On April 10, 2026, the Weichai NG4.0 Pro gas powered new product launch event was held simultaneously in six cities including Zhengzhou, Changchun, Xi'an, Yinchuan, Chengdu, and Jinan. At this multi city linkage event spanning from east to west and north to south, Weichai has launched four new gas powered products, NG4.0 Pro 13L/14L/15L/16L, with a significant impact. As an advanced masterpiece of the NG4.0 platform, the new product relies on industry-leading core technology to achieve a comprehensive leap in power, reliability, and comfort. With the core advantages of "super strength, super economy, and super efficiency", it once again breaks the benchmark of the gas power industry.

Inheriting the same lineage, firing four arrows at once to establish a benchmark in the industry again

On the gas power track, Weichai has never played the role of a pursuer, but has always defined rules through innovation and consolidated its lead through iteration.

In the 1990s, Weichai was the first to invest in the research and development of gas engines, opening up an innovative path in the field of gas power. In 2005, Weichai's first natural gas engine WP10NG was launched, filling the market gap of high-power natural gas engines in China at that time. Subsequently, we will continue to increase our R&D investment and achieve iterative breakthroughs from National V to National VI. From NG1.0 National V lean combustion technology+DOC post-treatment, to NG2.0 National VI equivalent combustion+TWC post-treatment, to NG3.0 National VI power increase of 12%, gas consumption reduction of 5%, and exhaust temperature reduction of 30 ℃, and then to NG4.0 Damali new platform, with performance indicators comparable to diesel engines and exhaust temperature reduction of 30 ℃~50 ℃ - Weichai has built an insurmountable technical barrier in the field of gas power through the iteration of four generations of products in nearly thirty years.

The NG4.0 Pro released this time is comprehensively optimized and upgraded based on NG4.0. With its leading gas consumption advantage, it accurately covers segmented scenarios such as composite transportation, mainline logistics, mountainous and high-altitude transportation, and provides customized professional clean power solutions for users with different needs.

The WP13NG-4.0 Pro has a displacement of 13.3L, a power coverage of 520-570Ps, and a maximum torque of 2600N · m. It adopts a lightweight design for the whole machine, which greatly improves the competitiveness of power and gas consumption. Combined with a vehicle specific calibration strategy, it has become a new benchmark for gas power in the composite transportation market.

The WP14NG-4.0 Pro has a displacement of 14L, a power coverage of 566-610Ps, and a maximum torque of 2800N · m. With excellent gas consumption competitiveness, it is specially designed for mainline standard load and resource-based composite transportation, and is a new tool for users to get rich.

The WP15NG-4.0 Pro has a displacement of 14.6L, a power coverage of 560-630Ps, and a maximum torque of 2800N · m. With strong power and stability performance, it has become the core transport capacity choice for mainline logistics transportation.

The WP16NG-4.0 Pro has a displacement of 15.7L, a power coverage of 640-750Ps, and a maximum torque of 3400N · m. It is responsive, economical, reliable, and durable, designed specifically for road conditions in the southwestern and northwestern highlands and mountainous areas. It is not afraid of high altitudes and long climbs, leading the trend of high horsepower gas power technology.

Technological leap, dual leap in power performance and reliability

Weichai NG4.0 Pro relies on top global resources to achieve breakthrough innovations in core areas such as turbocharging and combustion control, achieving a dual leap in power performance and reliability while balancing comfort and autonomy.

In terms of power and throttle, the NG4.0 Pro is equipped with dual overhead camshafts and a special combustion chamber, integrating three major technologies: low loss and high flow intake, low disturbance pulse boosting, and fast combustion, which improves power responsiveness by 20%; By combining three core technologies of high expansion ratio combustion, efficient EGR acquisition, and ultra-high energy ignition, we have achieved a reduction of 1-2kg in gas consumption per hundred kilometers and maintained a leading position in the industry in terms of throttle effect.

In terms of reliability, NG4.0 Pro has advanced technology optimization for key components. Through cylinder head stress coordination design, efficient cooling, low knock control and other technologies, the B10 has a lifespan of 2 million kilometers, ensuring worry free operation of the entire vehicle under complex working conditions. At the same time, the universalization rate of the entire machine components has reached 90%, and the adaptability of key maintenance parts is strong, resulting in a significant reduction in maintenance costs in the later stage; The lifespan of high-value components has been increased by 40%, further reducing users' long-term maintenance expenses and achieving worry free operation.

In terms of comfort, by restructuring the three major technologies of intake noise reduction, combustion noise control, and exhaust noise suppression, the overall quietness of the vehicle has been improved by more than 40%, further optimizing the driving experience on the basis of strong performance.

It is worth noting that NG4.0 Pro is equipped with a dedicated intelligent brain, with millisecond level precise control, adapted to different gas sources and working conditions, achieving one vehicle, one strategy, intelligent adaptation, more flexible control, and more efficient operation.
