At present, in the European and American countries where commercial vehicle technologies are leading, some heavy trucks use engines with displacements of 15 litres and 16 liters and power of more than 500 kilowatts. China's heavy truck power is continuing the trajectory of Europe and the United States, accelerating the development of high power. From the current Shanghai Auto Show, the flagship models exhibited by domestic mainstream commercial vehicle companies reflect this trend.
An attendee of Shang Yihong said that the development of China's heavy truck market is the same as in Europe. In the future, domestic high-end heavy trucks will also tend to have large displacements and high power. Large-displacement engines themselves are powerful and have more powerful backup power. Under the same conditions, the heavy truck equipped with a large displacement Engine has a higher running speed than the small displacement engine heavy truck. For example, on a highway, the normal heavy-duty truck operates at a speed of 80 to 90 kilometers per hour, while an engine equipped with 13 liters or so matches an appropriate axle and can reach a speed of 110 kilometers per hour. This is a qualitative leap for heavy-duty trucks. At the same time, it can run more miles. This is the goal pursued by users.
Market demand promotes upgrading of heavy truck products. In recent years, the rapid development of China's logistics industry, high-speed logistics, dumping and transport will become the main form of truck logistics. In particular, in recent years, the country has promoted the use of suspension and transport, and a tractor will be equipped with several trailers. The tractors will be used throughout the day. This requires that the tractor must be highly efficient, safe, and durable, which requires the use of high-power, large-displacement engines.
Over the past decade or so, China’s expressways have advanced by leaps and bounds, and the upgrading of transportation roads has made the truck’s power continue to rise. Now many domestic special purpose vehicles such as special vehicles and mining vehicles require large-displacement, high-power vehicles. At the same time, most of the heavy trucks used by domestic professional transport companies are equipped with high-power engines.
Some experts predict that in the next few decades, the maximum power of trucks in China will reach about 735 kilowatts, and the total automobile mass will reach 100 tons. With the rapid development of science and technology and the expansion of the logistics industry, high-power, large-displacement engines will gradually become the market darling.
