The year 2018 was a crucial year for the FAW Liberation Engine Division to implement the 13th Five-Year Development Plan. It was also a year of positive development and concentrated outbreak. Recently, the reporter learned from the Engine Division that the 6DM3, 6DL3 launched by the Engine Division this year. , 4DB1's three 'new stars', will be used as a 'national brand, high-end power' new business card, set off a 'C-bit' battle on multiple power platforms.
So, what kind of energy does the three new stars have in the end?
Aowei 13L engine
It is understood that 13 liters is known as the 'gold displacement' of heavy-duty truck engines. As a new member of the M series, the Aowei 6DM3 engine inherits the 6DM2 engine's high power, long oil change, long three packs, low fuel consumption, and safe enough piloting characteristics. , Efficient combustion control technology, 1.5 million kilometers long life technology, 100,000 kilometers long oil change technology, 2000bar electronically controlled high pressure common rail technology, low friction technology, high power engine braking technology, low NVH technology and lightweight eight core technologies , combed the industry's new standards. At the same time, 6DM3 diesel engine external characteristics of the minimum oil consumption of 185g/kWh, the total weight loss of more than 70 kilograms, the maximum torque of 2300N · m, the use of domestic first independent rocker brake technology, braking The efficiency is further increased by 30% on the basis of the original solid-chain brake. The downhill brake is more effective and the deceleration brake is more powerful. On April 18 of this year, with the emancipation of the seventh-generation heavy truck officially on the historical stage, Aowei 6DM3 will Continue to lead the development of heavy-duty diesel engine market, becoming the absolute weapon for the liberation of J7 to compete in the high-end logistics market.
The Aowei 6DL3 engine is based on Aowei's 6DL2 series engine, which is optimized by strengthening the structure. The fuel part adopts an electronically-controlled high pressure common rail system. The post-treatment mode is the EGR+DPF+SCR technology route. The maximum power is 350 hp. The peak torque of 1500 Nm is achieved between 1300-1600 rpm. At the same time, it has excellent fuel economy. It is reported that except for the cylinder structure and the 6DL2, the four-valve cylinder is newly designed for this 9-liter machine. The lid, body, crankshaft, connecting rod, piston, bearing bush and other parts are all in accordance with the Euro VI requirements, to strengthen the upgrade. According to reports, 6DL3 is currently the most mature country VI products.
Jinwei 4DB1 light diesel engine shows the characteristics of 'small hull and large power'. Lightweight is one of the most important features of the aircraft. The weight of the whole machine is only 250 kilograms. The displacement of 2.2 liters can produce a maximum torque of 330 Nm. , Greatly ahead of similar products. As the power output of the Liberation J6F, the engine engine adopts the technical route of EGR+DOC+DPF, meets the national five standard, and has more potential in Europe. In the future, the Jinwei CA4DB series diesel engine will be gradually consolidated. Wei series of related products, into better technology, and as a whole new generation of light high-end engine products to market.
FAW Liberation Engine Division
The injection of fresh blood is a magic weapon for this 75-year-old state-owned enterprise to maintain its youth. For many years, the engine business unit has insisted on high R&D investment, the engine design concept is at the advanced level in the world, the product quality industry is leading, and the product failure rate continues to decrease. To ensure the continuous upgrading of the product.
According to Huang Chenghai, deputy general manager of engine business division, annual investment in R&D expenditures of the Engine Division accounts for more than 5% of total sales. Currently, there are 96 R&D equipments in total. There are 20 sets of six development platforms in China, with 10 performance and reliability. The full-flow certification laboratory has an international leading spray-burning optical constant volume bomb and single-cylinder machine. It is the long-term investment in product research and development and technological innovation, which has laid the engine industry's leading position in the engine division and further consolidated the engine business unit. The foundation of technological innovation.
