The current transportation market is undergoing unprecedented changes. The demand for efficient transportation by transporters is increasingly highlighted, and more attention is paid to the performance of vehicles in terms of power and fuel consumption.

In October 2022, Master Hu from Shuyang County, Suqian, Jiangsu Province, said that he usually pulls bulk cargo from Zibo, Shandong Province. He is driving a new heavy truck Shandeka G7S, equipped with WP14T 610 high-power engine. He told Transporter. com: "The sense of power brought by high horsepower is a new experience that has never been seen before."

In addition to strong acceleration when overtaking, high horsepower models are also characterized by fuel economy. According to the screenshot on the Smart Heavy Truck APP after the daily operation of Master Hu, the fuel consumption per hundred kilometers is only 25.7L, realizing a real sense of high horsepower without fuel consumption.

On August 22, 2022, the whole series of heavy trucks equipped with Weichai Power T series high-power high-end products appeared on the market, and it took less than half a year to achieve sales of more than 10000. Recently, the annual sales volume of 13L and above high-power heavy trucks of China National Heavy Truck Corporation exceeded 10000, ranking first in the domestic market segment of high-power heavy trucks.

Weichai T series high-power engine is the exclusive power tailored by Weichai Power for CNHTC. With the application of the world's first commercial diesel engine platform product that has exceeded 51% thermal efficiency, it has the advantages of strong power, high efficiency, energy conservation, stability, reliability, quiet and comfort. It is specially matched with the heavy truck type, which has achieved comprehensive improvement in power performance, reliability, thermal efficiency and fuel economy.

Efficient and reliable Weichai WP14T engine

WP14T engine, as one of Weichai's flagship high-power engine products, is also the key for HTC to achieve such success. The engine adopts the world's first diesel engine platform technology whose thermal efficiency exceeds 50%, covering the 560 horsepower to 610 horsepower segment. The maximum torque is 2600 Nm to 2750 Nm, and the peak torque can be output at 900 to 1400 rpm. With high torque at low speed, overtaking on slopes is faster. It is easy to cope with mountainous, Gobi, hilly and other terrain, and has stronger adaptability to road conditions.

According to the test, when the WP14T engine is driving at an altitude of 4100 meters or more, the torque increases very fast during 700-1000 revolutions. At 1200 revolutions, the torque is about 10% higher than that of competitors at the same level. Even the plateau can be easily handled, and one car can travel all over the country.

At the same time, thanks to the support of the high thermal efficiency platform, the WP14T engine's explosive pressure reached about 230 bar, the heat transfer loss was reduced by 40%, the minimum fuel consumption rate was 4% lower than that of competitors, and the comprehensive fuel consumption was reduced by more than 2L per hundred kilometers, fundamentally reducing the cost of transport vehicles.

In addition, WP14T engine adopts a unique crankshaft offset design, low elastic piston rings, antifriction coating bearing shells, low viscosity Weichai special lubricating oil and high temperature oil thermostat, and is equipped with a high-precision intelligent cooling system to reduce wear in many ways and improve service life. Its brake power has reached 350kW, B10 service life has reached 1.8 million kilometers, and has passed more than 60 bench tests for more than 20000 hours, More than 50 items of plateau extreme cold environment verification have accumulated over 1.8 million kilometers, bringing users lower operating costs and a more reassuring operating experience.

It is worth mentioning that in order to further improve the operation efficiency and bring a comfortable driving environment for the transport people, the WP14T engine has also applied lightweight design. Through the optimization of materials, processes and other aspects, the total weight of the WP14T engine is as low as 999kg, which is about 50kg lighter than similar 13L engines in China. In addition, the cylinder head cover with full suspension damping design, the reinforced cast aluminum flywheel housing, and the cylinder block strength are improved, The engine noise is reduced and the working environment is more comfortable.

Weichai has joined hands with CNHTC to achieve data synergy, accelerate product upgrading, constantly break the engine thermal efficiency record, create a benchmark product with high horsepower and low fuel consumption in the global power field, and constantly bring more outstanding products to the transportation industry.Editor/Xing Wentao
