Weichai: heavy truck power demand high-quality high-powered engine

The development trend of heavy truck power has always been a topic of concern in the industry. Insiders pointed out that high-speed, high-power, heavy tonnage is definitely the direction of future development. If a well-known domestic manufacturer wants to make breakthroughs in the heavy-duty field, it must develop more than 15 tons of heavy-duty vehicles, and the engine power must extend from 230 horsepower to more than 450 horsepower.

In this regard, Wei Dehui, vice president and deputy chief engineer of Weichai Power, believes that large-displacement diesel engines with lower overall fuel consumption, more environmentally friendly and more reliable have become new requirements for China's heavy truck power.

Qi Dehui said that the development of heavy truck power has always been inseparable from the three major themes, namely, power, economy and emissions.

Judging from the current domestic development, the rapid layout of expressways during the “Twelfth Five-Year Plan” period and the rapid popularization of the Internet of Things technology have stimulated the rapid growth of high value-added logistics such as e-commerce express delivery, electronic goods, supermarket cold chain, and health care. The high value-added goods transport means that high-efficiency, high-quality and high-reliability trucks are required. At the same time, as China's foreign trade increases, and the length of international land transport routes continues to increase, the demand for high-end road tractors will also greatly increase.

New market trends and new customer needs are driving the upgrading of heavy truck engines. On the one hand, the trend of “zero inventory” of enterprises is becoming increasingly apparent. Logistics customers are increasingly demanding the punctuality of the arrival of goods; on the other hand, the rapid development of China's logistics industry, high-speed logistics, dumping and transport will become the main form of truck logistics. In addition, in recent years, the country has promoted the use of hanging and transport. A tractor unit is equipped with several trailers. The tractors will be used throughout the day. In particular, with the increase in fuel surcharges and excise taxes, the proportion of fuel costs in transportation costs has been increasing. Therefore, the advantages of integrated low-emission, more environmentally-friendly, and more reliable large-displacement diesel engines have emerged, and have become a new demand for China's heavy truck power.

From the perspective of the development of China's heavy truck power, in 2001, the displacement of major trucks in China was around 7L, rising to 8L in 2003 and rising to 10L in 2009. The share of 12L has risen year by year since 2010. The rising trend of heavy truck engine displacement is very obvious.

However, domestic large-sized transport vehicles with a capacity of more than 500 horsepower are almost entirely occupied by imported vehicles, and the vast majority of home-made high-power heavy trucks are concentrated in more than 300 horsepower segments. The introduction of a high-power and high-performance heavy truck engine has become an urgent requirement for the domestic diesel engine industry.


Weichai Smart Power 13-liter engine

In the field of heavy-duty power technology, Weichai has been cultivating the WP13 for many years. The WP13 engine can output a maximum torque of 2500Nm at 1000r/min. This engine can be used with a smaller speed ratio axle. It is powerful and economical. It is the power of the heavy truck. The best choice.

The climb of the engine to the high-power segment is also in line with the development trend of the international market. From Europe and the United States, the demand for high-power engines has been strong. The development of the US highway network provides a good use environment for long-distance transportation of heavy trucks. The trend of heavy trucking in the United States is obvious. Sales volume of 4-5 (6-9 tons) trucks accounts for not more than one-fifth of the total truck sales. Sales of trucks of grades 6-7 (9-15 tons) account for 1/3 of the total sales. Grade 8 (15 tons or more) sales accounted for more than 1/2 of total sales. The highest tonnage (total cargo weight) of tractors in the United States was 36.2 tons, of which 12-13L engines accounted for 38% of such heavy trucks and 15-16L accounted for 30%.

Europe is affected by geographical and environmental conditions, and trade between countries is dominated by road transport. Since the year of 2000, the European 40t tractor 13L engine has become the mainstream of the market. The 12-13L engine accounts for 64% of the heavy truck. In the 15-16L field, Volvo, Scania, Daimler products have been put on the market, Man, Iveco has also developed. A 15-16L new product will be available to meet market demand.

Judging from the status quo and development of heavy truck power in the United States and Europe, China's heavy trucks (Note: 49 tons for tractors, 55 tons for trucks) have become an inevitable trend.

It is precisely to identify the rising trend of displacement. Weichai has been leading the direction of high-power engines. From the 7-liter machine in 2000 to the 8-liter machine in 2003, it has always been in front of the market. In 2005, the 8-liter machine was At the time when the domestic heavy truck market was respected, Weichai’s 10-liter and 12-liter machines had taken over the market. Thanks to years of precipitation and sublimation of truck power engine technology, Weichai has maintained its lead in sales and share for many years in the field of heavy-duty commercial vehicles. Sheep status. "High-power, large-displacement selection of Weichai" has become one of the principles that many users choose to purchase engines.

"The user's trust comes first from the high reliability of Weichai products." Yu Dehui said: Reliability has always been the main direction of differentiated advantages of Weichai products. Heavy trucks are making money and users are most optimistic about Weichai products. Durable and durable. The average fault interval of the Weichai heavy truck engine can reach 250,000 kilometers, and the life of the B10 can reach 1.2 million kilometers, which is much better than the same series of products at home and abroad, reducing product maintenance time and costs. This account user is the most understandable.

The high reliability comes from the strong technical strength of Weichai. The Weichai IC Reliability Laboratory is the first enterprise key laboratory identified by the Shandong Provincial Department of Science and Technology. It is the most comprehensive and most capable internal combustion engine reliability laboratory in China; and Weichai takes the lead in 19 well-known professional research institutions both at home and abroad (US The International Engine Innovation Alliance for Reliability of Internal Combustion Engines established by the Massachusetts Institute of Technology, the University of Wisconsin, the University of Aachen, Germany, the Southwestern Institute of Technology, Tsinghua University, Zhejiang University, etc., represents the highest level in the world; Weichai is a reliable member of the National Standardization Committee for Internal Combustion Engines. The Leading Unit of the Sex Working Group and the Chairman of the Reliability Committee of the Shandong Internal Combustion Engine Institute can say that the leading and leading units of all internal combustion engine reliability groups can see the presence of Weichai. The reliability of Weichai products is evident in their influence.

Today, with the improvement of technology, the power of domestic truck engines has been generally improved. Whether from the international market or domestic demand, the introduction of Weichai WP13 engine is taking advantage of the trend, with Weichai engine gene this masterpiece, becoming the new darling of the market is expected.
