In particular, in the face of the R&D and launch of the National Sixth Engine, what improvements have been made? To this end, China Truck Network interviewed Lu Lin, Assistant General Manager of Hualing Xingma (Group) Co., Ltd.

At the mid-2019 meeting, Hualing Xingma exhibited six 8-13L engines, including two 12-liter Hanma Guoliu power and a 10-liter Hanma Guoliu power. "In 2019, not only did we have a 10 liter 12-liter engine, we also officially launched a new platform engine with an 8 liter, 11 liter, and 13 liter displacement, which makes our National Six engine product platform more complete."
Lu Lin told reporters that the Hanma power engine was officially launched in 2012. At that time, only the 10L and 12-liter diesel engines could meet the emission levels of the National 3 and the National 4, and quickly gained the advantages of high reliability, low speed and high torque. Recognition by market users.
In 2015, 10 liters and 12 liters of natural gas engines were launched, and production and sales increased significantly. In 2016, production and sales reached 10,000 units. In 2017, the company launched the National Five engine, which further reduced fuel consumption and continued to increase production and sales. At the same time, the first national six engine Successful ignition.

What are the improvements and upgrades of the Hanma 6 engine?
“After three and a half years of preparation and research and development, Guoliu products have completed all development and verification work, and obtained announcements, which have the conditions for listing and sales. The reason why Guoliu products spend so much time is because of many improvements. And upgrade."

Lu Lin gave an example. First, the DPF system was added to effectively reduce particulate matter. At the same time, more efficient SCR technology and advanced control system were adopted to ensure that the engine can meet the requirements of the national six emission under any working conditions.
The second is to greatly improve the reliability and durability of the engine. Through a large number of experiments and verification, the life of B10 exceeds 1.6 million kilometers, and the design of the whole machine has been improved, including the improvement of the cylinder block, cylinder head and friction payment of the whole machine, which makes the whole machine better. Durability.
The third is to make improvements related to reducing fuel consumption. Optimized and matched to the entire combustion system, using a more efficient turbocharger system, using an advanced two-channel EGR system to ensure emissions while reducing fuel consumption.

Lu Lin believes that through the improvement of the above three aspects, the Hanma Guoliu engine can withstand the test of the market at the technical level, coupled with the corresponding independent research and development of gearboxes and axles, forming a “golden power chainâ€. Hanma Powertrain and vehicle products will have strong market competitiveness.

What are the “secrets†of Hanma Bridge?
Then, what breakthroughs did Hanma Axle achieve in promoting independent research and development? In this regard, China Truck Network interviewed Cheng Jinjin, executive deputy general manager of Anhui Hualing Automobile Co., Ltd. Axle Branch.
Cheng Jinjin introduced that since its establishment in 2006, Hanma Axle has developed 3.5T-7.5T steering front axle and 7T-16T single-stage reduction drive axle after more than ten years of continuous digestion and absorption of mainstream heavy-duty axles at home and abroad. The wheel axle deceleration drive axle and off-highway mining axles, the steering axles and drive axles of all kinds of platforms basically cover all heavy commercial vehicles.
At the mid-term business conference in 2019, Hualing Xingma exhibited three Hanma axles.
For more than ten years, Hanma's axles have grown from nothing to good, and what are the precipitations and achievements in this process?
“One is the standardization of parts, the generalization of components, and the serialization of products.†Cheng Jinjin said that Hanma Axle adheres to the use of typical components that are in the leading position in the industry, and achieves serialization or deformation of the drive axle products by different combinations of design methods and production methods. Purpose, or strive to replace or increase or decrease the number of drive axles of a certain type, and use multiple drive axles with different performances, different tonnages and different uses. This will greatly facilitate the work of supplier development, product procurement, production organization management and after-sales service.
"The second is to keep pace with the times in terms of specialization and lightweighting." According to Cheng Jinjin, Hanma Axle provides specific products for each market segment according to the conditions of use of vehicles. Lightweight single-stage deceleration bridges adopt more new materials, optimize structural design, and form high-strength steel pipe expansion process. The yield strength is high, the weight is light, the transmission chain is short, the transmission efficiency is high, the components are highly integrated, the wearing parts are less, the reliability is high, the weight is light, and the different products are 50-200KG lighter than the market competing products, and the advantages are obvious.
"Third is high mechanical efficiency. Hanma axle speed range is wide, with Hanma engine, Hanma gearbox, fuel saving effect is more significant. For example, floating, flush welding, unequal thickness brake shoes design, can Effectively prevent the brake shoes from being stuck, improve the safety and environmental protection life by 30% and realize quick replacement of the brake lining. Maintenance-free design of the tie rod ball head, maintenance-free hub unit, no need to fill oil, grease, and reduce maintenance cost in the whole life cycle Improve vehicle attendance, thereby reducing customer operating costs, and the oil-lubricated hub assembly can be directly interchanged with grease-lubricated wheels; maintenance costs are significant."

According to Cheng Jinjin, the fourth aspect is that the Hanma axle is very load-bearing. The front axle is forged and formed by the die forging process, and the strength is high; the cast steel axle shell, the reinforced bearing, the brake, the steel hoop brake drum, the large modulus and other high reduction gears are designed, the load is greatly improved, and the strength is increased by 15%. The maximum output torque is 10% higher than that of the same class drive axle in the market, which is suitable for large tonnage heavy-duty engineering vehicles in various complicated working conditions.
“In the end, the Hanma axle market is very responsive. We responded to customers and responded quickly. By continuously improving product quality and price ratio, competitiveness, and differentiation advantages, we can provide customers with better products than competing products. And service." Cheng Jinjin said.
The reporter learned that because of the rainy day, Hualing Xingma has its own core power chain of the national six Han horses, including Hanma Power's 8 liter, 9 liter, 10 liter, 11 liter, 12 liter and 13 liter tractors and dump trucks. Mixer products, horsepower segment and product specifications are complete, more competitive. The listing of these six new products in these countries will bring new market opportunities to Hualing Xingma.
