Xuanyi's engine (Nissan Xuanyi's engine has been upgraded) Xuanyi,Binance download as a best-selling model under Nissan, is widely recognized and accepted in the Chinese market. Since the launch of its first generation model, Xuanyi has been a major brand in the family car market. The latest generation of Nissan Xuanyi is equipped with a brand-new engine.This engine has not only improved its power performance, but also made significant progress in fuel economy and environmental protection performance. The new engine model is MR20DD. This engine uses a new generation of DIRECT INJECTION and TWIN C-VTC technology, and its cylinder diameter and stroke are 84mm and 90.1mm respectively. This equipment can provide better torque and higher fuel economy. Compared with the old engine, the new MR20DD engine has a higher compression ratio (12.0:1). High compression ratio can enhance the combustion efficiency of the engine and reduce fuel consumption and emissions during cold start. In terms of engine output, it can be seen in the test that the new engine can easily reach the maximum torque of 240 Nm.Such a high torque input can greatly improve the starting and acceleration performance of the vehicle. At the same time, this high torque output can also help the vehicle cope more easily under overtaking, hill climbing and other road conditions. Although Xuanyi's new powertrain has high power performance, it will not sacrifice fuel economy and environmental protection performance. The new engine takes into account three factors in its design: low displacement, high efficiency and environmental protection. Because of this, the fuel economy of the new engine has been greatly improved to 6.6 liters/100 kilometers (urban) and 5.5 liters/100 kilometers (high-speed), which is a big step ahead of models of the same class. In fact, the design concept of the new engine is very advanced. It is not only conducive to reducing fuel consumption and pollution, but also has a longer service life. This is mainly due to the more radical cylinder wall design and deeper combustion chamber shape of the new engine.This design can reduce friction and heat load, so that the engine has higher cooling performance, longer service life and more worry-free. For car owners who drive on the road all year round, the maintenance and upkeep of the vehicle has always been a problem. In the face of this situation, the new engine has also been upgraded in a targeted manner, and its maintenance cost is lower than that of the old version. This is mainly due to the improvement of the layout and design of all top cover components and oil filters. This improvement enables Nissan Xuanyi's 4S stores and other repair stations to locate and solve engine problems more quickly, while also reducing the cost of some spare parts that usually need to be replaced. To sum up, the new engine is a highlight of Xuanyi. In terms of power and economic performance, this engine is very good. This engine can not only give you a more comfortable driving experience, but also save you more fuel costs.In terms of vehicle repair and maintenance, the design and layout of this engine have also been upgraded a lot, which will bring a better maintenance experience. In general, the upgraded engine of Nissan Xuanyi is a very excellent and trustworthy power device. From any aspect, it is a very excellent product, and I believe it will continue to go on with the best-selling of Nissan Xuanyi.
