National VI is the hottest word in the industry in recent years. On August 17, Weichai, the industry leader, once again set off the National Sixth National Sixth—heavy announced that the production and sales of National Sixth engines exceeded 400,000 units.
According to industry statistics, 400,000 units means that Weichai firmly holds the top spot in the National Sixth Engine market in terms of sales. Get ahead at the start. As early as 2018, Weichai took the lead in the industry to pass the National VI B official certification for heavy-duty diesel engines; in 2021, it obtained the first non-road four-stage environmental protection information disclosure form in China. At the same time, Weichai released the world's first commercial diesel engine with a thermal efficiency of over 50%, setting a new benchmark in the world's internal combustion engine industry.
Over the past ten years, Weichai has invested more than 30 billion yuan in research and development to fully develop a full range of engines that meet emission standards in all fields, such as WP2.3N, WP2.5N, WP3H, WP3N, RA428, and WP4.1N/4.6N. Light-duty power, new medium and heavy-duty power represented by WP6H/7H, WP8H, WP9/10/10.5H, WP11H, WP12/13G, WP13H, WP15H, can efficiently meet the diverse power needs of customers and lead the industry's emission upgrade.
After ten years of sharpening a sword, the scabbard must be sharp. Weichai's full series of National VI products are positioned at high-end, achieving a comprehensive upgrade of "more fuel-efficient, stronger power, safer, more reliable, more adaptable, more comfortable, and smarter", which is extremely competitive in the market. At the same time, compared with China V, Weichai National VI engines have reduced NOx by 80%, PM by 90%, and CO? by 15%.
Decoding "hard technology", the first to promote fuel-saving. Weichai National VI engine rebuilds a new benchmark in fuel economy with five systems including its high-efficiency combustion system, low-friction, low-power system, high-efficiency intake and exhaust systems, high-efficiency pulse supercharging system, and low back pressure aftertreatment system. Compared with the National V, it can save 8% of fuel and save 25,000 yuan in fuel costs a year. For customers, fuel saving is the last word.
