15L High-Horsepower Gas Engine and Human-Centered Cab Design: A Close Look at the Chenglong H7 High-Horsepower LNG Tractor

In 2024 at the Chenglong 67 Brand Customer Day event, Dongfeng Liuzhou Motor (DFLZM)introduced its new LNG tractor truck. In an era where high horsepower is highly sought after, users also have high expectations for the power of LNG tractor trucks. To achieve cost reduction and efficiency improvement, manufacturers must ensure a perfect match of the powertrain, as demonstrated in the latest Chenglong H7 tractor truck.

Upgraded Luxury Cab: Stylish and Safe

Among domestic heavy-duty trucks, Chenglong’s aesthetic appeal has always been a standout. The Chenglong H7 LNG tractor truck features the latest luxury cab, designed from the ground up domestically. Its dual fuel design allows for better layout, accommodating both fuel and LNG trailers without the need for a new trailer. The truck’s logo is illuminated, and the front grille is finished in a textured matte brown with chrome accents, making it a striking presence on the road.

The headlights have been upgraded to mainstream LED lights, with low beams equipped with lenses to evenly distribute light on the road, enhancing nighttime driving safety. The lights also feature automatic configuration, turning on in low light conditions.

When discussing the Chenglong H7 LNG tractor truck, its safety and comfort cannot be overlooked. The truck uses a skeletal frame cab and integrated anti-collision doors, meeting the stringent EU ECE R29 collision test standards, ensuring maximum protection for occupants. The cab’s high-roof flat-floor design offers significant convenience with its spacious interior, and the four-point air suspension provides a smooth ride over bumpy roads.

Stylish Interior: Comfort of Home

For drivers, the seat and steering wheel are the most frequently used components. The Chenglong H7 LNG tractor truck features multifunctional airbag seats and a multifunctional steering wheel. The seat is covered with high-end leather, offering adjustments for firmness, height, lumbar support, and ventilation and heating functions, reducing driver fatigue on long journeys.

The newly designed four-spoke multifunctional steering wheel is ergonomically optimized, with buttons on both sides for controlling cruise control, multimedia, phone, and various other functions, allowing the driver to operate most features without taking their hands off the wheel, thus preventing distraction.

Chenglong has long promoted the concept of “truck lifestyle,” with numerous amenities for daily living. For instance, there is a factory-installed clothes drying rod behind the sunroof, so drivers can hang clothes to dry without needing to stop or exposing them to dust.

Additionally, the truck can be equipped with parking air conditioning and heating, providing a comfortable environment inside the cab regardless of the season. This thoughtful consideration is ideal for drivers waiting for loads or spending the night in the truck.

15L High Horsepower Gas Engine, Weight as Low as 8.9T

In terms of power, the Chenglong H7 LNG tractor truck is equipped with a 15L high horsepower gas engine, delivering up to 590 horsepower and 2600 Nm of torque, with a B10 lifespan of up to 1.8 million kilometers, balancing power, fuel efficiency, and durability.

The gas tank can be customized to hold up to 1500L, made of aluminum alloy for leak prevention and pressure resistance, ensuring extended range and safety. The transmission is a 12-speed aluminum casing ATM gearbox with a fully synchronized and helical gear design, offering easy gear shifting and improved heat dissipation due to the aluminum casing. The transmission can also be equipped with a hydraulic retarder, providing a maximum braking torque of 4000 Nm, reducing the frequency of brake usage and wear on long downhill slopes for safer descents.

The rear axle is a new lightweight 440 axle with a 3.7 golden ratio. The wheel ends are maintenance-free from ConMet, with oil change intervals up to 500,000 kilometers, reducing maintenance frequency and operating costs, while enhancing vehicle uptime.

Compared to conventional models with integral suspension, the Chenglong H7 LNG tractor truck uses split lightweight suspension, reducing weight by 150 kg. The frame is made from high-strength single-layer steel, increasing strength by 50% and reducing weight by 30%. Combined with lightweight measures for the engine and auxiliary parts, the vehicle’s weight can be reduced to a minimum of 8.9T. In this era of maximizing payload, being 100 kg lighter allows for an additional 100 kg of cargo, making Chenglong’s lightweight design 300 kg lighter than competitors, enabling more load and higher earnings!
