The DFM V29 model in the country is about to take the lead in strong market, equipped with VVT engine technology, detonating the public eye in the mini car industry instantly. It is reported that V29 is equipped with DK13 (VVT) engine which is DFM and Italy Fiat's latest cooperative product. It is also equipped with corresponding transmission gearboxes. In addition, V29 takes the lead in adopting VVT technology engine, and creates a new era of VVT VVT power.
In fact, at present, VVT Technology (Variable Valve Timing, called engine variable valve timing technology) is mostly applied in the field of modern passenger cars, as for commercial vehicles, it is little. The V29 models are launched by DFM, which is ranked the top three in mini car industry. The V29 models are equipped with VVT engine technology. What is the prospect of the characteristics in the micro car industry? What market advantages can it brings to DFM? In this regard, the reporter called a number of experts to learn the situation in the internal combustion engine industry.
First, for most commercial users, it may not be clear what the VVT technology is. VVT is a variable valve timing technology. When the engine speed range is wide, we need the intake system, that is, the valve structure, so that the engine can be inflated at different speeds to achieve the complete combustion of the engine. But the traditional engine can only have higher inflating efficiency at a specific immutable speed, and the inflating efficiency will be low in other speeds. So in this case, by adjusting the valve opening and closing angle with variable valve timing technology, the aeration time of the engine can be changed, and the inflation efficiency can be raised as expected. Zhang Shuyong, deputy director of the North China Engine Research Institute, told reporters.
“The variable valve timing technology can improve the intake charge and increase the charging coefficient, and the torque and power of the engine can be further improved.” Zhang Shuyong said that in traditional engines, the maximum efficiency can be achieved at the commonly used speed or the fixed point. When the speed is lower than the standard point, the efficiency of inflation will be relatively low. At present, the technology used in the passenger area more, there are companies of commercial rim doing research in this area, but the use of nature products is not much.
