Use the "core" to do a good job in the national six products FAW Jiefang Engine Division to help the industry upgrade

In 2019, as the first year of marketization of commercial vehicle country six products, major commercial vehicle companies have made great strides at the 18th Shanghai International Automobile Industry Exhibition, attracting media attention and users' favor, thus enabling commercial use. The topic of Cheguoliu continued to heat up, occupying the headlines of the industry and becoming a “flow topic”. As the engine head enterprise of the core components of commercial vehicles, FAW Jiefang Engine Division (hereinafter referred to as the Business Division) has the responsibility and obligation to help the commercial vehicle industry upgrade to the national six industries.

The business unit's forward-looking strategic layout of the national six engine research and development, the use of innovative technology to enhance the performance of the national six engine, with the ultimate test to empower the national six engine value, to help upgrade the commercial vehicle industry. In the critical moment of seizing the market, we will do a good job in the "National Six" products from the "core", and truly achieve the "core" with the users.

Forward-looking strategic layout of the National Six Engine Development

The business department adheres to the philosophy of “individual innovation leads the market” and develops a research and development technical team of 1,200 people, focusing on high-end diesel engine research and development, natural gas product research and development, non-road product research and development, alternative fuel and new energy technology development, and research and development of independent high voltage. Common rail system.

The National Sixth Engine, which is led by the business unit, not only consolidates the status of the industry, but also continuously promotes the upgrading of the commercial vehicle industry to the national six. Up to today, the business unit has a wide range of products such as Aowei, Hengwei, Conway, Jinwei and Dachai. Its six-stage diesel engine has a displacement of 2 to 13 liters and a power range of 110 to 560 hp. Covering from 5 liters to 13 liters, the power range is from 220 hp to 470 hp. The products are abundant and meet the needs of heavy, medium and light vehicles. Among them, it is worth mentioning that the asymmetric turbocharger with independent intellectual property rights independently developed by the business unit has reached the latest level of similar foreign-invested products, with high-speed fuel consumption and low-speed fuel consumption, which has won the consensus of experts in the industry. Recognition.

Enhance the performance of the National Six engine with innovative technology

Under the wave of energy conservation and emission reduction, the business unit actively embraces change and meets new challenges. In the development stage of the country's six products, we strived for breakthroughs in product performance, overcome multiple technical difficulties, and achieved innovative breakthroughs in multi-category technologies.

Aowei CA6DM3 engine

At the first “China Source Power” expert review meeting, Xichai CA6DM3 Guoliu Engine won the honorary title of “China Source Power·Energy Pioneer” and “China Source Power·Brand Pioneer”. CA6DM3 country six engine adopts CEGR+DPF+SCR mainstream technical route and FAW distributed low pollution high efficiency combustion technology, equipped with FAW independent high voltage electronic control system and proprietary electronically controlled asymmetric supercharging technology, which can achieve maximum torque of 2600N·m. The lifting torque is up to 208N·m, the thermal efficiency is up to 46.5%; the special cam engine braking technology, the braking power is more than 300kW; the high-strength and high-heat-resistant creeping iron cylinder head and the world's first laser-welded steel piston technology realize high explosion pressure, High efficiency; at the same time, CA6DM3 engine production consistency is stable, the emission margin is more than 20%; compared with the same type of engine, it can save more than 3% of fuel, the urea consumption ratio is lower than 3%, and the product performance has reached the international advanced level.

The ultimate test of the national engine value

The business unit always takes the user value as the core and empowers the commercial vehicle products with higher reliability. The engine of the National Sixth Engine has repeatedly simulated the actual scene test, and through a large amount of data research and comparison, the new product has been modified and improved to ensure the reliable operation, safety and power of the product.

From the end of 2018 to the beginning of 2019, in order to ensure the working condition of the National Six engine in the high-cold environment, the winter calibration team of the business department conducted a high-cold calibration work for more than 40 days and nights on the National Sixth model, constantly igniting the engine and checking the engine sensor. And the actuator and reading parameters become the daily work of front-end testers. In addition to the alpine test, the company's National Six engine products also carried out a plateau calibration test in Qinghai Golmud, completing the supercharger of Jinwei 4DB1-11E5 and Jinwei 4DB1-13E5 at 3500 meters, 4000 meters, 4500 meters and above. Protection test, hot car start test, regeneration temperature model verification test.

National Six-model Plateau Experiment

With the advent of the sixth era of commercial vehicles, the engine is the core of communication users. The business unit has always adhered to lean operation, continuously promoted the development of technological innovation, and adhered to the independent research and development concept of leading the market. Especially in the research and development of the country's six technologies, the business unit insists on cultivating high-end advantages, and upgrades the commercial vehicle industry with the national advanced level of the international advanced level, empowering users with higher value.
