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.

400,000 units are not only a digital breakthrough, but also a manifestation of Weichai's hard power in science and technology. 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, the 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 CO₂ 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.

Strong power is also the main advantage of Weichai engine. The Weichai National VI engine has more torque reserves, lower shift frequency, stronger climbing ability, and 30% increase in starting and overtaking acceleration.

In addition to power and economy, reliability is also the focus of customers' attention. Weichai has launched more than 100 reliability improvement technologies, 500 complete machines have accumulated 450,000 hours of bench endurance tests, 3,500 complete vehicles have 150 million hours of road endurance tests, and 320,000 vehicles in use have accumulated 50 billion kilometers of mileage... The endurance test in the whole time domain has created Weichai Power's safe and reliable "Great Wall". At the same time, the longest life span of Weichai's National VI product emission system can reach 7 years or 1 million kilometers, and the life span of B10 is increased by 30%.

Weichai engines have experienced the flames of 50°C in Turpan, Xinjiang, withstood the low temperature of -45°C in Hailar, Inner Mongolia, and climbed the 5231-meter Kunlun Pass. The rigorous refinement of the "three highs" test makes Weichai National VI engines more adaptable.

In the National VI era, customers pay more attention to comfort. Weichai’s unique full-suspension vibration isolation technology, multiple injection noise reduction technology, intake air stabilization noise reduction technology, low-noise gear system, speed fluctuation control technology and other new generation noise reduction technologies, minimize the noise of the whole machine to 72dBA, Let customers experience the driving experience of a passenger car. At the same time, the on-board intelligent control and cloud service system are interconnected to realize energy-saving driving and efficient operation simultaneously, making the entire vehicle operation smarter and more worry-free.

Thanks to a series of "hard technology", Weichai beat the others, the market broke out in an all-round way, and sales quickly exceeded 400,000 units. The tractor driver Wang Heng is a loyal fan of Weichai. He started to use Weichai engines for transportation more than ten years ago. Six months ago, he bought another Shaanxi heavy truck equipped with Weichai National VI engines. "Dynamics, economy, and reliability are not bad at all. It is practical and suitable for short-distance transportation, especially in environments with poor working conditions such as frequent entry and exit of construction sites."

Beijing Doudian Yaohui Automobile Sales Co., Ltd. even purchased several tractors with Weichai National VI engines in one go. Guan Zhen, the person in charge of the company, said: “As a new thing, National VI products are still in their infancy, but Weichai’s products have performed well. During the more than two years of market promotion, they have completely withstood the test and have been deeply involved in logistics and transportation industries. Customers are welcome."Editor/Baohongying
