With the development of the economy and changes in market demand, the world heavy truck industry has shown a trend of development with large tonnage, high horsepower, lightweight, and high technology. In order to win the upper hand in the future market competition for high-powered heavy trucks, in 2011, the Shaanxi Automobile Engineering Research Institute organized technical personnel to carry out the research and development work on the super horsepower Shanxi Automobile Delong F3000 IV tractors.
Under the utmost support of relevant departments, Shaanxi Automobile R&D and trial production personnel have worked through intense and orderly work to overcome a series of technical problems. In recent days, the domestically-developed maximum horsepower tractor SX4257NZ324 has been successfully developed. The vehicle is powered by 13L turbocharged intercooled and high pressure common rail electronic fuel-controlled diesel engine newly developed by Weichai Power. It has a maximum power of 550 horsepower and a maximum torque of 2300N.M. It is the most powerful engine in the country. At the same time, the engine's emissions have reached the national IV requirements.
Shaanxi Automobile SX4257NZ324 adopts DeLong F3000 variable cross-section lightweight frame, Hande 469 single-stage drive axle, few front and rear leaf spring suspensions, lightweight vacuum tires, six-channel ABS anti-lock braking system, and tailor-made water cooling system. The exhaust system makes the SX4257NZ324 superior in weight, power, fuel efficiency, and safety compared to other tractors.
At present, in the field of large-horsepower logistics and transportation, imported heavy trucks occupy a dominant position. The launch of the 550-hp tractor tractor from Shaanxi Auto Delong will inevitably make Shaanxi Auto the leader in domestic high-powered transport vehicles.
