Yuchai and Weichai compete for stricter emissions standards market

As the heavy-duty truck market slumped in the first half, engine manufacturers were also hit heavily. Thus, many of them started to compete fiercely in specific market segments as a tactic. Beijing started to implement the Beijing-V emissions standards for heavy-duty trucks from June 1 with the stricter Super Beijing-V standards to be enforced on January 1, 2016. Major engine manufacturers such as Yuchai Group and Weichai Power have ignited a battle in the medium- and heavy-duty truck engine market of Beijing, which is bound to expand into other regions.

Weichai’s Super Beijing-V vs. Yuchai’s Euro-VI

Weichai Power launched its Super Beijing-V engines responding to the new Beijing-V emissions standards in June and supplied brands such as Foton Auman and Shaanxi Auto. The 80,000th Auman green slag truck rolled off the production line at Foton’s production base in Huairou, Beijing on June 27 equipped with Weichai’s Beijing-V emissions standards-compliant engine.

According to an insider of Guangxi Yuchai Machinery Co., Ltd., the company has completed the R&D of Super Beijing-V product and will put it into production after receiving environmental protection certificate. “The Super Beijing-V engine will hit the market within the year,” disclosed a person familiar with the matter. “Different from competitors, Yuchai launched Euro-VI products first and would extend to Super Beijing-V engines at a later stage.”

Although Yuchai has not officially launched its Super Beijing-V product, its Euro-VI engine is ready for mass production. The first Euro-VI diesel engine of Yuchai was equipped on a Foton AUV bus. Yuchai is also the sole domestic provider of Euro-VI diesel engines to Beijing Bafangda Passenger Transport Co. besides some overseas brands, said the company. According to the above executive, the Euro-VI products of Yuchai have been launched in Beijing and can fully fulfill the demand of Super Beijing-V engines. Though without cost advantages, the Euro-VI products are technically ready.

Super Beijing-V engine has a completely different technical route from State-V and Beijing-V emissions standards compliant-engines, which is more like a Euro-VI engine. Weichai Beijing-V engine adopts the CR WGT SCR ASC technical route, similar to that of the State-V engines with emissions reduction of around 40 percent compared with State-IV emissions standards. Weichai Super Beijing-V engine, on the other hand, adopts the TV CR DOC DPF SCR ASC technical route, similar to the Euro-VI engines. Particle emission limit of Weichai Super Beijing-V engine is 10 percent of that of Beijing-V standards, which is even lower than Euro-VI standards. But Euro-VI standards are stricter in NOx emission than Super Beijing-V standards.

Different target market

The two engine tycoons, Weichai and Yuchai, have completely different target markets. For example, the Yuchai Super Beijing-V engine mainly equip the 6.5L 6J series and 8.4L 6L series.

The Beijing market only demands for about 2,000 to 3,000 diesel bus engines each year due to market preference to LNG and CNG buses, electric buses and hybrid buses. Yuchai accounts for one-third of the 3,000-unit orders and takes up around 60 percent market share of public transport buses.

In contrast, Weichai focuses more on heavy-duty truck market such as the Super Beijing-V slag trucks. Weichai launched three Super Beijing-V engines, the WP7, WP10 and WP12, and can equip slag trucks and public transport buses that are required to comply with the Super Beijing-V emissions standards. WP7 engines mainly supply public transport buses, while WP12 engines mainly supply heavy-duty slag trucks.

Weichai joined Foton-Daimler to release its latest Super Beijing-V products this June in the second plant of Foton Auman. Sales of Auman slag trucks accumulated to about 80,000 units with 5,000 sold in Beijing, Tianjin and Heibei Province and 1,500 units sold solely in Beijing. As the largest supplier of Foton-Daimler, Weichai has supplied 650,000 engines to Foton Auman trucks.

Yuchai Group, on the other hand, is not giving up on heavy-duty truck market such as slag trucks, commented an executive. “We are endeavoring in providing products fulfilling the city’s emissions standards and try to increase our market share in this segment,” said the executive.

According to policies announced by the Beijing Environmental Protection Bureau in May, the capital officially implemented the Beijing-V emissions standards for diesel engine heavy-duty trucks with stricter NOx and particle emissions standards. The policy also requested emissions limit of new particulate matters. Newly added diesel engine heavy-duty trucks, including public transport buses, sanitary trucks, tourist buses, post trucks, slag trucks, scheduled buses, school buses, and airport shuttle buses, should install Diesel Particulate Filter (DPF) and comply with the Super Beijing-V emissions standards starting from January 1, 2016. According to researches, Beijing-V and Super Beijing-V emissions standards-compliant vehicles can reduce 40 percent of NOx emissions on average per vehicle than their State-IV emissions standards-compliant counterparts and effectively reduce pollution.
