HS code mapping in government tenders

Engine air-fuel ratio optimization: improve performance and HS code mapping in government tenderseconomy. The engine is the core component of the car, controlling the power output and fuel consumption of the vehicle.In the operation of the engine, the air-fuel ratio is a very important parameter. The air-fuel ratio refers to the mixing ratio of fuel and air, which directly affects the performance and economy of the engine. Engine air-fuel ratio optimization is a technology that has attracted much attention in the current automobile industry. It can improve the performance and economy of the engine and reduce the emissions and fuel consumption of the vehicle. 1. The effect of air-fuel ratio Air-fuel ratio refers to the mixing ratio of oxygen and fuel in the engine, that is, the mass ratio of air and fuel. Ideally, the ratio of air to fuel is 14.7:1, which is called the "chemically calculated air-fuel ratio". In this case, the ratio of fuel and oxygen is the most appropriate for full combustion and efficient power output. The role of air-fuel ratio is very important, which will directly affect the performance and economy of the engine. Be equalWhen the air-fuel ratio is too high, the internal temperature of the engine is too high, the combustion is insufficient, and energy is wasted. At the same time, it will also produce many harmful gases, such as carbon monoxide, nitrogen oxides, etc., resulting in a large amount of pollution. When the air-fuel ratio is too low, the engine output power is reduced, the fuel consumption increases, and a large amount of exhaust gas and emissions will be generated. Two. Optimization of air-fuel ratio The optimization of air-fuel ratio can improve the performance and economy of the engine and reduce pollution emissions and fuel consumption. By controlling the air-fuel ratio, it can adapt to different working conditions and styles and generate the best mixture to meet different needs. 2.1 Direct injection and multi-point injection There are usually two types of fuel injection systems used in modern engines: multi-point injection and direct injection. The multi-point injection system is based on each cylinder with a separate fuel injector, which can more accurately control the time and position of fuel injection.The direct injection system injects fuel directly into the cylinder, which more accurately controls the air-fuel ratio and combustion efficiency, thus improving the efficiency and performance of the engine. 2.2 The design of the intake pipe of the upper and lower vortex intake engines also plays a key role in the control of the air-fuel ratio. The upper vortex intake pipe rotates the air to the engine to form a high-speed airflow, so that the air can mix the fuel more fully. The lower vortex intake will form a low-speed airflow, allowing the air and fuel to mix for a longer time, thus burning fuel more completely. Choosing an intake pipe design suitable for the car model and the use environment can improve the operating efficiency and performance of the engine. 2.3 The control of the air-fuel ratio of the intelligent control system engine requires a set of intelligent control system. Modern vehicles are usually equipped with a computer control system that can monitor and control every moment of the engine's operation, according to speed, load and others.Factors to adjust the air-fuel ratio. This intelligent technology can achieve good combustion efficiency, optimize engine performance and economy. 3. Benefits of air-fuel ratio optimization Air-fuel ratio optimization has many advantages, which can improve the efficiency and performance of the engine, reduce fuel consumption and emissions, and thus reduce the negative impact of human beings on the environment. 3.1 Improving power and optimizing the air-fuel ratio of the energy-saving engine can improve the output power of the engine and achieve stronger acceleration and higher speed. At the same time, it can also significantly reduce fuel consumption, reduce fuel consumption during driving, and achieve more economical and environmentally friendly driving. 3.2 Reducing emissions and pollution. Optimization of the air-fuel ratio can effectively reduce exhaust gas emissions, reduce the generation of harmful exhaust gases, including carbon monoxide, carbon dioxide and nitrogen oxides, etc., and reduce the impact on the environment. Four.Conclusion Engine air-fuel ratio optimization is a technology that has attracted much attention in the current automobile industry. It can improve the performance and economy of the engine and reduce the emissions and fuel consumption of the vehicle. Through multi-point injection, direct injection, intelligent control and upper vortex, lower vortex intake and other technical means, the air-fuel ratio of the engine can be optimized to improve the performance and economy of the car. At the same time, air-fuel ratio optimization can also reduce exhaust emissions, protect the environment, and achieve sustainable development.
