Raise engine level to new height
Since the Production Line that was co-operated with MAN MAN in 2010, Sinotruk’s engine manufacturing capacity has been significantly improved. In terms of technology, China National Heavy Duty Truck's MC11, MC13 and other engine emissions can reach the Euro 5 standard. At present, Europe is about to implement the Euro 6 standard, and China National Heavy Duty Truck has the ability to produce Euro 6, and the full implementation of the Euro 6 standard in China is expected to By 2020, China National Heavy Duty Truck has achieved at least 5 years of technological leadership in this area; if workers want to do a good job, they must first sharpen their tools. In terms of manufacturing, China National Heavy Duty Truck fully introduces 5 companies with the same Machining and casting production lines, which fully reference MAN manufacturing standards in the machining of components such as cylinder blocks, cylinder heads, crankshafts, and tug covers, are fully automated at the manufacturing level, and will use intelligent equipment with “Industry 4.0†features Among them, key parts use two-dimensional codes to implement single-piece management and record quality files. In the finishing process, the machining center can automatically identify the size of the workpieces, modify the processing parameters, and get a qualitative improvement in automation, data, and intelligent production. In the process, China National Heavy Duty Truck also achieved a breakthrough, the previous engine used materials It is gray cast iron. The tensile strength of gray cast iron is 250-280. After the introduction of new technology, heavy-duty steam uses its own vermicular cast iron, the tensile strength is increased to 500, the elastic modulus is increased by 40%, and the fatigue strength is increased by 100. %, Material changes have created conditions for engine performance improvement. The cylinder body and connecting rod adopt the most advanced breaking process in China, which has low processing cost, reliable positioning, and greatly improved the life of the diesel engine. The use of the new-generation BOSCH fuel system and the use of fuel lubrication fundamentally eliminated the hidden dangers of oil and fuel mixture. The unique design of the cylinder block and cylinder head reduces noise and reduces the friction loss of the valve train and eliminates leakage and leakage failure of the cylinder head gasket.

In the words of Guo Hua, Assistant General Manager of CNHTC Jinan Dynamics Division and Manager of MC Processing Department, he said: “Since the cooperation with German MAN company, Sinotruk’s engine has achieved a qualitative leap in terms of technology, manufacturing, and technology. Not only did it significantly widen the gap with domestic brands, but it also made CNHTC's engine reach the top level in Europe, which also provided ample impetus for heavy-duty trucks.
Looking for quality lubricants to help the engine perform optimally
A good engine is the core of efficient transportation of heavy trucks, and an important help for the performance advantages of the heavy truck powertrain system is lube oil. High-quality lubricants can increase the efficiency of the engine, extend the life of the engine, reduce the frequency of vehicle maintenance, and reduce the cost of logistics companies.
When the heavy-duty engine is running, high-quality lubricating oil can better realize the low-rotation and high-torque pulling force of the engine. The heavy-duty MC11 maximum torque is 2100Nm, the MC13 maximum torque is 2500Nm, the maximum torque-rotation range is wider, and the torque reserve coefficient is more Big, when the fuel consumption is synchronised, speed leadership is achieved, making it easier for the driver to drive. High-quality lubricants have highlighted the leading performance of high-quality engines in the logistics industry, helping heavy-duty trucks to consume less fuel in transportation and greatly saving costs.
In the maintenance of the powertrain system for heavy trucks, the care of high-quality lubricants and oils is also very significant. The three powertrain systems of the engine, gearbox and axle are the most frequent components for reciprocating motion. Lubricating oil and oil provide highly efficient lubrication and cooling. When the gasoline in the engine is burning, the piston reciprocates and generates very high heat. If it is subjected to heat burning for a long time, the power system will be seriously damaged. At this time, the engine oil is injected to the piston to take away the heat of the piston in a short time. The lower the engine temperature and the longer engine life, the better the oil quality is, the more pronounced the cooling effect of the engine will be, and the longer the service life of the engine will be. In addition, geared lubricants can also reduce wear on components such as gears in gearboxes, quickly taking away frictional heat, allowing components to run softly and cool quickly to maximize performance. Good, extend the life to the longest.
Lubricant maintenance of the power system has reduced the frequency of logistics transportation vehicles entering the maintenance workshop and greatly enhanced the vehicle's on-time operation time. Chairman Hu Bokang of China National Heavy Duty Truck (Hong Kong) Co., Ltd. Jinan Power Division introduced: “According to China National Heavy Duty Truck Co., Ltd. According to data, Sinotruk's engine is equipped with high-quality lubricants, which can achieve an oil change of 100,000 kilometers on the standard expressway, while the use of general oil products requires a replacement of about 20,000 to 10,000 kilometers. Maintenance cycle saves vehicle maintenance costs.For example, by replacing hydraulic pump oil with Shell Tellus S2 M46, CNHTC can double the oil change time and save $15,644 in cost. The reliable oil quality guarantee allows us to make commitments to the user of 1.5 million kilometers of overhaul and 100,000 kilometers of maintenance without maintenance.In addition to Tellus hydraulic pump oil, other lubricant products are also very effective. And the high-quality engine realizes mutual promotion and complement each other."

Provides efficient protection for the logistics industry
According to Hu Bokang, Chairman of the Board, this year, Sinotruk Engine Company achieved a production and sales volume of 25,000 units, and it is expected that it will achieve the goal of 60,000 units in 2017. At the annual meeting of JAC Geerfa business, the company introduced a brand new product from CNHTC. The improvement in the performance of CNHTC's engine not only has the quality of the truck, but has also become the benchmark for the entire industry.
Nowadays, in the period of rapid development of the logistics industry, the engine of the heavy truck truck is becoming more and more important as the driving force of the development of the logistics industry. Due to the timeliness requirements of the logistics industry, low failure rate requirements, comfortable and safe driving performance requirements, and environmentally friendly vehicle emission standards are all testing the technical level and manufacturing level of heavy truck companies.
In the face of the new requirements of the logistics industry, China National Heavy Duty Truck has gradually invested several billion yuan in the development and manufacture of engines, which has effectively promoted the improvement of the quality of China National Heavy Duty Trucks. The powerful engines have continuously updated their records under the care of lubricants. The speed of 90 kilometers does not decrease, 1.5 million kilometers are not overhauled, and 100,000 kilometers are maintenance-free. At the same time, the engine performance is improved. The engine quality is also reduced by 100 kg, which promotes the lightweighting of vehicles and creates new possibilities for the logistics industry's Dora run. .
