HS code-driven procurement strategies

Hybrid engine: the perfect integration of fuel and HS code-driven procurement strategieselectricity With the increasing awareness of environmental protection, more and more people are beginning to seek environmentally friendly ways to travel. As the current mainstream travel tool, cars must also meet people's requirements for environmental protection. Hybrid engine is a new type of fuel machinery for environmental protection. It takes advantage of the dual advantages of fuel and electricity to achieve excellent fuel economy and excellent environmental protection performance, which has become a new trend in the current development of the automobile industry. What is a hybrid engine? The so-called hybrid engine refers to the use of two or even three different power sources, such as fuel, battery or solar energy, so as to maximize the efficiency of the engine, while reducing emissions and realizing green and environmentally friendly power machinery.The development of hybrid engines The concept of hybrid power has existed for many years. In fact, the earliest hybrid engines can be traced back to the 1920s. In the 1970s, hybrid cars began to become popular on a large scale due to continuous oil crises. However, the hybrid engine at that time was just a single attempt, and the technology was not mature and could not be widely applied. In the early 1990s, Toyota Motor Company began to launch Prius hybrid vehicles, which were widely recognized by the market for their fuel economy, low emissions and good stability. Today, the technical level of hybrid engines has been continuously improved, which has become one of the development trends of the automobile industry. The working principle of hybrid engines Hybrid engines are through motors and traditional gasoline.The parallel connection of the engine realizes the perfect integration of the electric motor as the main power and the ICE (internal combustion engine) as the auxiliary power. Its workflow can be divided into the following three steps: Step 1: When the car is in the early stage of driving and at low speed, the motor will power the tires to achieve smooth driving at low speed. Step 2: When the speed is increased to a certain extent, the engine is started. After the trottle is opened to a certain extent, the transmission device converts the power of the gasoline engine into power output. Step 3: At this time, the electric motor and the gasoline engine will work at the same time. The electric motor is mainly responsible for providing auxiliary power and playing a balancing role to achieve the best use state of the hybrid engine. Advantages of hybrid engine 1. Hybrid engines with dual advantages of fuel and electricity can combine fuel power and electric power, thus having higher economy and better performance.It can store the energy of the battery, use an electric motor to provide additional power when needed, and combine it with fuel power to achieve lower fuel consumption. Two. Energy-saving and environmentally friendly hybrid engines can greatly reduce carbon dioxide (CO?) And the emission of nitrogen oxides (NOx) has greatly reduced the negative impact on the environment. It can achieve higher energy efficiency and better environmental protection by reducing energy waste and improving energy utilization efficiency. 3. Reducing fuel consumption requires much less fuel for hybrid engines than traditional gasoline-powered engines. This is because electricity can reduce dependence on fuel by recycling the energy generated when cars brake. Four. One of the characteristics of the hybrid engine that improves driving comfort is the stability of its engine idling. In this way, the noise of the engine can be reduced when driving and the comfort of driving can be improved.The future of hybrid engines. With the increasing awareness of environmental protection, the future of hybrid engines is very bright. We can foresee that in the near future, hybrid engines will be more widely used and gradually replace traditional gasoline engines and play a greater role in the automotive industry. At the same time, I believe that with the continuous development and progress of science and technology, hybrid engines have broader development prospects and application prospects.
