DVVT intake and exhaust continuously variable timing system, using double intake and exhaust VVT technology, so as to obtain the rotational speed that more closely matches the valve angle superimposition , intake timing phase provides maximum 70deg; variable angle of crankshaft rotation, the phase of the exhaust valve timing to provide maximum 60deg; variable angle of crankshaft rotation, the intake and exhaust are as fully as possible, has a higher valve efficiency, greater power to obtain the torque and the emission performance.
Twin Scroll double channel turbine technology effectively improve the efficiency of the turbine, the exhaust phase interfere with each other 1,4 2,3 cylinder and the exhaust cylinder are led to the turbine, to avoid exhaust interference, reducing the exhaust gas energy loss, improve charging efficiency, the double vortex channel design to enhance the percentage of 7 percent -8 turbine efficiency, and can provide fuel efficiency percentage 5; significantly reduce turbo lag phenomenon turbo lag reduce 1.5s; two channels to scroll jointly promote the rotation of the turbine, improve low-speed torque, low speed turbine intervention allows drivers to clearly feel the power AX7 paragraph 2020 come faster.
tooth skipping prevention timing protection system designed to prevent tooth skipping phenomenon occurs, reducing the chance of failure. Generation crankcase ventilation system, in a conventionalDouble outer leg crankcase ventilation system for a supercharged engine, increasing the gas pipe is diluted, reducing the proportion of the crankcase ventilation exhaust, improving the oil separation effect and reduce carbon deposition. Further, the engine which also uses a lightweight engine design, high strength, low friction and a hollow piston assembly Waxed sodium valve applications, improving reliability. Different from many manufacturers over the pursuit of high power and performance, resulting in reduced lifetime limit press the engine, resulting in engine failure rate is high fat, Dongfeng Fengshen balanced powertrain low fuel consumption, high performance, lightweight, stability, and to provide consumers with the most power gifted program.
developers own experiences, the quality of confidence from ingenuity demanding
the ultimate achievement of a technical the birth of high-performance engines, the quality of the demanding market achieved a hard-core products. Deputy Minister of Power Development Department Technology Center of Dongfeng Automobile Company Li Canfeng years fighting in the first line of quality control, section 2020 witnessed the whole process from development to AX7 off the assembly line, as the Dongfeng Fengshen transition break, shifting the growth rate of the main models, positioning “ecological wisdom SUV” section of the 2020 Dongfeng Fengshen AX7 inherited the genes of high-quality, face the urban users look to leapfrog SUV models, using the core contains TVDI BMW’s second-generation core technology EP6 1.6THP engine with stable performance known gold powertrain Aisin three generations 6AT transmission, through 15,000 hours test bed test, 500 special evaluation of Quality Supervision, final calibration data not only to achieve the perfect balance of high performance and low fuel consumption, but also to the low failure rate, smooth high reliability reached a good commitment to consumers. There is also a group of dedicated quality “goalkeeper”, Dongfeng Fengshen only “limited kilometers years warranty” confident of quality.
the strength of the testimony of senior owners, stable performance achievements worry vehicles
