Development trend of heavy truck power has been the subject of concern in the industry, insiders pointed out that the high speed and large power heavy tonnage, is certainly the direction of future development. Domestic well-known enterprises in the production in order to achieve a breakthrough in the field of heavy truck, it is necessary to the development of more than 15 tons of heavy vehicles, the engine power to from 230 horsepower has been to extend to more than 450 horsepower.

对此，潍柴动力副总裁兼副总工程师佟德辉认为，具有综合油耗更低、更环保、更可靠的大排量柴油机已成为中国重卡动力的新需求。

In this regard, Weichai Power, vice president and deputy chief engineer de Hui Tong believes that with lower fuel consumption, more environmental protection, more reliable large displacement diesel engine has become the new demand of China heavy truck power.

佟德辉说，重型卡车动力的发展，始终离不开三大主题，即动力性、经济性和排放性。

Tong Dehui said that the development of heavy truck power, always can not be separated from the three major themes, namely, power, economy and emissions.

从目前国内的发展看，“十二五”期间的高速公路快速布局，物联网技术迅速普及，拉动了电商快递、电子商品、超市冷链、健康医疗等高附加值的物流快速增长。货物运输附加值高意味着需要高效率高质量高可靠性的载货车。同时，随着中国对外贸易的增加，以及国际陆路运输线路长度的不断增加，进而刺激高端公路牵引车的需求量也将大幅增长。

From the current development of the domestic, "1025" during highway fast layout and fast popularization of Internet of things technology, pull the electricity supplier delivery, electronic goods, supermarket cold chain, health care and other high added value logistics rapid growth. The high value of freight transportation means high quality, high reliability and high reliability. At the same time, with the increase of China's foreign trade, as well as the increase in the length of the international land transport line, and thus stimulate the demand for high-end road tractor will also be a substantial increase in demand.

市场新趋势和客户新需求在促进重卡发动机升级换代。一方面，企业“零库存”趋势日趋显现，物流客户对于货物到达的准时性要求越来越高；另一方面，我国物流行业高速发展，高速物流、甩挂运输将成为卡车物流的主要形式。另外近几年国家推广甩挂运输，一辆牵引车配好几辆挂车，牵引车将全天候使用。特别是随着燃油附加税、消费税的上升，燃料成本占运输成本的比例越来越高。因此，综合油耗更低、更环保、更可靠的大排量柴油机优势显现，已成为中国重卡动力的新需求。

The new trend of the market and customer demand in the promotion of the new heavy truck engine upgrade. On the one hand, enterprises "zero inventory" trend is becoming more and more obvious, logistics customer for the arrival of the goods at the time request more and more high; on the other hand, the rapid development of China's logistics industry, logistics rapid, rejection hang transport will become the main form of the logistics of the truck. In addition, in recent years, the country to promote the spread of the transport, a tractor with several trailers, tractors will be used around the clock. Especially with the increase of fuel tax, consumption tax, fuel costs accounted for the proportion of transport costs more and more high. Therefore, comprehensive lower fuel consumption, more environmental protection and more reliable large displacement diesel engine show the advantages has become the new demands of Chinese heavy truck power.

从中国重卡动力的发展来看，2001年，中国重卡主要车型排量在7L左右，2003年上升至8L，2009年上升到10L。2010年以来12L的占有率逐年上升。重卡发动机排量的上升趋势十分明显。

From the point of view of the development of China's heavy truck power, 2001, China heavy truck main models of displacement in 7L around, in 2003 rose to 8L, 2009 rose to 10L. Since 2010, the share of 12L has increased year by year. The rise of heavy truck engine displacement is very obvious.

然而国内500马力以上的大件运输车几乎全被进口车所占据，而国产大马力重卡绝大多数都集中在300多马力段，推出一款大功率高性能重卡发动机成为国内柴油机行业迫切需求。

However the more than 500 horsepower of large trucks almost all were imported cars occupied, and homebred high-powered heavy trucks most are concentrated in more than 300 horsepower segment, to launch a high power high performance heavy truck engine has become the urgent needs of the domestic diesel engine industry.

在重型动力技术领域深耕多年的潍柴，当仁不让地担起了这一重责，适时推出了13L发动机。实验表明，这款WP13机在1000r/min就可输出最大扭矩2500Nm，此发动机可搭配更小速比车桥，动力性强，经济性好，正是重卡动力的最优选择。

In the field of heavy dynamic technology for many years cultivating Weichai, make no apology for having shouldering the this heavy responsibility, the timely introduction of 13L engine. Experimental results show that this WP13 machine in the 1000r / min can output maximum torque count leads, the engine can be paired with a smaller ratio bridge, strong power, good economy is best choice for heavy truck power.

