The CNG-powered HOWO 6x4 Tractor Truck, identified as model ZZ4257N3847E1CB, is a heavy-duty vehicle designed for sustainable and efficient freight transport. It is built on a sturdy double-layer frame that provides enhanced durability and load-bearing stability. Powering the truck is a Weichai MT13.43-50 engine, which delivers 430 horsepower and meets Euro V emission standards, making it a cleaner alternative to traditional diesel engines with significantly lower emissions of pollutants such as nitrogen oxides and particulates.

A defining feature of this tractor is its compressed natural gas (CNG) fuel system, which includes 16 individual cylinders with a combined capacity of 2,080 liters. The cylinders are mounted securely and fitted with protective covers to ensure safety during operation. The vehicle is equipped with a HW19710 manual gearbox, offering ten forward and two reverse gears, allowing flexible control across different road and load conditions. Steering is managed through a D50 system, contributing to reliable handling and maneuverability.

The chassis incorporates a MCX16ZG double rear axle with a gear ratio of 4.803, optimized for strong pulling power and fuel efficiency, along with a VGD95 drum-type front axle. It rolls on 315/80R22.5 tires and comes with one spare tire as standard. For trailer coupling, the truck is fitted with a 90# JOST fifth wheel, model JSK39DV1-35, engineered to handle heavy loads safely. The driver cabin is configured as an H77L long cabin with two seats and one sleeper berth, though it does not include factory air conditioning. With a rated loading capacity of 9,500 kg and a speed limit set at 60 km/h, this HOWO tractor is well-suited for medium- to long-haul logistics operations where emission compliance, operating cost savings, and dependable performance are key priorities.
