As a core element influencing the performance and quality of heavy trucks, research and development and manufacturing of heavy-duty diesel engines has been a common area of ​​exploration for China’s leading diesel and truck companies. How to make up for the gap between China's autonomous power products and international famous brands in terms of technical content and product quality, how to meet the changing needs of Chinese users at a lower cost, and to break through the bottleneck of the lack of high-end products in China's autonomous diesel engines, is in recent years Focused on the development issues of the industry.
As the earliest and largest truck manufacturing company in China, FAW Liberation has taken an important responsibility in its own development and in driving the development of the national automotive industry. In 2008, FAW produced a series of advanced CA6DM engines with advanced R&D capabilities and advanced manufacturing technologies that lasted three years. This has become a major breakthrough in the development of FAW's liberation and heavy-duty development. From the CA6DL engine with the first four-valve fuel-saving technology to the CA6DN engine with the highest domestic power, FAW Liberation has spared no effort in the independent research and development of heavy-duty diesel engines, creating numerous technological achievements that have made the industry remarkable. Accompanied by the listing of the CA6DM engine, the market coverage and product competitiveness of the liberation of heavy platforms will achieve a qualitative leap. As a gold displacement engine suitable for China's national conditions, the liberation CA6DM series products fully integrate the individual needs of Chinese users, and have significant advantages in terms of technical content, dynamics, economy, and regulatory compliance, driven by the CA6DM power. The market performance of liberation of heavy platforms is worth looking forward to.
Leading technology, parcel international
Bid farewell to the old "Double Valve" and "Side-on camshaft", the first domestic heavy-duty diesel engine adopting an overhead camshaft four-valve structure and symmetrically-structured cylinder block, and CA6DM, a new-generation 11-liter diesel engine independently developed by FAW. The advent of the undoubtedly is to cast a heavy bomb in the highly competitive heavy truck market in China. The CA6DM series engine is a diesel engine that was completely developed by FAW and has truly reached the world's advanced level. It has been highly evaluated by European and American engine experts. It can be said that CA6DM has a pure Chinese lineage and is a truly "Chinese core."
This engine has three invention patents and five utility model patents such as the independently developed engine brake technology and cylinder head double water jacket design, and adopts an integrated cooling and filtration modular design. The four-valve technology of the overhead camshaft adopted successfully implanted the car technology, directly advancing the advancement of China's independent research and development engine technology, realizing the integration of Chinese engine technology and world advanced engine technology, and tailoring it to heavy commercial vehicles. The perfect engine to build.
Power: Safe, Reliable, Efficient Fuel Saving
The power of the CA6DM engine covers 370-420 horsepower. The most advanced overhead camshaft roller structure technology is used to make the engine more reliable and more tolerant. In addition, the life of this engine B10 is as high as 1 million kilometers, establishing the highest standard of domestic heavy truck engine life.
The starting torque of this model is increased by 30% compared with the same power engine, and the maximum torque is increased by 10%. Accelerated transient response is good, and the acceleration time is short, making it easier to start and accelerate overtaking. After rigorous experiments, the heavy-duty tractors that match the CA6DM engine are more sensitive to gear shift acceleration under full-load conditions, and their operating efficiency has increased dramatically.
CA6DM uses an integrated brake independently developed by Liberation. The overall performance is good, the braking power is large, and the brake responds quickly. It is the only engine developed by China to adopt the compression and release braking method. Compared with the conventional deflation brake, the brake power is increased by 34%, and the brake is safer when the whole vehicle is under heavy-load downhill, and the heavy-duty safety can be easily achieved. Reduces brake shoe wear and reduces the frequency of replacement. At the same time, when the engine is braked, it is in the off-oil state, which can greatly reduce fuel consumption and save a lot of use costs.
CA6DM continues the fuel-saving characteristics of the liberation of the CA6DL four-valve engine, supporting the German BOSCH company's mature electronically controlled common rail system, high injection pressure, good fuel atomization, and more complete combustion; the highest burst pressure of 200bar, 20% higher than other products, High explosive pressure, fundamentally solve the problem of fuel economy.
Liberate the heavy truck platform and fully upgrade its power
Reliable, powerful, fuel-efficient, and safe, the excellent performance of the CA6DM engine is reflected in all aspects. This engine will be matched with models such as Liberation J6 and Aowei. The benefits to users will be considerable.
"High-efficiency energy-saving" has always been the core value of the continuous improvement of international engine R&D applications. Compared with the previous heavy-duty truck products, Liberation CA6DM has greatly upgraded "high-efficiency energy-saving", not only when it adapts to ordinary road conditions but also shows excellent performance in complex road conditions. Under operating conditions, the CA6DM engine has significant advantages in fuel economy and high speed. The perfect combination of 370-420 horsepower and 11 liters can show high speed, high efficiency and high profitability in all kinds of complex road conditions in China. The liberation truck equipped with this engine will open up new energy-saving and profitable models for users.
The advent of the CA6DM engine has greatly increased the market competitiveness of the liberation of heavy platforms and improved the liberation of heavy-duty engine product series, so that liberation can truly meet the needs of Chinese heavy truck users. It not only marks FAW's level of development, development capabilities, and development tools to a new level, but also marks that FAW's independent innovation capability and independent innovation system are gradually maturing. Accompanied by the constant expansion of the liberation of heavy-duty product lines and the overall upgrade of product technology and quality. FAW Jiefang’s position as a leader in the domestic truck industry will be further consolidated.
At the upcoming 13th Shanghai International Automobile Expo, the Liberated J6P-370, 390, and 420-hp heavy-duty tractors equipped with CA6DM engines will be launched. The latest masterpieces for the liberation of heavy platforms will be reviewed by customers at home and abroad. Let us jointly look forward to the CA6DM engine's power to promote customers to rely on efficient heavy-duty truck products and healthy operating models to meet the low market environment and create greater operating efficiency.
