Engine air intake mode: diversified developmentAs the core component of modern automobiles,Global trade intelligence newsletter the performance and stability of the engine are directly related to the quality and safety of the car. Of course, as a key component of the engine, the air intake system is also very important, which is not only related to the efficiency of the engine, but also directly affects the power output and fuel economy of the whole vehicle. This article will briefly describe the air intake mode of the engine and its diversified development trend. I. In the current market, the air intake method of the engine is mainly divided into two types according to the valve configuration, the number of cylinders, the working principle and other factors of the engine: 1. Naturally aspirated air intake system. Natural aspiration refers to the engine using the downward pressure of the piston and partial negative pressure of the combustion chamber to directly suck air into the cylinder through the valve. The most common application of this air intake method is in ordinary passenger models.Due to its simple structure, reliable operation, small oil storage and good economy, this type of engine is widely used in the market. The power generated by the naturally aspirated engine in the drive is relatively stable, and the output horsepower is relatively small, so it is suitable for general vehicles. Two. Turbocharging means that the engine is equipped with a supercharger in the intake duct, which compresses the atmospheric pressure through the supercharger and then transports it to the spiral intake chamber, so as to obtain higher intake pressure and improve the output power and torque of the engine. Turbocharged air intake systems are usually used in performance models, racing cars and other high-performance models. Because it can adjust the air pressure to the most suitable pressure for engine operation, it can improve the output power of the engine without increasing the volume ratio of the engine, thus achieving higher performance.II. Diversified development trend The development of the air intake system has a very important impact on the performance and fuel economy of the whole vehicle. With the continuous improvement of energy and environmental protection requirements and the development of technology, the continuous diversification and development of air intake systems has become an inevitable trend. 1. Hybrid vehicles usually combine engines and electric motors, which is more efficient in energy utilization than simply increasing the output energy of the engine. In the development of the air intake system, in addition to turbocharging and natural aspiration, some hybrid models also adopt "inspiration supercharging" technology, that is, using motor-driven turbochargers to provide pressure to the engine, which can greatly improve its fuel economy performance while enhancing engine power transmission. In the future, with the continuous upgrading of motors and batteries, the hybrid air intake system will become more and more diversified and intelligent.Two. Intelligent air intake system Intelligent air intake system refers to a system that can intelligently adjust the air intake mode according to the current gas quality, oxygen content, temperature and other conditions. This technology has now begun to be applied to the field of high-end cars. The emergence of intelligent air intake system will further improve the power, economy and reliability of the engine. 3. Fuel injection technology Fuel injection technology refers to the injection of fuel to the spark plug by sending compressed air, which can achieve a more rational and efficient combustion reaction. This technology has been widely used in diesel engines, which can greatly improve fuel efficiency, and is expected to further derive various innovative technological applications in the future. In a word, the diversified air intake system application breaks the limitations of traditional engines, can give full play to the performance potential of the engine, and also meets the requirements of energy saving and environmental protection. Future, intelligenceThe high-efficiency and energy-saving air intake system will be the inevitable trend of the engine, which will certainly further promote the development of the entire automobile industry.