发动机向大功率段攀升，也符合国际市场的发展趋势。从欧美国家来看，对大功率发动机的需求一直旺盛。美国高速公路网发达，为长途运输的重卡提供良好使用环境。美国卡车重型化趋势明显，4－5级(6-9吨)卡车销量占卡车总销量不超过1/5；而6—7级(9-15吨)卡车的销量占总销量的1/3；8级(15吨以上)产品的销量占销售总量的1/2以上。美国牵引车的最高吨位(车货总重)为36.2吨，其中12-13L发动机占此类重卡的38%，15-16L占30%。

The engine to the high power segment, also in line with the development trend of the international market. From the European and American countries, the demand for high power engines has been strong. The United States developed highway network, provide a good environment for long-distance transport of heavy truck. The heavy truck trend is obvious, 4-5 (6 9 tons) truck sales accounted for total sales of trucks was less than 1 / 5; and six - level 7 (9-15 tons) truck sales accounted for one-third of the total sales volume; grade 8 (15 tons) of the product sales accounted for half of the total sales of more than. The highest tonnage tractor (the total weight of goods vehicles) is 36.2 tons, which accounted for 38% of the heavy truck engine 12-13L, 15-16L accounted for 30%.

欧洲受地理环境条件影响，各国间的贸易方式以公路运输为主。2000年以来，欧洲40t牵引车13L发动机已经成为了市场的主流，12-13L发动机占重卡比重达到64%；在15-16L领域，Volvo，Scania，Daimler产品已投放市场，Man，Iveco也已开发出15-16L的新产品，以适应市场需求。

Europe affected by the geographical environment, the way of trade between countries to road transport based. Since 2000, the European 40t traction vehicle 13L engine has become the mainstream in the market, the proportion of the heavy truck engine 12-13L reached 64%; in the field of 15-16L, Volvo, Scania and Daimler products have been put on the market, new products of man, Iveco has also developed 15-16L. In order to meet the market demand.

从美国及欧洲重卡动力的现状和发展来看，中国的重卡(注：牵引车的标载49吨，限重55吨)发动机排量上升趋势成为必然。

From the point of view of the present situation and development of American and European heavy truck power, China's heavy truck (Note: traction vehicle load 49 tons, limit and weighing 55 tons) rising displacement engine become inevitable trend.

正是认准了排量上升的趋势，潍柴一直引领着大功率发动机的方向，从2000年的7升机到2003年的8升机，从来都走在市场前面， 2005年8升机被国内重卡市场推崇之时，潍柴的10升机、12升机已独步市场，得益于对卡车动力发动机技术多年的沉淀和升华，在重型商用车领域，潍柴多年保持销量和份额的领头羊地位。“大功率、大排量选潍柴”已经在潜移默化中成为许多用户选购发动机的原则之一。

Is adhered to the displacement of rising trend, Weichai has been leading the direction of high power engine, from 2000 7 liter engine to 2003 8 liters machine, never walk in the front of the market, 2005 8 liters of machine is the domestic heavy truck market respected, Weichai 10 liters machine, 12 liter engine has unmatched Market, thanks to the truck engine technology for many years, the precipitation and distillation, in the field of heavy commercial vehicles, Weichai years keep the sales volume and market share leader status. "High power and large capacity of selected Weichai" has become one of the principles of many users to buy Engine imperceptibly.

“用户的这份信任，首先来自于潍柴产品的高可靠性。”佟德辉介绍说：可靠性一直是潍柴产品差异化优势的主攻方向，重型卡车是赚钱工具，用户最看好潍柴产品的皮实耐用。潍柴重卡发动机平均故障间隔可达25万公里，B10寿命可达到120万公里，大大优于国内外同系列产品，减少了产品维修保养时间和费用，这个账用户算得最明白。

"The user's trust, high reliability first comes from Weichai products." De Hui Tong said: reliability has been the main direction of Weichai product differentiation advantages, heavy truck is a tool to make money, users are most optimistic about Weichai products of Pishi durable. Weichai heavy truck engine mean failure interval of up to 25 million km, the B10 life can reach 120 000 km, greatly superior to the outside of the same series of products, reducing the product maintenance time and cost, the account of the user can be regarded as the most to understand.

而高可靠性来自于潍柴强大技术实力的支撑。潍柴内燃机可靠性实验室是山东省科技厅认定的首批企业重点实验室，是国内功能最全、能力最强的内燃机可靠性实验室；潍柴牵头19家国内外知名专业研究机构(美国麻省理工学院、威斯康辛大学、德国亚琛工业大学、美国西南研究院、清华大学、浙江大学等)成立的内燃机可靠性国际技术创新联盟，代表了国际最高

The high reliability from Weifang strong technical strength support. Weichai engine reliability laboratory is Shandong Province Science and Technology Agency finds that the first batch of Key Laboratory of enterprises, is the country's most versatile, the strongest internal combustion engine reliability laboratory; Weifang led 19 well-known professional research institutions (Massachusetts Science Institute, University of Wisconsin, University of Aachen, Germany, Southwest Research Institute, Tsinghua University, Zhejiang University) was founded on the reliability of internal combustion engine international technology innovation alliance, representing the highest international
