Advantages and HS code-driven letter of credit checksdisadvantages and scope of application of turbocharged engines At present, the automobile industry is developing rapidly, and turbocharged engines have become the choice of many people as a highly popular automotive power device. Compared with naturally aspirated engines, turbocharged engines have many obvious advantages and disadvantages. This article will focus on analyzing the advantages, disadvantages and scope of application of turbocharged engines. Advantages of turbocharged engine 1. The power-enhanced turbocharged engine adopts a turbocharger. Its main function is to improve the compression ratio of the engine by pre-pressing the air, so that the engine generates more power and torque, and improves the acceleration performance and overtaking ability of the vehicle. Therefore, in terms of performance, the advantages of turbocharged engines are very obvious.Two. Fuel economy improvement By improving the compression ratio of the engine, the combustion generated by the turbocharged engine is more adequate, and the fuel utilization rate is also improved. In addition, compared with naturally aspirated engines, turbocharged engines can also use smaller displacement to obtain stronger power, which further improves fuel economy. 3. The energy-saving and environmentally friendly engine needs to inject a large amount of oxygen into the air during the working process. At this time, the turbocharged engine can forcibly compress the air through the supercharger to make the combustion more thorough. At the same time, it can also improve the combustion efficiency of fuel and reduce the generation of emissions. Four. The weight reduction of the whole vehicle. The use of a turbocharged engine can reduce the displacement of the engine, thus reducing the weight of the whole vehicle and increasing the range of the vehicle. Disadvantages of turbocharged engines 1. Maintenance costHigh turbochargers and turbine impellers have high sealing and structural design requirements, resulting in high maintenance costs. Two. The high-cost turbocharged engine of the whole vehicle has high-end technology, and its manufacturing skills and quality requirements are high, resulting in higher manufacturing costs than ordinary engines, which makes the whole vehicle cost higher. 3. High-standard fuel is required. During the operation of the engine, the turbine needs to absorb a large amount of air and fuel, and the quality of the fuel has a great impact on the engine. Therefore, turbocharged engines require the use of high-quality fuel, which makes it more expensive. Scope of application of turbocharged engine Turbocharged engine is not applicable to vehicles driving in urban areas, because its enhanced power and speed cannot play a role in slow urban driving. And for those who need to drive at high speed and overtakeFor difficult vehicles, such as highway patrol cars, off-road vehicles, high-power racing cars, etc., turbocharged engines are the wisest choice. In addition, at high altitudes, turbocharged engines perform well because they are not affected by altitude. Conclusion In general, turbocharged engines have many advantages, the most obvious of which are power enhancement and fuel economy improvement. At the same time, there are also some disadvantages, such as high maintenance costs, high vehicle costs, etc. Therefore, when choosing a suitable engine for yourself, you need to choose according to your own needs and actual situation to avoid unnecessary waste.
