Heavy truck industry cooperation frequency reality for the engine battle?
With the implementation of the fuel tax and the strong protection of the over-control policy, the domestic heavy truck has achieved unprecedented development. It is estimated that the sales of heavy trucks will exceed 700,000 in 2010. It is expected that in the next five years, China’s heavy truck sales will exceed the one million mark and become the highest in the global heavy truck sales.
From the current analysis of the existing heavy trucks in Europe and the United States, the future heavy trucks will develop towards heavy, high power and low fuel consumption. This will make heavy-duty trucks move toward low emissions, lighter weight, and high-tech equipment. In recent years, the mainstream heavy-duty truck engines in the European market have exceeded 700 horsepower and the torque also exceeds 3000 N·m, through CR EGR DOC (electronically controlled common-rail exhaust gas recirculation particulate catalytic oxidizer), DPF (particulate trap) and SCR (Selective catalytic reduction), 2ST (secondary pressurization), VGT (variable geometry turbocharger) and other technologies enable engine emissions to meet Euro V. It is predicted that in the next 10 years, the maximum power of foreign trucks will reach 735 kW (1000 hp), and the total vehicle mass will reach 100 tons. Diesel engines will also adopt more advanced fuel injection systems and new catalytic particulate filters to meet more stringent environmental regulations in the future.
With the joint venture of China and foreign engine companies and the introduction of technology, and the continuous improvement of the engine technology level, our truck companies have taken precautions and the power of their engines has been generally improved. In 2001, the engines of the domestic truck main models were mostly naturally aspirated. The maximum power was only 180 horsepower. In 2002, the boost of turbocharger technology increased to 240 horsepower. In 2003, the intercooler was added and further improved. 280 horsepower; By 2010, this figure has reached 300 to 400 horsepower. In the next two years, the domestic heavy truck power will generally be upgraded to more than 400 horsepower, and the engine displacement will be more than 10 liters.
The firestorm in the domestic heavy-duty truck market led to the acceleration of technical upgrading of domestic commercial vehicle companies. At the same time, it led to the joining of a number of heavy trucks and new troops. The emergence of new faces such as the Grand Canal Heavy Truck, Guangzhou Automobile Hino, and Jirui Heavy Trucks made the heavy truck industry more competitive. More intense. In the entire heavy truck competition, the status of the engine is crucial. The engine's technical barriers are relatively high, and research and development are difficult. If there is no brand guarantee, it will be more difficult to obtain the user's approval. Therefore, in the entire heavy truck industry chain, the engine level will restrict the improvement of the vehicle's quality. In recent years, the cooperation between Sinotruk and German Mann, Beiqi Foton and Mercedes-Benz, JAC and Navistar has both included large-horsepower engine projects, which is enough to see the hunger and thirst level of engine resources of domestic heavy truck companies.
In the future, the development of domestic logistics will inevitably be considered from the perspective of reducing transportation costs. With the further development of heavy-duty, the demand for high-power, low-fuel-consuming heavy-duty truck engines will increase. At present, domestic engine manufacturers have developed large-horsepower engines, such as Yuchai's 13-liter YC6K engine, and its maximum power has exceeded 500 horsepower; Weichai Power's 12-liter engine covers a wide range of 240 to 480 horsepower, and 13-liter engines will also In the near future, Dongfeng Cummins' newly developed 13-liter ISZ engine not only achieves a power of 545 horsepower, its emissions can meet Euro III, Euro IV, and can be further upgraded to Euro V; FAW Xichai launched a 13-liter 6DN engine. Currently, there are 460-horsepower liberation J6 tractors loading announcement; Sinotruk and German Man's full cooperation, so that China National Heavy Duty Truck has D26 and D20 engine technology, currently its D20 engine has been in China National Heavy Duty Trucks The tractors were loaded on vehicles; in cooperation with Mercedes-Benz, Beiqi Foton had a Mercedes-Benz 12-liter OM457, which will be used on Auman’s fourth-generation truck GTL; Navistar signed the contract, but now there are already Navistar's 10-litre NGD9.3E engine assembled on the Gehlfacht heavy truck. In the future there will be a larger displacement of the Navistar engine in Goel. The heavy truck.
In addition, important components on the engine, such as the electronic control system and post-processing systems are also indisputable. Domestic engine companies have cooperated with German Bosch and Delphi components giants to further accelerate the upgrading of domestic engine technology. Under the premise of joint ventures of domestic heavy truck companies, independent engine suppliers in China will seek more ways to enhance their competitiveness, which will indirectly increase the quality of future heavy trucks in China.
