–July, the companies that increased their market share include Yunnei Power, Foton Cummins, Jiangling Holdings, Dongfeng Cummins, Shanghai Diesel, and Dongfeng Commercial Vehicle, with net increases of 0.28%, 0.12%, 0.16%, 0.01%, 0.2%, and 0.21%, respectively; among them, Yunnei Power recorded the fastest growth in market share.

　　The brightest star—Yunnei Power—is poised to make even greater strides in the future.

　　Looking at the commercial multi-cylinder diesel engine market from January to August this year, Yunnei Power may not be the brightest star, but it is certainly one of the most prominent—its sales have posted substantial year-on-year growth, and its market share has continued to rise steadily.

　　The editor notes that during the same period last year (January–August), Yunnei Power’s market share in the multi-cylinder diesel engine segment for commercial vehicles was just under 10%. However, since the beginning of this year, its share has steadily increased: 9.43% in January, 9.74% in February, 11.55% in March (moving it up to second place), 11.76% in April, 11.51% in May, 11.65% in June, and 11.65% in July. By August, it had risen to 11.93%, a gain of 2.5 percentage points compared with January, firmly maintaining its position as the industry’s second-largest player. From below 10% to surpassing 11% and now approaching 12%, Yunnei Power’s rapid market growth not only underscores its strong resilience in navigating the challenges of the pandemic but also reflects customers’ recognition of its products and quality.

　　It is reported that Yunnei Power, guided by market demand, has achieved breakthroughs in gasoline engines and hybrid powertrains while simultaneously commercializing its Dewei series of China VI-compliant 2.0L–6.7L engines. The company now offers a diversified product portfolio with outstanding performance metrics, comprehensively meeting the needs of users across various sectors. Furthermore, in response to evolving national emission standards, Yunnei Power’s China VI diesel, gasoline, and natural gas engines, along with its hybrid powertrains and fuel cell systems, have been developed under the umbrella of its National Enterprise Technology Center, establishing a new structure of “one headquarters and five centers, supported by five major production bases.” This framework provides robust technical support and ensures strong production capacity. Looking ahead, Yunnei Power has additional significant initiatives currently in the planning stages.

　　Conclusion

　　After a period of sustained gains, how will the diesel engine market perform following a brief slowdown in August, as the peak “Golden September” season has already begun and the traditionally strong “Silver October” approaches? Will it once again post rapid growth, driven by the peak season for commercial vehicles?
