Since their launch, Yuchai’s K14N and K15N high-horsepower gas engines have quickly gained the trust of major heavy truck brands and users across China. Known for their reliability, fuel efficiency, and powerful performance, these engines have become some of the most sought-after models in the industry. With the recent mass production of Dongfeng Commercial Vehicle’s Tianlong KL/KX tractors equipped with Yuchai’s K14N and K15N engines, Yuchai’s “circle of friends” has expanded even further, solidifying its position as a leading engine model.

Following the rollout of the new Tianlong KL/KX tractors, Dongfeng Commercial Vehicle held a “Fuel-Saving Challenge” themed “One Tank, Incredible Range.” The challenge covered a 1,445.2 km route from Jiayuguan to Xianyang, passing through varied terrains including gobi, desert, highways, and national roads. Remarkably, the Dongfeng Tianlong KL540 completed the entire journey on a single tank of gas, with an average consumption of just 24.9 kg/100 km.
How did the Dongfeng Tianlong KL, equipped with Yuchai’s high-horsepower gas engine, achieve such a perfect balance between efficiency and fuel economy? The answer will be revealed at the upcoming launch event for the KX/KL Yuchai gas-powered models on August 10.

Xianyang, located in the heart of the Qin River region, has historically been a crucial commercial hub. Today, its strategic position in the northwest’s transportation network, coupled with abundant and accessible natural gas resources, has made it a prime market for gas-powered vehicles. Dongfeng Commercial Vehicle’s decision to hold the KX/KL Yuchai gas engine launch event in Xianyang reflects their confidence in market demand and their commitment to capturing the northwest gas-powered vehicle market.
The event is themed “Dongfeng and Yuchai: Prosperity on the Horizon.” Since the late 20th century, Dongfeng Commercial Vehicle and Yuchai Machinery have collaborated to produce a series of highly regarded transport vehicles. In the face of fierce competition in the gas-powered vehicle market, Dongfeng Commercial Vehicle has chosen to deepen its partnership with Yuchai, combining their strengths to launch the new Dongfeng Tianlong KX/KL gas-powered models. This collaboration marks a significant breakthrough in the high-horsepower gas truck market.

Recognizing the unique demands of the northwest region, including long transport routes, harsh climate conditions, and stringent timing requirements, Dongfeng Commercial Vehicle and Yuchai have meticulously optimized the design of the Tianlong KX/KL high-horsepower gas models to meet diverse transportation needs.

The new Dongfeng Tianlong KX, equipped with the Yuchai YCK15N engine, focuses on long-haul transport with 570 horsepower, while the Tianlong KL, powered by the Yuchai YCK14N engine, delivers 540 horsepower, ideal for mixed freight scenarios. The launch event will highlight the exceptional performance of these models in terms of power, economy, reliability, and comfort.
In addition, Dongfeng Commercial Vehicle and Yuchai Machinery will announce comprehensive service commitments for key clients of the new Tianlong KX/KL Yuchai gas models. Together, they will offer customers a more cost-effective, powerful gas truck option, providing efficient, economical, and reliable transportation solutions that deliver on their brand promise and continue to create higher operational value for their clients.
